Conditions for fishing general guidance

Water temperature for trout, salmon and steelhead

Under Wyoming's 65°F line. Water 46.8°F now; the highest in the last 24 hours was 47.1°F. That is under the 65°F above which Wyoming Game and Fish suggests keeping trout rather than releasing them. Water warms by afternoon: “Water temperatures are coolest in the morning, giving released trout the best chance of survival.” “Carry a pocket thermometer to monitor the water temperature.”
