Map of USGS gauge 14238000 and the river around it
Where COWLITZ RIVER BELOW MAYFIELD DAM, WA sits, with 2 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: 3,540–6,500 ft³/s (middle half of 92 years of record). Now: 3,560 ft³/s, normal.
Normal for this date. 3,560 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 92 years of record (1935–2026): 10th 2,210, 25th 3,540, median 4,710, 75th 6,500, 90th 9,050 ft³/s.
Daily means on record for Nov 5: lowest 890 ft³/s, highest 25,000 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 (−0.3% 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 Cowlitz River, but no agency page we read lists its species.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
Flood categories: action stage, minor, moderate and major flooding (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)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.
Below NWS action stage. The National Weather Service reports this gauge below its action stage. That is not a statement that wading is safe.
NWS observed 10.6 ft³/s at Nov 5, 5:00 PM PST (NWS gauge MAYW1; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 3:02 PM PST. Highest point: 10.6 ft³/s on Nov 5, 4:00 PM PST (Below NWS action stage).
