Map of USGS gauge 13010065 and the river around it
Where SNAKE RIVER AB JACKSON LAKE AT FLAGG RANCH WY sits, with 1 other gauge on the same river and our water's map point.
Under Wyoming's 65°F line. Water 47.3°F now; the highest in the last 24 hours was 47.7°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.”
Normal for Nov 5: 272–398 ft³/s (middle half of 43 years of record). Now: 281 ft³/s, normal.
Normal for this date. 281 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 43 years of record (1984–2026): 10th 227, 25th 272, median 322, 75th 398, 90th 527 ft³/s.
Daily means on record for Nov 5: lowest 207 ft³/s, highest 682 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 (−4.1% 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.
This gauge is on the same river as our page for Snake River, but no agency page we read lists its species.
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 47.3°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.
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 2.44 ft stage, 277 ft³/s at Nov 5, 8:30 PM MST (NWS gauge FLGW4; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 8:22 AM MST. Highest point: 2.46 ft, 285 ft³/s on Nov 5, 11:00 AM MST (Below NWS action stage).
