Map of USGS gauge 11516530 and the river around it
Where KLAMATH R BL IRON GATE DAM CA sits, with 7 other gauges on the same river and our water's map point.
Normal for Nov 5: 1,060–1,773 ft³/s (middle half of 66 years of record). Now: 1,010 ft³/s, below normal.
Below normal for this date. 1,010 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 66 years of record: 10th 969, 25th 1,060, median 1,340, 75th 1,773, 90th 2,918 ft³/s.
Daily means on record for Nov 5: lowest 850 ft³/s, highest 4,730 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% 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.
No current water-temperature reading at this gauge, so no temperature guidance is given. Take a stream thermometer: the trout lines CDFW uses are 67°F.
