Several of the small creeks around Tacoma have small populations of salmon. These are creeks that you can straddle. Examples include Puget Creek off Ruston Way, Swan Creek off Pioneer Way, and Hylebos Creek in Fife. I have seen chums spawning in all three in the fall and I know that coho have been observed in Puget Creek.
Some of these creeks have attracted dedicated advocates who work on habitat improvement and monitoring. Two examples are Puget Creek Restoration Society (http://www.pugetcreek.org/) and Friends of the Hylebos (https://www.earthcorps.org/our-story/hylebos/).
