Map of USGS gauge 14015000 and the river around it
Where MILL CREEK AT WALLA WALLA, WA sits, with 3 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. Washington Department of Fish and Wildlife publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Washington rule: 68°F.
Normal for Nov 5: 0.71–27 ft³/s (middle half of 85 years of record). Now: 20.4 ft³/s, normal.
Normal for this date. 20.4 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 85 years of record (1942–2026): 10th 0, 25th 0.71, median 6.1, 75th 27, 90th 57 ft³/s.
Daily means on record for Nov 5: lowest 0 ft³/s, highest 664 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 16.4%, from 24.4 to 20.4 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 our page for Mill Creek, but no agency page we read lists its species.
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.
