Map of USGS gauge 12323233 and the river around it
Where Blacktail Creek above Grove Gulch, at Butte, MT sits.
Under Montana FWP's 68°F line. Water 42.1°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.”
“Giving a hoot”, Montana Outdoors (July–August 2024) (Montana Fish, Wildlife & Parks)USGS publishes no daily statistics for this gauge, so the reading is not compared with the record.
Falling over 24 hours: discharge down 37.2%, from 5.81 to 3.65 ft³/s. Rising or falling means a change of more than 10% in discharge (or 0.2 ft of gauge height) over 24 hours; our rule of thumb, not a USGS class.
Species list not on file for this gauge. Check the Montana Fish, Wildlife & Parks: Montana fish stocking data · Montana fishing regulations.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
Flood categories: action stage, minor, moderate and major flooding (National Weather Service)Cold water. Water 42.1°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.
Turn Around Don't Drown (National Weather Service)Turbidity 11.6 FNU at Nov 5, 8:30 PM MST; 7-day range 2.8–49.1 FNU
Water clarity: Turbidity measures the relative clarity of water: higher means murkier. No agency publishes a fishing threshold for it; compare with this gauge's own recent readings.
Turbidity and Water (U.S. Geological Survey)Specific conductance 380 µS/cm at Nov 5, 8:30 PM MST; 7-day range 283–412 µS/cm
Dissolved ions: Specific conductance rises with the ions dissolved in the water. No fishing threshold is published for it; compare with this gauge's own recent readings.
Conductivity (Electrical Conductance) and Water (U.S. Geological Survey)Guidance from the readings above and the published thresholds named with each line; not a fishing forecast, a safety guarantee or a statement about access. Local rules and closures come first.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
NWS observed 4.46 ft stage at Nov 5, 7:30 PM MST (NWS gauge BKCM8; its stage datum can differ from the USGS gauge height).
Graphical forecasts are not available during times of high water, forecast crest information can be found in the local WFO web page.
