I learned about a new creek in the last month…. With stunning potential!
Percival Creek. A local treasure!
I have driven past its mouth a thousand times:
Driving along Capitol Lake, cross the bumpy train tracks at Marathon Park. Look southwest over the water to the forest. There, Percival Creek enters the cove on Capitol Lake. Historically, steelhead, coho and chinook salmon in fall swam up the stream in that canyon adjoining the railroad tracks, and swam under Cooper Point Road and Highway 101 to reach a fork. Some fish may have gone right towards Black Lake. Fish going left swam past the Hoh Brewery and South Puget Sound Community College. Then onward through the pipe at Sapp Road and Trosper Road and onto Trosper Lake.

The 1986 Thurston Regional Planning Council Percival Creek Corridor Plan shares:
“Percival Creek supports both salmon and steelhead spawning in the 1970s” (page 37) |
Interpretive maps near a trail where Sapp road crosses Percival Creek may answer some of your questions.
Mapping of the Black Lake area claimed the area for people. But what did they see in the 1850s?
Time travel! Find Black Lake, Percival Creek, Deschutes River and the swamp on both maps.
The swamp and environs not only supports a rare bog, streamflows for salmon and possibly drinking water of the lower Deschutes, but also the only known Oregon spotted frogs surviving in a Urban Growth Area. Can both humans and wildlife survive in a UGA? Time will tell.
