Good News: Big Hole River Trout Show Signs of Recovery, But Work Continues

Montana Fish, Wildlife & Parks (FWP) biologists are reporting some positive news for the Big Hole River. While trout populations remain below historic averages, recent sampling in two sections shows an increase in fish numbers compared to last year's record lows.

The Melrose and Hogback sections of the river saw rises in both rainbow and brown trout populations. Biologists attribute this improvement to good water levels in 2023, which likely aided the survival of young fish.

FWP fisheries biologist Jim Olsen remains cautious but optimistic.

“While trout populations are still well below the long-term average, this year’s estimates so far are encouraging,” Olsen said in a press release.

Sampling is ongoing in the remaining sections of the Big Hole (the Jerry Creek and Pennington sections), and results from other rivers in the upper Missouri River Basin are forthcoming.

This positive development comes alongside a new research effort launched by FWP and Montana State University. The partnership aims to understand the factors affecting trout decline in the Big Hole, Beaverhead, and Ruby rivers. Researchers are studying fish mortality, reproduction rates, and overall health.

Anglers can play a part in this effort by reporting any tagged fish they catch. This tagging program helps researchers track individual fish and monitor their well-being over time. Those who submit reports may also be eligible for rewards.

While there's still a way to go, the recent rise in trout numbers and the ongoing research collaboration offer hope for the future of the Big Hole River.
