About this water

Foothill tailwater below Englebright Dam, drift-boat and walk-in water, holding hard-fighting wild rainbows. It also carries an ESA-listed wild steelhead run, so those fish get the gentle treatment they're owed. The signature event is the late-winter skwala stonefly — a big bug that gets the rainbows looking up when not much else is moving — and then PMD and caddis roll in as spring comes on. Flow leans on both releases and runoff, so it's worth a look before you load the boat.

  • Mixed
Conservation note

Holds ESA-listed Central Valley steelhead. These are wild fish carrying a hard story, so we name their presence and leave it at that — no catch score, no go-get-'em. Handle any you meet with real care.
