Rising water temperatures in Montana are prompting hoot-owl fishing restrictions from 2 p.m. to midnight to protect fish populations. Effective July 22, the restrictions affect several rivers, including the Big Hole and Yellowstone. These measures aim to mitigate stress due to high temperatures and low flows, ensuring fish health and sustainability.

In southwest Montana, warming river temperatures are leading to increased fishing restrictions. The Madison River is completely closed to fishing from July 15, and hoot-owl restrictions apply to several rivers, prohibiting fishing from 2 p.m. to midnight. These measures aim to protect fish as high temperatures can cause stress and mortality.
