Map of USGS gauge 12323720 and the river around it
Where Willow Creek at Opportunity, MT sits, with 1 other gauge on the same river.
Under Montana FWP's 68°F line. Water 41.9°F now; the highest in the last 24 hours was 43.7°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)Normal for Nov 5: 5.1–7.5 ft³/s (middle half of 23 years of record). Now: 4.27 ft³/s, much below normal.
Much below normal for this date. 4.27 ft³/s is below the 10th percentile of daily mean flow for Nov 5 at this gauge over 23 years of record (2004–2026): 10th 4.6, 25th 5.1, median 6.4, 75th 7.5, 90th 9.9 ft³/s.
Daily means on record for Nov 5: lowest 4.04 ft³/s, highest 10.7 ft³/s.
Classes as USGS labels them (hyswap: flow categories (WDFN_stats schema) (U.S. Geological Survey) ); percentiles from the USGS daily statistics (U.S. Geological Survey) (approved daily means; the reading is provisional and instantaneous).
Steady over 24 hours (−6.4% discharge). 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.
Cold water. Water 41.9°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.
Turn Around Don't Drown (National Weather Service)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.
The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
Checked Nov 5, 7:54 PM MST; readings refresh at most every 15 minutes and statistics daily. Provisional USGS data can be revised. Conditions change: re-check before you go. This is general guidance, not a fishing forecast, a safety guarantee or a statement about access.
