Fishing closures are becoming routine as record heat warms rivers in the US West

Record summer heat and an exceptionally dry winter have driven water temperatures in rivers and streams across the U.S. West to lethal levels for trout. In response, wildlife officials are increasingly implementing routine fishing closures during certain hours to protect the fish populations that require cool water to survive.

The recurring restrictions reflect growing environmental strain on aquatic ecosystems in the region. As high temperatures and dry conditions persist, these regulatory measures are becoming a standard management tool for conservation authorities seeking to mitigate the impact of extreme weather on vulnerable wildlife.
