Hatch Status

Caddis have been coming off every evening

Conditions

The Kootenai is firing on all cylinders with big foam attractors and nymphs working 2-3 feet below the surface. Grasshoppers are abundant and effective, and evening caddis are providing a solid hatch window. Expect to find rainbows, cutthroats, bull trout, and the occasional brown in the 12-16 inch range. As of August 7, flows were stable at 9,640 CFS at Leonia with water temperatures around 59°F, creating prime late-summer conditions.

Gauges

Techniques

  • Big foam flies still working good, like Henneberry Hoppers, Chubbies, Plan B's, or any other big foam attractor with a nymph below about 2'-3' down
