This water was above the trout-stress threshold
Casselman River read 75.4°F as of Aug 1, 2026, 12:30 PM CDT. 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.
At or above that threshold many anglers stop fishing for the day, fish early morning only, or move to colder water. We are reporting a measurement, not issuing an advisory — check your state agency for any restriction actually in force.
