Fishing Report

Report conditions: 434 cfs · 59.9°F · ▼ 4.2% 24h · ↑2% median

Flows at Maiden Rock are sitting right at median and trending down slightly, with clear water and a cool 59.9°F reading this morning making for solid conditions. Note that the Big Hole has been under hoot owl restrictions as of late July, so plan to fish early and be off the water by 2pm. Mornings should see tricos and spruce moths bringing fish up, then switch to hoppers, Yellow Sallies, and ants through midday before the heat sets in. Nymph the deeper runs with attractor patterns and sow bugs early, then go all-in on terrestrials as the day warms.
