Local stewards
Groups already on this water system. The links go to how to show up, not a ranking, and not an endorsement of every program. This page is a starter list, not the full Support build.
The supply
Runs the Cedar River Watershed Habitat Conservation Plan, which marked its 25th anniversary in August 2025. That plan is a 50-year Endangered Species Act commitment, not a live gauge.
The fishery
Co-manages the Lake Washington sockeye fishery with WDFW, including the BLAST transport program. The Tribe’s 2024 Annual Report says more than 2,400 sockeye were transferred in 2024, the most recent publicly reported season, not a live count.
Instream flow
Administers WAC 173-508-060, the legally binding Cedar River instream-flow rule (370 cfs January through June, stepping down in summer), measured at the Renton gauge.
The sound
The state’s Puget Sound recovery agency. Its Leadership Council approved the 2026–2030 Action Agenda in June 2026, built with input from all 19 federally recognized Washington tribal governments.
The county
Runs a real hydrologic monitoring network in this county. Featured here as a steward to watch, not as a live feed on this site.
Eastside context
Serves Eastside suburbs (Bellevue, Redmond, and others), not Seattle itself. Useful for regional demand, not as a Seattle voice.
I build and maintain this site myself, in my free time. It is not affiliated with the groups or agencies named here.
I'm Rhett. I built this on my own so we can watch Seattle's two water sources in one place, without ads. If it is useful to you, a Ko-fi tip is optional and helps me keep the gauges running.
