Lagunitas Creek Restoration II

Restoration Stories

Each spring the Marin Municipal Water District (MMWD) operates a Rotary Screw Trap in lower Lagunitas Creek to count young salmon as they migrate to the ocean. The trap consists of a rotating cone that funnels fish into a live box, where every morning fish are counted, measured, and sent on their way. The fish seen in this video are mostly coho salmon smolts, but also include steelhead trout, Tomales roach, sculpin, three-spined stickleback, and likely a few Chinook salmon smolts. © Marin Municipal Water District
