USGS gauges

Flow measured Aug 1, 2026, 6:00 PM UTC at gauge 01474000. Temperature measured Aug 1, 2026, 6:30 PM UTC at gauge 01473900. These are build-time snapshots, not a live feed — check the USGS gauge before relying on them.

This water was above the trout-stress threshold

Wissahickon Creek read 76.8°F as of Aug 1, 2026, 6:30 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.

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.
