Map of USGS gauge 04137025 and the river around it
Where AU SABLE RIVER NEAR GLENNIE, MI sits, with 6 other gauges on the same river 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 53.8°F now; the highest in the last 24 hours was 54°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 Au Sable River, but no agency page we read lists its species.
Cold water. Water 53.8°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 10.2 mg/L at Nov 5, 8:45 PM EST; 7-day range 10.1–10.4 mg/L
Enough oxygen for coldwater fish: 10.2 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)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.
The National Weather Service has no flood-stage gauge here, so no official flood category is shown.
Checked Nov 5, 9:39 PM EST; readings refresh at most every 15 minutes and statistics daily. Provisional USGS data can be revised. Conditions change: re-check before you go. This is general guidance, not a fishing forecast, a safety guarantee or a statement about access.
