Map of USGS gauge 13011820 and the river around it
Where Blackrock Cr bl Split Rock Cr, nr Moran, WY sits.
Under Wyoming's 65°F line. Water 34.9°F now; the highest in the last 24 hours was 36.1°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.”
Fishing in the heat (Wyoming Game and Fish Department)Species list not on file for this gauge. Check the Wyoming Game and Fish Department: Wyoming fish stocking report · Wyoming fishing regulations.
Cold water. Water 34.9°F. NWS: “Cold shock can be just as severe and dangerous from water temperatures of 50-60°F (10-15°C) as it is from water at 35°F (2°C).” “Always wear a life jacket in and around the water.”
Cold Water Hazards and Safety (National Weather Service)Turn Around Don't Drown. “A mere 6 inches of fast-moving flood water can knock over an adult.” No flow number makes a crossing safe; if in doubt, stay out.
