Water temperature and trout

Little Mahoning Creek read 66.4°F as of Aug 1, 2026, 6:00 PM UTC. Trout come under thermal stress above roughly 68°F, and mortality after catch-and-release rises sharply in warm water. Montana FWP restricts angling when max daily water temperature reaches 73F for 3 consecutive days.

This reading sat below the stress threshold. Temperatures swing through the day and peak in late afternoon, so a morning reading can understate the daily maximum.
