What the agencies suggest

Stay low and approach slowly. Approach the stream carefully and with a low profile Iowa Department of Natural Resources
Work upstream. Fishing upstream will usually spook fewer fish than working downstream Iowa Department of Natural Resources
Look to deep pools and undercut banks. Deep pools and undercut banks provide refuge during sunny days and low water Minnesota Department of Natural Resources

General guidance from the readings and the published lines named above, not a fishing forecast. Local rules and closures come first.

Conditions for fishing general guidance

Water temperature for trout, salmon and steelhead

Under Montana FWP's 68°F line. Water 43.3°F now; the highest in the last 24 hours was 43.9°F. Montana FWP cites a study in which trout “caught and released from water with a temperature above 68 degrees F were far more likely to perish than those taken from cooler water.” Water warms through the day: “Fish in the cool morning hours.”
