Map of USGS gauge 14233500 and the river around it
Where COWLITZ RIVER NEAR KOSMOS, 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: 1,710–5,080 ft³/s (middle half of 78 years of record). Now: 363 ft³/s, lowest for this date on record.
Lowest for this date on record for this date. 363 ft³/s is below the lowest daily mean recorded on this date of daily mean flow for Nov 5 at this gauge over 78 years of record (1948–2025): 10th 1,230, 25th 1,710, median 2,870, 75th 5,080, 90th 7,650 ft³/s.
Daily means on record for Nov 5: lowest 424 ft³/s, highest 20,200 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 32.3%, from 536 to 363 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 Cowlitz River, 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.
