Map of USGS gauge 06026420 and the river around it
Where Big Hole R bl Hamilton Ditch nr Twin Bridges, MT sits, with 3 other gauges on the same river and our water's map point.
Not compared with the record because the reading is old.
Under Montana FWP's 68°F line. Water 41°F now; the highest in the last 24 hours was 41.9°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.”

Cold water. Water 41°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.”
