Map of USGS gauge 09216050 and the river around it
Where Big Sandy River at Gasson Bridge, near Eden, WY sits, with 1 other gauge on the same river and our water's map point.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines Wyoming Game and Fish uses are 65°F, 68°F and 70°F.
Species the agency lists for Big Sandy River: Bear River Cutthroat, Brook Trout, Brown Trout, Rainbow Trout, Snake River Cutthroat.
Normal for Nov 5: 43–63 ft³/s (middle half of 34 years of record). Now: 52.3 ft³/s, normal.
Normal for this date. 52.3 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 34 years of record (1973–2006): 10th 29, 25th 43, median 55, 75th 63, 90th 80 ft³/s.
Daily means on record for Nov 5: lowest 17 ft³/s, highest 340 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 (+1.9% 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.
Source: Yellow streams (WGFD stream classification: Yellow, 50-299 lbs trout/mile) (Wyoming Game and Fish Department).
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, 7:48 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.
