Map of USGS gauge 07130500 and the river around it
Where ARKANSAS RIVER BELOW JOHN MARTIN RESERVOIR, CO. sits, with 2 other gauges on the same river and our water's map point.
Under CPW's 71°F line. Water 55.8°F now; the highest in the last 24 hours was 59.9°F. That is under the 71°F CPW uses for its closure criteria. “CPW recommends fishing early in the day to avoid peak afternoon temperatures.” “Anglers should use a handheld thermometer to test water conditions and move to cooler, higher-elevation waters once temperatures approach 71 degrees.”
Normal for Nov 5: 1.7–24 ft³/s (middle half of 78 years of record). Now: 2.51 ft³/s, normal.
Normal for this date. 2.51 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 78 years of record (1949–2026): 10th 1, 25th 1.7, median 4.2, 75th 24, 90th 69 ft³/s.
Daily means on record for Nov 5: lowest 0.6 ft³/s, highest 217 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).
Falling over 24 hours: discharge down 11.6%, from 2.84 to 2.51 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.
This gauge is on the same river as our page for Arkansas River, but no agency page we read lists its species.
Cold water. Water 55.8°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)Specific conductance 1,770 µS/cm at Nov 5, 9:00 PM MST; 7-day range 1,670–1,780 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.
The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
Checked Nov 5, 9:26 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.
