Map of USGS gauge 12484500 and the river around it
Where YAKIMA RIVER AT UMTANUM, 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 our page for Yakima River, but no agency page we read lists its species.
Normal for Nov 5: 621–1,070 ft³/s (middle half of 93 years of record). Now: 639 ft³/s, normal.
Normal for this date. 639 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 93 years of record (1934–2026): 10th 455, 25th 621, median 883, 75th 1,070, 90th 1,800 ft³/s.
Daily means on record for Nov 5: lowest 351 ft³/s, highest 4,150 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 (+1.4% 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.

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 30.6 ft stage, 639 ft³/s at Nov 5, 7:15 PM PST (NWS gauge UMTW1; its stage datum can differ from the USGS gauge height).
NWS river forecast forecast issued Nov 5, 11:31 AM PST. Highest point: 30.7 ft, 682 ft³/s on Nov 14, 10:00 PM PST (Below NWS action stage).
