Map of USGS gauge 04135700 and the river around it
Where SOUTH BRANCH AU SABLE RIVER NEAR LUZERNE, MI sits and our water's map point.
Federal guidance. Michigan 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 Michigan rule:
Under the federal 68°F line. Water 52°F now; the highest in the last 24 hours was 55°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: 166–250 ft³/s (middle half of 59 years of record). Now: 175 ft³/s, normal.
Normal for this date. 175 ft³/s is between the 25th and 75th percentiles of daily mean flow for Nov 5 at this gauge over 59 years of record (1967–2026): 10th 136, 25th 166, median 211, 75th 250, 90th 323 ft³/s.
Daily means on record for Nov 5: lowest 110 ft³/s, highest 565 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 (+1.7% 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 South Branch Au Sable River, but no agency page we read lists its species.
Cold water. Water 52°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)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.
NWS observation not current. NWS has no current observation at this gauge, so no flood category is shown.
NWS has not set flood categories for this gauge.
Forecasts are not available. Only observed stages are available for this point.
