Map of USGS gauge 09010500 and the river around it
Where COLORADO RIVER BELOW BAKER GULCH NR GRAND LAKE, 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: 13–23 ft³/s (middle half of 73 years of record). Now: 12.6 ft³/s, below normal.
Below normal for this date. 12.6 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 73 years of record (1954–2026): 10th 9.9, 25th 13, median 16, 75th 23, 90th 33 ft³/s.
Daily means on record for Nov 5: lowest 7.3 ft³/s, highest 47.1 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 (−8.7% 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 our page for Colorado River, but no agency page we read lists its species.
