Warm water temperatures have triggered “hoot-owl” fishing restrictions, beginning Thursday, Aug. 3, on the Bitterroot River from Veterans Bridge on Highway 93 just north of Hamilton downstream to the confluence with the Clark Fork in Missoula (approximately 55 miles).
Hoot-owl restrictions close fishing from 2 p.m. to midnight.
The Bitterroot joins a portion of the Upper Clark Fork River and Silver Bow Creek that have been under the same restrictions since July 29.
Fishing is closed from 2 p.m. to midnight on the following rivers and streams in western Montana:
- Bitterroot (beginning Aug. 3): Veterans Bridge, downstream to confluence with Clark Fork (~55 miles)
- Upper Clark Fork: From headwaters at Warm Springs Ponds to Rock Creek (~100 miles)
- Silver Bow Creek: From the confluence with Blacktail Creek to where it enters Warm Springs Ponds.
“Although restriction criteria haven’t been met on other rivers, fish are feeling the impact of warming temperatures and lower flows across the region,” said Pat Saffel, FWP fisheries manager in Missoula. “Anglers can reduce stress on fish by limiting fishing to the cooler morning hours and if releasing fish, using proper techniques.”
FWP reminds anglers to wet hands before handling fish, remove the hook quickly and gently, and keep the fish in the water as much as possible.
The Blackfoot River has not reached the drought response triggers but has had warmer water temperatures as well. Anglers can help now by voluntarily fishing during the coolest hours of the day and using catch and release fishing techniques.
Some Blackfoot water right holders are or will soon be cutting back use as part of the Blackfoot’s “shared sacrifice” drought response, where anglers and irrigators work together to reduce stress on the fishery during critical periods.

FWP continues to monitor temperature, flows and fish mortality on rivers and streams and reevaluate the need for additional restrictions. For up-to-date information on restrictions related to drought across Montana, visit fwp.mt.gov/news/restrictions/.
