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

Record-breaking summer heat across the U.S. West has raised river temperatures to levels that threaten the survival of trout populations. In response to these environmental conditions, wildlife officials have implemented mandatory fishing closures during specific hours on various rivers and streams throughout the region.

These restrictions are increasingly becoming a routine management tool as authorities attempt to mitigate heat-related fish mortality. By limiting angling activity during the hottest parts of the day, officials aim to reduce stress on fish already struggling to survive in warming waters.
