Map of USGS gauge 09073300 and the river around it
Where ROARING FORK RIVER AB DIFFICULT C NR ASPEN, CO. sits, with 4 other gauges 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 Colorado Parks and Wildlife uses are 71°F.
Normal for Nov 5: 13–21 ft³/s (middle half of 47 years of record). Now: 22.1 ft³/s, above normal.
Above normal for this date. 22.1 ft³/s is between the 75th and 90th percentiles of daily mean flow for Nov 5 at this gauge over 47 years of record (1980–2026): 10th 10, 25th 13, median 17, 75th 21, 90th 29 ft³/s.
Daily means on record for Nov 5: lowest 7.71 ft³/s, highest 54 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 (+6.8% 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 the agency lists for Roaring Fork River: Rainbow Trout, Brown Trout.

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)Specific conductance 79 µS/cm at Nov 1, 1:00 AM MDT; 7-day range 77–80 µS/cm; more than a day old
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.
NWS observed 1.24 ft stage, 22 ft³/s at Nov 5, 6:45 PM MST (NWS gauge RORC2; its stage datum can differ from the USGS gauge height).
NWS has not set flood categories for this gauge.
Graphical forecasts are not available during times of high water, forecast crest information can be found in the local WFO web page.
