Map of USGS gauge 04024000 and the river around it
Where ST. LOUIS RIVER AT SCANLON, MN sits and our water's map point.
Federal guidance. Minnesota DNR publishes no water-temperature line for trout anglers that we found. The lines below are the National Park Service's, federal guidance, not a Minnesota rule, with Minnesota DNR's own figure added:
Under the federal 68°F line. Water 49.3°F now; the highest in the last 24 hours was 51.3°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.”
Normal for Nov 5: 978–2,320 ft³/s (middle half of 118 years of record). Now: 7,670 ft³/s, much above normal.
Much above normal for this date. 7,670 ft³/s is above the 90th percentile of daily mean flow for Nov 5 at this gauge over 118 years of record (1909–2026): 10th 649, 25th 978, median 1,340, 75th 2,320, 90th 3,170 ft³/s.
Daily means on record for Nov 5: lowest 405 ft³/s, highest 13,200 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).
Rising over 24 hours: discharge up 49.5%, from 5,130 to 7,670 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 Saint Louis 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)Rising water. Rising over the last 24 hours (discharge up 49.5%). Keep your way back to the bank in sight and watch the level while you fish. “Rising” is our rule of thumb: more than 10% in discharge or 0.2 ft of gauge height in 24 hours, not a USGS or NWS class.
Flow far above normal. Above the 90th percentile of daily mean flow for this date (USGS class “much above normal”), from 118 years of record. Expect higher, faster water than usual for the season.
hyswap: flow categories (WDFN_stats schema) (U.S. Geological Survey) Statistics documentation (percentiles of daily mean discharge) (U.S. Geological Survey)Cold water. Water 49.3°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.
Turn Around Don't Drown (National Weather Service)Dissolved oxygen 11.3 mg/L at Nov 5, 8:00 PM CST; 7-day range 10.7–11.3 mg/L
Enough oxygen for coldwater fish: 11.3 mg/L meets the 6.5 mg/L EPA sets for coldwater fish (other life stages; eggs and fry need a 8 mg/L minimum).
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)pH 7.8 at Nov 5, 8:00 PM CST; 7-day range 7.8–8.2
Within EPA's freshwater range: pH 7.8 is within the 6.5–9 range EPA gives for freshwater aquatic life.
Quality Criteria for Water 1986 (“Gold Book”): dissolved oxygen, Table 1; pH (U.S. Environmental Protection Agency)Turbidity 27.2 FNU at Nov 5, 8:00 PM CST; 7-day range 2.3–27.2 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)Specific conductance 231 µS/cm at Nov 5, 8:00 PM CST; 7-day range 231–353 µS/cm
Dissolved ions: Specific conductance rises with the ions dissolved in the water. No fishing threshold is published for it; compare with this gauge's own recent readings.
Conductivity (Electrical Conductance) 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 6.84 ft stage, 7,670 ft³/s at Nov 5, 7:30 PM CST (NWS gauge SCNM5; its stage datum can differ from the USGS gauge height).
Forecasts are issued as needed during times of high water, but are not routinely available.
