Map of USGS gauge 12181000 and the river around it
Where SKAGIT RIVER AT MARBLEMOUNT, WA sits, with 8 other gauges on the same river and our water's map point.
Normal for Nov 5: 4,270–8,560 ft³/s (middle half of 56 years of record). Now: 3,710 ft³/s, below normal.
Below normal for this date. 3,710 ft³/s is between the 10th and 25th percentiles of daily mean flow for Nov 5 at this gauge over 56 years of record (1944–2026): 10th 3,460, 25th 4,270, median 5,240, 75th 8,560, 90th 10,900 ft³/s.
Daily means on record for Nov 5: lowest 2,100 ft³/s, highest 20,800 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 (+4.5% 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.
Federal guidance. 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:
Under the federal 68°F line. Water 51.1°F now; the highest in the last 24 hours was 51.4°F. That is under the 68°F at which the National Park Service, at Grand Teton National Park, recommends anglers stop fishing in the afternoon (“cease fishing at 2 p.m. when water temperatures are likely to exceed 68°F”). Water warms through the afternoon, so check again later in the day: “Carry a pocket thermometer to monitor water temperature.”
High water temperatures prompt fishing advisory in Grand Teton National Park (29 July 2022) (National Park Service)This gauge is on the same river as our page for Skagit River, but no agency page we read lists its species.
Cold water. Water 51.1°F. NWS: “Cold shock can be just as severe and dangerous from water temperatures of 50-60°F (10-15°C) as it is from water at 35°F (2°C).” “Always wear a life jacket in and around the water.”
Cold Water Hazards and Safety (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.
