Fishing Report

Report conditions: 27 cfs · 57.9°F · ▼ 11.4% 24h · ↓41% median

Flows at Wisdom are way down at 27.2 cfs, 41% below median and still trending down over the last 24 hours—this is low, thin water so expect spooky fish and long, light leaders. Water temp at 57.9°F this morning is in good shape, but with clear skies and no cloud cover, get on the water early for tricos and be off by early afternoon as temps climb. No hoot owl restrictions currently on this upper stretch, but given the drought-low flows and shop reports of restrictions creeping in downstream, fish it respectfully and expect changes soon. Focus on trico spinner falls and midges at first light, then switch to hoppers, ants, and beetles along grassy banks as the sun gets higher.
