Planting Juvenile Coho in the Deschutes River

The Squaxin Island Tribe and the Washington Department of Fish teamed up this past June to release thousands of coho fry into Spurgeon Creek a tributary of the Deschutes River.

You can watch videos of the release here  and here

The Deschutes River system used to have a robust run of naturally spawning coho. This ended in the late 1980’s due to habitat degradation in coho spawning areas and decreases in marine survival along the entire west coast. Coho salmon generally spend 1.5 years in freshwater and 1.5 years in the ocean. This makes them especially vulnerable to changes in stream habitat and ocean conditions.

Coho salmon return to the stream they were born after three years. This means that a run of coho is made up of three different year classes or cohorts. In the late 1980’s one of these cohorts was considered essentially extinct because it was not producing enough fish to maintain the population. Starting in the mid 1990’s a second cohort also became functionally extinct.

Yearly plantings of juvenile coho will likely continue while in-river restoration and conservation projects are implemented and studies on the impacts of ocean conditions  such as the Salish Sea Marine Survival Project continue.

Conceptual design for the completed project.

The overall project involves-

Landowners: Simpson Lumber, Sierra Pacific Industries and the Port of Shelton.

Partners: South Puget Sound Salmon Enhancement Group, Mason Conservation District, Capitol Land Trust and the Squaxin Island Tribe.

Funding obtained to date has been provided by the Washington Department of Ecology National Coastal Wetlands Conservation Grant Program (information here) and the Salmon Recovery Funding Board (SRFB, information here). Significantly, all of the Lead Entities present in South Puget Sound contributed to the project enabling the SRFB to increase the amount of money available.

The project is large in scope and when complete will:

  • remove 811 creosote pilings
  • remove 1/2 mile of armored shoreline
  • remove 1/4 mile of inter-tidal dikes
  • restore 47 acres of saltmarsh
  • restore 1/2 mile of shoreline riparian
  • conserve 51 acres of tidelands and over 14 acres of riparian upland

The partners are currently in the permitting phase and anticipate construction to begin in the summer of 2017. To keep informed of the project status we have created a website sheltonharbor.org. Check in regularly for updates.

 

Collier Boat Ramp and Jetty Restoration

The Squaxin Island Tribe, working with our partner the South Puget Sound Salmon Enhancement Group http://spsseg.org/, recently completed a project to remove a boat ramp and large concrete structure that had  been used as a boat basin.

Both of these structures blocked the natural movement of sediment down the beach. Why is this important? This beach materiel is used by sand lance and surf smelt to lay their eggs. These, and other fish, are called Forage Fish because they provide a critically important food base for salmon and other creatures in Puget Sound. Blocking natural sediment movement causes the beach to cut down decreasing the available space for forage fish to spawn.

Before: Boat basin that had been used as a “dry dock” by the previous owner. This structure blocked sediment from moving down the beach.

The energy generated from waves breaking along the beach at an angle moves sand and sediment along the shoreline. We call areas where this happens over long stretches of beach Drift Cells as the sediment tends to drift or move in one direction. Structures located on the beach can block this sediment movement causing the beach to pile up on one side and down cut on the other.

In the early 2000’s the Tribe initiated a project to identify and rate beach sediment sources within Totten Inlet. The drift cell along the project area was found to be one of the longest in all of South Sound. This drift cell was rated as having a good sediment supply, called feeder bluffs as they feed sediment to the drift cells, and was found to be in generally good shape. Three structures were identified that blocked sediment movement down the beach. The first of these, the Arcadia Point boat launch, was fixed in 2011 when a solid concrete ramp was replaced with one that had channels that allow sediment to flow through.

The other two structures were the Collier boat ramp and jetty. Sediment can now move unimpeded on this over five mile long drift cell.

Each dock counts towards hurting salmon

OAQN7p copyHow much progress are we really making in restoring Puget Sound?

On one hand, community partners get together with us here at the tribe and at local governments to push forward a few habitat restoration projects a year. At the very most.

But, on the other end, dozens and dozens of shoreline development projects seem to sail through the local permitting process. Each of these projects is small on its own (a new bulkhead there, a dock here), so no one is bound to complain.

But, these tiny projects all put together are having a massive impact on Puget Sound, and its ability to produce salmon.

Nearshore habitat provides a critical nursery for juvenile salmon as they prepare to make their seaward migration, and also serves as migration corridors for returning adult salmon.

Here’s the short course on how these tiny developments can add up:

One way things like bulkheads and docks damage the environment is by disconnecting land and marine ecosystems. This disconnection prevents things like logs and bugs from entering and moving along the water, which ultimately alters the food chain and eliminates important habitat.

Another impact from shoreline modification is that it affects currents, which change where and how much sand is deposited. This in turn harms habitat of forage fish and invertebrates that are an important source of food for young and returning adult salmon.

But, I see dozens of these projects go through, with no mind paid to what the total impact of all the projects ever permitted is having.

Every letter we receive from Pierce County about yet another bulkhead or dock somewhere in Puget Sound includes language like this:

What does that mean in everyday language?

The County insists that this dock (or bulkhead on its own) isn’t a problem. But, they’re not going to actually look at its individual impact. Also they are not going to look at cumulative impacts to find out if this is the straw that breaks the camel’s back. Or, in this case, Puget Sound’s back.

And, what does that look like on the ground?

Here’s a visualization of Horsehead Bay (you can see a larger version here), which in its natural state would be great rearing habitat for juvenile salmon. But, when you add a few dozen docks, the value to salmon plummets.

Restoring Mission Creek At Priest Point Park

ThurstonTalk http://www.thurstontalk.com published a piece on a proposed restoration project in lower Budd Inlet.  As the article points out, cooperative projects that involve multiple agencies will be necessary to achieve recovery in Puget Sound.

By SarahJoy Smith

Priest Point Park is an oasis right at the edge of Olympia. The park is 341 acres in size, and boasts a full mile of shoreline right on Budd Bay. On a clear day you can stand at the shoreline and see a full view of the capitol rotunda in one direction, and the Olympic mountain range in its entire splendor in the other. But far more than just a beautiful view, Priest Point has much to offer its visitors in the way of outdoor fun as well.

As one of the largest within the city limits, the park offers a little something for everyone. Covered picnic facilities, complete with BBQ and outdoor “kitchen” amenities like running water, are available to the public for a reasonable fee. Many a gathering, graduation, and even the occasional wedding are held here. A formal rose garden is maintained in the spring and summer months that makes for a beautiful backdrop for such events.

Private and public organizations are joining forces to clean up Mission Creek.

Miles of trails meander through the wooded areas of the park, most of which provide relatively easy walks that even the smaller kids can do. But if the kids are less interested in walking there is always the large and inviting playground. Not to mention there is plenty of room to play by the water when the tide is out.

For the nature lover this is a wonderful place to observe wildlife. Heron, otter, eagle, seal, and even deer are some of the many wild residents seen daily by visitors.

This year, the park is getting some much needed restoration work to an area on the far eastern border known as Mission Creek. For centuries Mission Creek was a salmon run. Then sometime around 70 years ago it was paved over as a road.

Today all that remains is quite a bit of “rubble”, and a bulkhead which is acting as a block to salmon trying to enter the creek. The restoration will remove both rubble and a portion of the bulkhead. Then native vegetation will be replanted, invasive species removed, and some aesthetic changes will be made along the adjacent path to make it more welcoming for both people and salmon.

The restoration of Mission Creek has been a long time in the making. The main participants were proud to point out the joint effort between several different agencies. The Port of Olympia, City of Olympia, South Puget Sound Salmon Enhancement Group (SPSSEG), Squaxin Island Tribe, a funding group called Salmon Recovery Funding Board, and other agencies to a lesser extent have been working together for ten years to get approval for this restoration. As Lance Winecka, SPSSEG Executive Director pointed out, “It takes perseverance, but the take-home message is that we can work together with everyone to do what is right.”

The significance of the Mission Creek project is twofold. To begin with, at the completion of this project the entire shoreline of the park will have been restored to its natural state. Another bulkhead was actually removed at the opposite end of the park a few years back. But more importantly, this creek is the last remaining estuary within the area.

Restoration work at Mission Creek is returning the area to original habitat.

An estuary by definition is a place where salt water and fresh water meet. Throughout human history estuaries are the places that people live near because they provide many resources. As you can imagine the health of an estuary and the health of the people who live near that estuary are intertwined. Moreover, this restoration has the intended purpose of bringing the salmon back to an original spawning ground.

Salmon are an indicator species, which means that their presence or absence is a measure of how healthy a waterway is. When the salmon disappear it is a telltale sign that something is wrong with the natural balance of an area. Hence the reason this project was finally approved. Alex Smith, Senior Environmental Planning Manager for the Port of Olympia has been part of this effort for many years. “If (a site) has some kind of impairment, like Mission Creek does, it is a great candidate for funding because it can restore the salmon, which is good for all of us,” said Smith.

Her counterparts with the City and SPSSEG agree with this sentiment. David Hanna, Associate Director for City of Olympia Parks and Recreation department, feels that this is a win-win for salmon and people. “Doing as much as we can to restore an area, so long as it does not do damage to the relationship between the people and the park is important,” said Hanna. “Here we are returning a degraded system back to nature, and making the park better.”

If all continues to go according to plan the project is set to begin in late August and completed no later than September 15. The park will remain open during the restoration and is not anticipated to affect visitors, so be sure to make your way there. And by this fall with any luck you may even get to see some salmon in Mission Creek attempting to return to their long forgotten home.

Pesticides in Streams Harm Coho

One of the talks at the recent Salish Sea Ecosystem Conference showed how common household pesticides that are considered safe individually are lethal to juvenile coho when they are combined. The author found that the mixing of chemicals was either additive or synergistic meaning that the pesticides reacted with each other to become far more potent then if they were acting alone. Several mixtures that they looked at were found to be 100% lethal to coho.

Since 1996 the Environmental Protection Agency has mandated that chemical mixture testing be done for human health risks. However, in the aquatic environment the testing for chemicals is done only in isolation even though sampling of streams has shown that over 90% of the time multiple pesticides are found mixed together. Other studies have shown that coho essentially disappear from streams when the percent of impervious surface in the watershed reaches 10-15 percent. If legal and common household pesticides are part of this problem then recovering or protecting streams will be a much bigger challenge than previously thought.
