SAVE WILD TROUT: WHAT THE DATA ARE TELLING US ABOUT THE JEFFERSON BASIN

This Thursday, January 8, Save Wild Trout will host a public briefing in Helena examining new water-quality data from across the Jefferson Basin—home to some of Montana’s most iconic cold-water fisheries.

Program Director Brian Wheeler will share findings from Save Wild Trout’s basin-wide monitoring work, including trends in water temperature, nutrients, dissolved oxygen, and algae that directly affect wild trout survival in the Big Hole, Beaverhead, Ruby, Jefferson, and Boulder rivers.

Keynote Event to include release of comprehensive report of river health in Jefferson Basin, July 14

Save Wild Trout is hosting a keynote unveiling of the “Jefferson River Basin Abiotic Monitoring 2023–2024” report—an unprecedented study integrating drone-based thermal (FLIR) imaging, in-stream water quality sampling, and extensive on-the-ground monitoring. The event connects the public directly with the scientist and advocates leading the charge to protect Montana’s cold water rivers, wild trout, and the economy they support. Hands-on activities for all ages and an open house precede the main presentation.

Save Wild Trout Captures Early Algae Bloom With Aerial Photography on Big Hole River; Jefferson Basin Report To Be Released On July 14

Save Wild Trout (SWT) continues its 2025 field season with expanded water quality monitoring across the Jefferson Basin, building on years of science-based advocacy to protect Montana’s rivers. This weekend, that work was complemented by aerial photography documenting an early-season algae bloom on the lower Big Hole River—part of a troubling trend first reported by SWT in late June across the Big Hole, Jefferson, and Boulder Rivers.
