A reminder to watch live video: Bears still active
at Alaska’s Brooks Falls

Brown bears are still actively fishing at Brooks Falls in Alaska’s Katmai National Park and Preserve. I wish I had more time to sit and watch them, as there is almost always something going on at this time of year — although the salmon run is expected to decline soon. See live video from three cameras on Explore.com.

The looping video on this page was captured from one of the live cameras by national park staff, who posted the action with this note: “Wow, fishing gets intense! Bear brawl!”

For this and other live wildlife cams from across the country, check out my “Amusing Monday” blog post in Water Ways from June 29.

Amusing Monday: Bears, birds and more can be viewed live online

The beautiful and powerful brown bears have arrived at Brooks Falls in Katmai National Park and Preserve in Alaska, and everyone in the world can enjoy the convenience of watching these giant bears and other amazing wildlife live from the comfort and safety of their home.

Lots of people have been going out to falls this year to watch the bears from nearby viewing platforms, but I get the feeling that far more people have been watching them from home via the live webcams. I say that because of the number of comments generated on the website. More than a few commenters seem to know the area well and even call the bears by their nicknames. (Park biologists use a numbering system, identifying each bear by coat and claw colors, scars, body size and shape, ear size and shape, sex, facial features and disposition.)

Brooks Falls is one of the first streams in the region where the bears have easy access to bright salmon soon after they leave the saltwater and before spawning. The falls provide a partial barrier to their travels, making fishing easier for the bears. By sometime in August, the fish runs will dwindle and the bears will be gone.

Operators of the multiple live webcams do a good job of zooming in when something interesting happens. Occasionally, so much is going on that they don’t know what to show. Other times, we wait and watch the beautiful scenery, which is especially dramatic at sunrise and sunset.

When the bears are actively fishing for salmon, I find it hard to break away and get back to daily life. One video trick I’ve learned: If you don’t see anything interesting in the live view, you can use your cursor to scan across the timeline to see what has happened for the past few hours and watch that instead.

Park officials have identified the various fishing methods used by the bears in an interesting Q&A section on the national park’s website.

Birds and marine mammal cams

Besides watching bears, it’s a good time of year to watch other wildlife as well via live webcam. Birds are typically active on their nests, raising their young.

Chesapeake Conservancy is featuring the osprey couple, Tom and Audrey, who perennially nest on Kent Island in Maryland. Audrey has taken up with a new “Tom” this year and produced three babies. They also received two foster chicks from nearby Poplar Island, according to information on the website.

Another good osprey cam was installed this year in Belwood Lake Conservation Area near the Great Lakes in Ontario, Canada. Three eggs reportedly hatched, but I see only two chicks in the nest.

Washington Department of Fish and Wildlife also has an osprey cam that updates still photos every 12 seconds.

A puffin cam at Seal Island National Wildlife Refuge in Maine shows a fuzzy chick tucked into a burrow where its mother comes and goes to feed her baby. Other views shows puffins on a ledge where they often hang out. Wildlife biologists are trying to establish a new colony at this location after hunters wiped out the puffins in the 1800s.

Another live camera on Seal Island shows a guillemot in a burrow.

If you would like to see a colony of walruses, (also in video player below) check out the live camera installed on Round Island, Alaska. Sometimes only a few of the large mammals can be seen. Other times, like this morning, large numbers were pushing and shoving each other for space. The comments are often entertaining.

Meanwhile, the Seattle Aquarium is featuring live cams from its displays of harbor seals and sea lions.

New website reveals strategies for improving Hood Canal ecosystem

If you want to know how the Hood Canal Coordinating Council is working to protect and restore Hood Canal, take a look at a new website created by the council. It is called OurHoodCanal.org.


The website is an attractive and functional companion to the “Hood Canal Integrated Watershed Plan” (PDF 325 kb), a five-year strategic plan focused on programs that can be accomplished by the coordinating council and its members.

Hood Canal Coordinating Council is made up of county commissioners from Kitsap, Mason and Jefferson counties, along with leaders from the Skokomish and Port Gamble S’Klallam tribes.

When planning efforts began five years ago, the idea was to create an “integrated” plan that would recognize all the ecological functions taking place in the Hood Canal watershed and create a set of strategies for addressing all the various problems.

The effort got off to a good start by identifying many of the problems, ranging from declining fish populations to fragmented upland habitats. But the complexity of those problems, the variability of conditions and the numerous agencies responsible for data and decisions eventually overwhelmed the planners. It was as if they were trying to complete a jigsaw puzzle containing a million pieces.

The coordinating council decided to refocus the effort on issues that are under its purview while maintaining the long-term vision of a sustainable Hood Canal ecosystem that benefits humans in a variety of ways.

“Ideally, we will eventually get to all the issues,” said Scott Brewer, the council’s executive director. “The board decided it wanted to focus on something that would be the first strategic priorities and then pick up the other things over time.”

In this context, the plan identifies five focal components:

  • Shellfish,
  • Commercial shellfish harvesting,
  • Forests,
  • Forestry, and
  • Salmon.

Also, four major “pressures” are called out for special attention:

  • Commercial and residential development,
  • Transportation and service corridors,
  • Climate change and ocean acidification, and
  • Wastewater discharges and stormwater runoff.

These are issues that the county and tribal leaders were already addressing in one way or another, either through local actions or through the Hood Canal Coordinating Council, which is recognized under state law.

The new website OurHoodCanal.org highlights the connections between human well-being and natural resources. The first findings focus on three natural resource indicators — one each for shellfish, forests and salmon — plus five indicators for human well being — positive emotions, communication, traditional resource practices, communities, natural resource industries and access to local food.

A survey last year, for example, showed that Hood Canal generates positive emotions (at least most of the time) for the vast majority of respondents, yet most Hood Canal residents say they don’t often work together to manage resources, prepare cultural events or solve community challenges.

The website also includes a section about what people can do to help Hood Canal.

“This is a work in progress,” Scott said about the planning effort and related website. “We can start by telling a really good story about what is happening in Hood Canal, then going on to make connections and asking whether we are doing the right things.”

The first strategies identified in the plan involve:

  • Working together on local land-use planning,
  • Identifying failing septic systems and other sources of bacterial pollution,
  • Continuing projects to restore healthy runs of salmon,
  • Furthering a mitigation program to fully compensate for the effects of development,
  • Finding ways to adapt to climate change, and
  • Developing a regional plan to reduce stormwater problems.

Meanwhile, the coordinating council has developed a new ranking system for setting priorities for salmon restoration. Refinements will come later, Scott said, but the system is currently being used to identify restoration projects to be proposed for funding later this year.

Under the Salmon Recovery Prioritization (see “guidance” document) projects will be given more consideration if they help highly rated salmon stocks, such as fall chinook in the Skokomish River, summer chum in the Big Quilcene and so on. Projects are given points for addressing specific habitat types and restoration actions deemed to be the most important.

If successful, this approach will result in funding the most important restoration projects, as determined through a more precise ranking process than ever used before, although it does leave room for judgment calls.

While the Hood Canal Coordinating Council works on projects in Hood Canal, other groups continue with similar efforts in other watersheds.

“Everyone is prioritizing one way or another,” Scott told me, “but they haven’t looked at it like we have.”

Scott said agencies and organizations that grant money for salmon recovery or ecosystem restoration could call for an improved ranking process throughout Puget Sound.

“A lot of money gets spread everywhere,” he noted, “but there are some key spots throughout Puget Sound that need it more than others.”

Amusing Monday: Wolves found to catch and eat wild salmon

I’m amused by this looping video, which shows a bear waiting for a fish to appear. In the background, a wolf reaches down nonchalantly, bites into a large salmon and carries it away.

Not long ago, it was widely believed that bears love salmon but that wolves prefer deer, elk, moose and related animals whenever they can find them. Now we know, from careful observations in Alaska, that wolves will go after salmon when they get the opportunity.

Researcher Dave Person of the Alaska Department of Fish and Game says wolves will seek out tidally affected streams where they can find salmon passing through shallow water and trapped in pools.

“They’re not as skillful as bears at fishing,” Person told Riley Woodford, reporting for Alaska Fish and Wildlife News. “Each year, they spend over a month in estuary areas, with the pups. It’s right in middle of pink and chum runs, and we watch them eat salmon all the time. There are lots of places they could go; I think they go there for the fish.”

Based on the video, I would have to say that wolves are pretty good at catching fish upstream as well.

Salmon may have gone unnoticed as a staple in the wolves’ diet, because the entire salmon, bones and all, are digested by wolves, leaving no signs of fish in their scat — unlike the bones and fur discovered after they eat a deer or other mammal.

Another Alaskan biologist, Shelly Szepanski, has been studying the stable isotopes of carbon and nitrogen in wolf bones to see whether the bones are made of elements that come from the land or the sea. She found that salmon appeared to make up as much as 20 percent of the diet of wolves living in coastal areas of Southeast Alaska, compared to 10 percent of those living farther inland.

As I continued to look at the video of the bear and wolf fishing for salmon, I wondered if they ever interacted and how things might turn out in a head-to-head fight. I was able to find a video that demonstrates that a bear might get the best of a wolf in a one-on-one battle, but we can never forget that wolves often travel in packs. If you watch to the end, you will see who takes charge of the meal in question.

For another video showing wolves eating salmon, in which a bear plays a minor role, check out this video posted by Tinekemike.

Speaking of fights, I am still amazed at the video below, which shows a leopard swimming across a stretch of water, grabbing onto a crocodile and dragging it back into the water. I never would have guessed that a croc could be defeated in or around water like that — but it looks like he never saw the cat coming until it was too late.

Climate change disrupts steady streamflows, adds problems for chinook

Climate change appears to be altering the flow characteristics of Puget Sound salmon streams, and the outcome could be an increased risk of extinction for chinook salmon, according to a new study.

I’ve long been interested in how new housing and commercial development brings more impervious surfaces, such as roads, driveways and roofs. The effect is to decrease the amount of water that infiltrates into the ground and to increase surface flows into streams.

Stormwater experts talk about how streams become “flashy,” as flows rise quickly when it rains then drop back to low levels, because less groundwater is available to filter into the streams.

The new study, reported in the journal “Global Change Biology,” suggests that something similar may be happening with climate change but for somewhat different reasons.

Climate models predict that rains in the Puget Sound region will become more intense, thus causing streams to rise rapidly even in areas where stormwater is not an issue. That seems to be among the recent findings by researchers with NOAA’s Northwest Fisheries Science Center and Washington Department of Fish and Wildlife:

“Over the last half century, river flows included in our analysis have become more variable — particularly in winter — and these changes are a stronger predictor of chinook population growth than changes in average winter flows or climate signals in the marine environment.

“While other impacts to this ecosystem, such as habitat degradation, may be hypothesized as responsible for these trends in flow variation, we found support for increasing flow variation in high-altitude rivers with relatively low human impacts.”

Joseph Anderson of WDFW, an author of the report, told me that chinook salmon, listed as threatened under the Endangered Species Act, may be particularly vulnerable to dramatic changes in streamflows. That’s because spawning chinook tend to show up before winter storms arrive — when the rivers at their lowest levels. The fish are forced to lay their eggs in a portion of the river that will undergo the most forceful flows once the rains begin to fall.

High flows can scour eggs out of the gravel and create serious problems for emerging fry, Joe said. Other factors may come into play, but the researchers found a strong correlation between the sudden variation in streamflows and salmon survival.

In the lower elevations, where development is focused, flow variability could result from both impervious surfaces on the land and more intense rainstorms. Efforts to infiltrate stormwater into the ground will become even more important as changes in climate bring more intense storms.

Stormwater management is an issue I’ve written about for years, including parts of last year’s series called “Taking the Pulse of Puget Sound.” See Kitsap Sun, July 16, 2014. Rain gardens, pervious pavement and infiltration ponds are all part of a growing strategy to increase groundwater while reducing the “flashiness” of streams.

Other strategies involve restoring rivers to a more natural condition by rebuilding side channels and flood plains to divert excess water when streams are running high.

According to the report’s findings, the variability of winter flows has increased for 16 of the 20 rivers studied, using data from the U.S. Geological Survey. The only rivers showing less variability were the Cedar, Duwamish, Upper Skagit and Nisqually.

The effect of this streamflow variability was shown to be a more critical factor for chinook survival and growth than peak, total or average streamflow. Also less of a factor were ocean conditions, such as the Pacific Decadal Oscillation and related ocean temperature.

Eric Ward, of Northwest Fisheries Science Center and lead author on the study, said many researchers have focused attention on how higher water temperatures will affect salmon as climate change progresses. High-temperature and drought conditions in California, for example, could damage the organs of salmon, such as their hearts.

Salmon swimming up the Columbia River and its tributaries could encounter dangerously warm waters as they move east into areas growing more arid. Some salmon species are more vulnerable to temperature, while streamflow may be more important for others. Coho salmon, for example, spend their first summer in freshwater, which makes extreme low levels a critical factor.

Eric told me that further studies are looking into how various conditions can affect each stage of a salmon’s life, conditions that vary by species. One goal is to build complex life-cycle models for threatened species, such as chinook and steelhead, to determine their needs under the more extreme conditions we can expect in the future.

Skokomish River gets special attention in salmon funding

Big money is beginning to come together for planning, engineering and design of major restoration projects along the Skokomish River. If approved by Congress, the cost of construction could exceed $40 million — a lot of money to you and me, but maybe not so much for the Army Corps of Engineers.

Last week, the state’s Salmon Recovery Funding Board approved grants for more than 100 projects in 29 counties throughout the state. The total, from state and federal sources, was about $18 million for this round of funding.

Mason County was one of the big winners this time, receiving $1.25 million for seven projects, including a $360,000 contribution to planning and engineering for transformative projects on the Skokomish. The total cost for a “35-percent level of design” is expected to be $2.45 million, mostly from the Corps of Engineers. That level of design is needed to give top officials in the Corps and members of Congress a good idea of cost before they commit to the massive undertaking along the Skok.

I’ll address the specific Skokomish River projects, along with new information from the Corps, in a separate blog post to come. For now, I’d like to describe other projects approved in the latest round of SRF Board funding.

In addition to the design work on the Skokomish, the Mason Conservation District will move ahead with the construction of 21 man-made logjams in the Holman Flats area along the South Fork of the Skokomish. That is an area that was logged and cleared in preparation for a dam that was never built.

Man-made logjams were placed in the Skokomish River in 2010. More will be added thanks to a new salmon-recovery grant. Kitsap Sun photo

The clearing destabilized the river and degraded salmon habitat for more than a mile downstream. The logjams will add structure to the river and create places for fish to hide and rest, ultimately improving the channel itself. The $362,000 from the SRF Board will be supplemented with another $900,000 in grants.

This will be a second phase of a project I wrote about for the Kitsap Sun in 2010, followed by another story in 2011.

Other Mason County projects:

Beards Cove, $297,000: This project, outside of Belfair on Hood Canal, will remove fill, structures and invasive plants and restore the grade to the way it was before development in 1973. The project will restore about a quarter-mile of natural shoreline and seven acres of tidal marsh. Along with a separate seven-acre land-preservation agreement and other efforts, about 1.7 miles of Hood Canal shoreline will be preserved forever. Great Peninsula Conservancy will use a separate $491,000 grant from the state’s Estuary and Salmon Restoration Program.

Allyn Shoreline, $14,000: Mason Conservation District will complete final designs to enhance 480 feet of shoreline along Case Inlet in Allyn, including removal of about 120 feet of bulkhead.

Likes Creek, $85,000: South Puget Sound Salmon Enhancement Group will remove a culvert under the Simpson railroad that blocks salmon migration on Likes Creek, a major tributary of Goldsborough Creek. Another grant will provide $43,000 for the project, and Mason County will assist with removal of another culvert upstream.

Goldsborough Creek, $111,000: Capitol Land Trust will buy 420 acres on the North Fork of Goldsborough Creek near Shelton. The property provides habitat for endangered salmon and steelhead. The land trust will contribute $20,000 in donated land.

Oakland Bay, $24,000: Capitol Land Trust will use the money to remove invasive and dead vegetation and maintain 12 acres of shoreline plantings on Deer, Cranberry and Malaney creeks. About $5,000 in donations will be added.

Three projects were funded in Kitsap County:

Springbrook Creek, $62,000: Bainbridge Island Land Trust will assess the creek’s watershed and design five salmon-habitat projects for one of the island’s most productive streams. The land trust will contribute $11,000 in donations of labor.

Curley Creek, $33,000: Great Peninsula Conservancy will assess how to protect salmon habitat in Curley Creek in South Kitsap, one of the largest salmon and steelhead streams in the area. The conservancy will contribute $6,000 in donations of labor.

Steelhead assessment, $50,000: Kitsap County will analyze existing information on steelhead habitat in the East Kitsap region, south to the Tacoma Narrows Bridge, to help with a recovery plan for the threatened fish. The county will contribute $9,000.

Other notable projects include the following in King, Snohomish, Thurston and Whatcom counties:

Mill Creek, $327,000: The city of Kent will built a floodplain wetland off Mill Creek near the confluence with the Green River, an important stream for chinook salmon and steelhead as well as coho, chum and pink salmon and cutthroat trout. The project includes the construction of 1,000 feet of new off-channel habitat, where salmon can find refuge and food during floods, and 43 log structures. Work also will restore seven acres of native vegetation. A local grant will provide $1.4 million.

Stillaguamish River floodplain, $402,000: The Stillaguamish Tribe will purchase 200 acres on the North Fork and main stem of the river, remove invasive plants and restore about 25 acres of riverbank with native vegetation.

Black River wetland, $90,000: Capitol Land Trust Grant will buy 54 acres to conserve a rare wetland unique to the Black River and protect 1.3 miles of side channel. The property is adjacent to 75 acres already protected by the land trust in the Black River Sub-basin, one of the largest remaining wetland systems in Western Washington.

Nooksack River logjams: The Nooksack Tribe will receive $320,000 for logjams in the South Fork Nooksack and $283,000 for the North Fork Nooksack. Eight logjams in each stream will slow the river and provide resting pools for salmon. Federal grants will add $56,000 in the South Fork and $60,000 in the North Fork.

In announcing the $18 million in salmon-restoration grants statewide, Gov. Jay Inslee commented:

“Salmon are important to Washington because they support thousands of jobs in Washington — fishing, seafood-processing, boat sales and repair, tourism, and more. When we restore land and water for salmon, we also are helping our communities. We get less flooding, cleaner water and better beaches. We also make sure that our grandchildren will be able to catch a fish or enjoy watching the return of wild salmon.”

Funding for the grants comes from the sale of state bonds approved by the Legislature along with the Pacific Coastal Salmon Recovery Fund, approved by Congress and administered by the National Marine Fisheries Service.

David Trout, who chairs the SRF Board, said the restoration projects are a lifeline for salmon:

“Without these grants that fund incredible projects, we wouldn’t have any salmon. That’s unacceptable. We’ve seen these grants make a difference. They create jobs, support local communities and their involvement in salmon recovery, and most importantly the projects are helping bring back the fish.

“After more than a decade of work, we’ve seen that in many areas of the state, salmon populations are increasing or staying the same. At the same time, we still have some important areas where fish populations are continuing to decline. We can’t get discouraged and must continue working at this. It’s too important to stop now.”

Coho show off their jumping skills, but they can’t swim up a pipe

Prompted by stream biologist Jon Oleyar. my grandson, Kevin Jeffries, and I visited Gorst Creek today during a break in the heavy rains.

As I reported in Water Ways yesterday, Jon, who counts salmon for the Suquamish Tribe, had observed an unusual number of coho salmon swimming upstream in Gorst Creek.

Because of heavy rains, the creek was running high and very fast this afternoon, and the waters were a muddy brown. In fact, the sediment load was so heavy that we spotted only a few fish swimming upstream. We suspected that a lot of them were hunkered down in deep pools, waiting for the flows to decline and the stream to become more passable.

Although we did not see a lot of fish, it was exciting to watch coho salmon trying to jump up into an outlet pipe that discharges water from the salmon-rearing raceways in the park. Coho, wearing their spawning colors of red, are known as jumping fish, but these guys were going nowhere fast. Check out the video on this page.

I’m looking forward to returning to the stream after the rains decline and the waters clear up a little bit. The coho may or may not be gone by then, but Jon expects that we should be able to see chum salmon in Gorst Creek at least until Christmas.

Coho salmon add to viewing experience in Gorst Creek

Gorst Creek is the place to go right now when looking for migrating salmon — not only chum but also coho, all decked out in their bright-red spawning colors, according to Jon Oleyar, who surveys East Kitsap streams for the Suquamish Tribe.

Jon called me last night with the news the coho, which adds some excitement to the salmon-watching experience.

Coho often hide along the stream edges, making them hard to spot. That’s why I generally focus the attention of salmon watchers on the more abundant chum, which race right up the middle of the streams. But it’s great when coho add themselves to the mix.

Jon reported that the coho can be seen easily in Gorst Creek at Otto Jarstad Park off Belfair Valley Road.

“There are a ton of fish in there,” he said, “and there are a lot of coho, bright red.”

He said there were also plenty of chum, some that have been in the stream awhile and others that have just arrived.

Bremerton Public Works officials, who manage the park, have not objected to people parking outside the park gate and walking into the park, where salmon-viewing platforms were built along the stream by the Kitsap Poggie Club.

One good spot, Jon said, is near a pipe where water from the nearby salmon-rearing operation pours out into the stream. Salmon seem to get confused and try to jump up into the pipe before heading on upstream.

Gorst Creek contains one of the latest chum runs on the Kitsap Peninsula, and people may be able to see salmon there until the end of the year. I often tell local residents that Jarstad Park is a good place to take out-of-town visitors during the holidays.

That’s especially the case this year, when the chum run in the Chico Creek system has basically run its course. The peak of the run typically comes at Thanksgiving, but this year it was about two weeks early, Jon tells me. While this year’s run was a decent size, he said, the stream right now is mostly a “smelly graveyard.”

“It is one of the earliest runs I’ve seen here,” he said of the Chico chum. “To have everything dead by Thanksgiving is very unusual.”

Another possibility for seeing salmon is Dogfish Creek, which runs through Poulsbo. “There might be a few stragglers in Dogfish Creek,” Jon said.

It’s not too late to take a look at any of the viewing spots listed on my salmon viewing map of the Kitsap Peninsula, but don’t go in with high hopes of seeing a lot of salmon at this time of year. Gorst, it appears, is the one sure bet at the moment. (The map also contains tips for observing salmon, which can be easily spooked.)

It’s worth noting that the rains this fall continue to be nearly ideal for the salmon, coming in with just enough intensity and frequency to keep the streams flowing at a good level without flooding. I covered this issue in Water Ways on Oct. 31.

“It has been perfect for salmon,” Jon told me yesterday. “Those early storms brought up the streams, and the fish that were coming in early had plenty of water.”

When the rains eventually dropped off, springs created by those rains kept the streams flowing until the next rains arrived. As a result, salmon were able to distribute themselves as far upstream as they could go. That does not happen every year.

A torrential downpour could still cause flooding and disrupt salmon eggs incubating in the gravel, but for now things look good on the Kitsap Peninsula.

As for total rainfall, we were on a record pace for the month of October across most of the Kitsap Peninsula, as I reported in Water Ways at the end of last month. But, as you can see from the charts below, we dropped off the record pace in early November but remain above average for the water year, which begins Oct. 1.

Happy Thanksgiving!

Amusing Monday:
Flying fish for increased survival, savings and fun

The “salmon cannon,” a pneumatic-tube device destined to replace some fish ladders, got plenty of serious attention this fall from various news organizations.

You may have seen demonstrations by the inventor, Whoosh Innovations of Bellevue, that showed adult salmon shooting unharmed through flexible tubes. For dramatic effect, some videos showed the salmon flying out the end of the tube and splashing into water. Among those who found the device amusing were commentators for “CBS This Morning” and “Red Eye” on Fox.

For a laugh, comedian John Oliver recently took the idea in a different direction, aiming his personal salmon cannon at celebrities including Jon Stuart, Jimmy Fallon and… Well, if you haven’t seen the video (above), I won’t spoil it for you.

All this attention has been a surprise for Vince Bryan, CEO for Whooshh, who told Vancouver Columbian reporter Eric Florip that he has spoken with hundreds of news organizations and potential customers from throughout the world.

“It was a nice boost because it says one thing, that people care a lot about the fish, and two, that there really is a need,” Bryan was quoted as saying.

A good description of the potential applications for the “salmon cannon” was written by reporter Laura Geggel of Live Science. Meanwhile, Reuters produced a nice animation showing how the tube works. And a video on the Whooshh Innovations YouTube channel, shown below, provides a clear demonstration how the transport system can work for both humans and fish.

Kitsap rains: not too much, not too little for salmon and aquifers

The on-and-off rains over the past two weeks are nearly perfect for both spawning salmon and for recharging shallow groundwater supplies, experts say.

For October, total rainfall ranges from about 5 inches at Hansville to 12 inches at Holly, according to rain gauges managed by the Kitsap Public Utility District. Fortunately, those rains have not been delivered to us in only a few days.

The intermittent nature of October rains has allowed the streams to maintain their flows without flooding. They’ve also allowed infiltration into the ground without excessive runoff.

“It is the good kind of rain,” said Bob Hunter, interim manager of Kitsap PUD. “We’ve had a couple of days when we’ve had 2-plus inches, but we haven’t seen the streams flash.”

In other words, the streams have not risen excessively fast. Bob attributes that to how dry the ground was before the rains began. Soils were able to absorb much of the early rainfall before stormwater runoff began to increase. Pauses between the rainstorms allowed more of the water to soak into the ground.

“It just goes to show you the variability that we have around here,” Bob told me.

October marks the beginning of the 2015 “water year.” Although we are just a month into the start of the year, the rainfall has been closely tracking all-time highs at some rain gauges — including Holly, which has been monitored since 1999. (See charts below.)

Meanwhile, the rain pattern in October was nearly perfect for salmon, said Jon Oleyar of the Suquamish Tribe, who walks the East Kitsap streams to count migrating salmon as they arrive.

“It seems like we’ve had storms coming in every couple of days, so they are not right on top of each other,” Jon said. “That gives the streams some time to recede.”

When there is not adequate flow, the salmon often wait for the streams to rise. On the other hand, too much flow can wash salmon eggs out of the streambed.

Last week’s rains got the chum salmon moving into most of the East Kitsap streams, Jon told me.

“I checked Chico Creek on Wednesday, and there were almost 11,000 fish in there and going up about as far as they can get,” he said.

A good escapement for the Chico Creek system is between 12,000 and 15,000 chum, and there is still more than a month left — assuming a typical timing of the run, he said. But things are looking a little different this year, he noted, and the bulk of the run may have arrived already.

One indication that timing could be different this year is that Gorst Creek already has a fair number of chum salmon — perhaps 500 — yet the Gorst Creek run usually comes in later and continues well into December.

Is it possible that all or most of the salmon runs are coming in early? It’s a question that only time will answer.

Jon told me that he’s a bit water-logged at the moment, trying to count fish in the rain with the streams running high.

“I’m pretty happy about it,” Jon said. “I have my fish up where they need to be, but it’s just hard to count them right now. If you’re a fish, this is really working for you.”

In the charts below, found on the Kitsap PUD’s website, you can see that October’s rainfall has been tracking the record high rainfall at these stations. Of course, the “water year” has barely begun, so anything can happen. (Click on images to enlarge.)
