About the Hat Creek
Hat Creek occupies a particular place in American fly fishing. In 1968 the three and a half miles running from the Powerhouse 2 riffle down to Lake Britton were designated California’s first Wild Trout water, and the management ideas tested here spread across the western states. The creek rises in the volcanic highlands below Mount Lassen, gathers cold spring flow that runs at a nearly constant temperature year-round, and moves north in a broad, weedy, glass-smooth channel toward the Pit River.
The famous water is the Wild Trout section, and it is a true spring creek rather than a freestone. Flow barely varies. Weed beds grow thick through the summer and the current tongues between them are where fish hold. Rainbows here have seen every pattern in the catalogue and they feed with the deliberate, unhurried confidence of trout that are rarely surprised. Long fine leaders, drag-free drifts and a willingness to watch a fish for twenty minutes before casting are what separate good days from blank ones. There are browns in the mix, and they run larger and show themselves less.
Upstream of the Wild Trout water, the reach through the Hat Creek Park and Cassel area is a different and much friendlier fishery, with faster pocket water, planted and holdover rainbows and easier wading. Guides work both. This gauge sits on the upper creek near the town of Hat Creek and reports discharge, stage and water temperature. The temperature reading is the useful one on a spring creek, because it confirms the constant cold that makes the fishery work and flags the rare summer when it slips. Hatches are the calendar here: pale morning duns, the green drake in early summer and the evening caddis.
