Map of USGS gauge 14243000 and the river around it
Where COWLITZ RIVER AT CASTLE ROCK, WA sits, with 1 other gauge 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.
This gauge is on the same river as our page for Cowlitz River, but no agency page we read lists its species.
Normal for Nov 5: 4,670–9,100 ft³/s (middle half of 99 years of record). Now: 4,250 ft³/s, below normal.
Below normal for this date. 4,250 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 99 years of record (1928–2026): 10th 2,960, 25th 4,670, median 6,690, 75th 9,100, 90th 13,000 ft³/s.
Daily means on record for Nov 5: lowest 1,110 ft³/s, highest 35,300 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% 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.
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)Turbidity 1.9 FNU at Nov 5, 7:20 PM PST; 7-day range 1.7–9.1 FNU
Water clarity: Turbidity measures the relative clarity of water: higher means murkier. No agency publishes a fishing threshold for it; compare with this gauge's own recent readings.
Turbidity and Water (U.S. Geological Survey)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 33.8 ft stage, 4,260 ft³/s at Nov 5, 6:30 PM PST (NWS gauge CASW1; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 3:02 PM PST. Highest point: 34.6 ft, 6,440 ft³/s on Nov 11, 4:00 AM PST (Below NWS action stage).
