Streams

Streams are the life blood of island ecosystems and a major focus of our work. Our sole source aquifer feeds our streams and is our only source of clean fresh water so it is crucial that we steward our watersheds well.

SalmonWatchers

From September to January of each year, the salmon come home! Our SalmonWatcher volunteers, trained in salmon identification and monitoring protocols, regularly visit a specific spot on a local creek to record returning salmon. SalmonWatchers also help collect DNA from fish carcasses to help build a Salish Sea wide library of salmon genetic diversity and to record the types of salmon that call our streams home.

Salmonwatch volunteers can access all protocols and paperwork through the volunteer portal.

Trout Trackers

Following the salmon season, our creeks continue to teem with life, including trout! Coastal cutthroat trout are an integral part of stream networks and are abundant in island creeks, even more so than salmon. However, they’re often overlooked and understudied. To deepen our understanding of trout’s role and habitats in our local ecosystem, we launched a community science program called Trout Trackers in 2024. Volunteers survey the creek reaches weekly from February to May, documenting the presence of sea-run cutthroat trout. Check out below for insights from our first year of collecting quantitative data on spawning sea-run trout on the island.

Our Storm Water Action Group (SWAG) volunteers are trained to gather samples from salmon-bearing creeks during high water flows.

Stream Bugs

Aquatic macroinvertebrates (a.k.a. stream bugs) are sentinels of watershed health. Each fall, volunteers help us collect stream bug samples from island creeks.
