Free Grant Application Workshops for Community Watershed Stewardship Program

1 Comment | Add a Comment

Two upcoming workshops will take place January 7th and January 20th

Do you have an idea for a Community Watershed Stewardship Program (CWSP) grant project? Have you started the application paperwork, but don’t know what to write? Our friendly and helpful Student Coordinator is here to help you, and will be holding community workshops where you can get answers to your questions and information about how to make your grant as competitive as possible.

CWSP in action: volunteers from Depave remove pavement at St Mary's Ethiopian Orthodox Church to build a rain garden. Learn more here:

The deadline for submitting applications to the Community Watershed Stewardship (CWSP) grants is approaching fast. Pre-applications submitted by February 2nd will be reviewed and may be eligible for up to $10,000 to help Portlanders make improvements in their neighborhoods and communities, while also improving the health of our watersheds. You can learn all about CWSP here.

CWSP has two upcoming grant workshops that are fun, free and open to the public. Topics will include the grant selection process, criteria used for scoring applications and tips for giving your grant proposal its best chance at success. Successful grant proposals will promote equity and build community partnerships, and we can help you develop your ideas so they are reviewed competitively. Bring your friends, family, creativity, ideas and your love for our watersheds; we will provide everything else! Refreshments will be provided, free of charge.

The dates, times and locations for the two upcoming January workshops are: 

  • Sunday, January 7th from 1:30 to 2:30 p.m. at the Woodstock Library, located at 6008 SE 49th Ave, Portland OR 97206
  • Saturday, January 20th from 12:45 to 1:45 pm at the Holgate Library, located at 7905 SE Holgate Blvd, Portland, OR 97206

Questions about CWSP and the grant writing workshops can be sent to CWSP Grants Coordinator, B Castra Nemici,  at or by phone at 503-823-7917.

Nature in the city: Can trout and salmon thrive in Tryon Creek? New study is encouraging.

2 Comments | Add a Comment

Tryon Creek is one of the major remaining free-flowing tributaries of the Lower Willamette River. New research shows just how healthy it is for cutthroat trout, and that’s important for the future of trout as well as for prospects to restore salmon to Tryon Creek.

Tryon Creek is one of the major remaining free-flowing tributaries of the Lower Willamette River. New research shows just how healthy it is for cutthroat trout, and that’s important for the future of trout as well as for prospects to restore salmon to Tryon Creek.

The primary obstacle to restoring salmon to the urban watershed is a 400-foot culvert underneath Highway 43 near the confluence with the Willamette River.  A conduit for water, it is a barrier for fish. Environmental Services, in concert with partners including the US Army Corps of Engineers have plans to remove that culvert and replace it with a wider, shallower passageway that will allow native and migratory fish like salmon and lamprey to reach the cool clean waters of Tryon Creek – and the high quality spawning and rearing habitat the creek offers.

Biologists use a seine net to survey fish below the Highway 43 culvert of Tryon Creek.

Now the new study adds to the body of knowledge showing just how healthy Tryon Creek habitat is for fish. Published in the journal Urban Ecosystems by Environmental Services scientist Melissa Brown and colleagues at the US Fish and Wildlife Service, the research compares the health of urban trout in Tryon Creek to non-urban populations elsewhere in the region. The findings show that the health of coastal cutthroat trout in this urban waterway is comparable to that of cutthroat trout in 35 more pristine rivers and streams throughout the Columbia River basin and northern California. That research tells us that there is carrying capacity in the stream for migratory salmon, such as chinook, coho and steelhead trout, says Brown.

A cutthroat trout is measured to help biologists assess the fish population's health.

As for plans to remove the Highway 43 culvert and replace it with a better passageway: Congress authorized funding for it and additional Healthy Willamette River projects last session as part of a package sponsored by the US Army Corps of Engineers. Next steps, which are underway, call for Congress to allocate the dollars that would allow the package of restoration projects to be realized.

Environmental Services is looking forward to working with the US Fish and Wildlife Services again to assess population dynamics in the future after native, migratory fish start returning to historic habitat once a new Highway 43 passage is built.

P.S. The Tryon Creek watershed is closed to fishing.

The collection features the beauty of green infrastructure and is showing at St Johns Community Center and Charles Jordan Community Center

The Art of Stormwater, a collection of artistic photographs of green infrastructure around the city, is currently being displayed at the St. Johns Community Center (8427 N Central St) and the Charles Jordan Community Center (9009 N Foss Ave) in North Portland.

The collection shows the beauty of green infrastructure techniques that are designed to soak up stormwater, reduce flooding, filter pollutants, and ensure clean rivers. The exhibits will be up until December 28th in St. Johns and until mid-January at the Charles Jordan Community Center.
