60 mapped river miles, draining 362 square miles across Arenac, Ogemaw counties, in the Au Gres-Rifle subbasin watershed. 1 USGS gauge report water temperature on it, and this page reads it.

Water temperature — the colour of the river, and of every dot on it

50°F and colder is cold, through cold-transitional and cool, to warm above 70°F — the same four bands, breaking at 58, 64 and 70°F, that the app paints. Grey is water nobody has measured.

Water temperature right now

Live from the USGS — every pill above is live, so the numbers you are reading are the latest continuous readings at each gauge. Provisional and unreviewed, as all real-time data is. If that fetch cannot happen — you are offline, or the USGS is down — the pills fall back to the last value we cached, 30 September 2026, 13:43 UTC. None of them, in fact: Sterling is not reporting water temperature — it has sent no water temperature for 720 days, since 8 October 2024. That pill carries a modelled temperature where one can be fitted, marked as modelled, and a dash where it cannot — never a stale reading dressed as a current one.

The character of the water

Temperature here rests on a gauge rather than a valley class. Rifle River near Sterling sits at river mile 4.9, covering a 54.9-mile reach, with a July mean of 71.7 F, a July range of 13.5 F and an uncertainty of 1.98 F over six Julys from 2019 through 2024; groundwater input is rated low. The gauge sits at the downstream end of its reach, so that mean stands for the warmest water in it and everything above runs colder. Type 3 regulations cover 54.1 of the 59.9 mapped miles, January 1st through December 31st, with Type 1 on 6.1 miles and a creel of five fish, no more than three 15 inches or greater. Median width is 40.7 feet on a fifth-order drainage of 362.47 square miles across Arenac and Ogemaw counties. Brown and rainbow trout stocking continues through 2026, heaviest at State Road - Selkirk at 25,311.8 per mile. Nineteen public units total 62,394 acres, with 13 access sites and 12 launches.

Thermal classification

Each gauge carries a July mean built from its own daily record — 6 Julys, 2019–2024, measured rather than modelled. A July mean is what decides which of the four bands a stretch of water belongs to, because July is when a trout river either holds or does not.

Reach July mean Band Groundwater
Sterling
RM 59.9–4.9
71.7 °F warm low

Every gauge sits at the bottom of its segment, so each number is the warm end and the water above it runs colder. ±1.98 °F on the fit.

The lake run

The Rifle River is a Lake Huron tributary with 55.0 miles of run corridor on it — salmon, steelhead and lake-run brown trout, on their own calendar and under their own rules. Run timing, species and access on the Rifle River →

Fishable reaches

River miles are measured above the mouth, along the mapped mainstem. The reach breaks are the gauges, which is also how the temperature model divides the river.

Hatches on this water

53 insects are recorded from northern lower Michigan, which is the region this river sits in. That is a claim about the region and not a survey of this stream: nobody has recorded which of them has been caught here. Open the river in the app and the hatch panel will narrow it to the ones whose temperature window today's reading is inside.

Tributaries and watershed

25 named streams meet this one. Confluence miles are above the mouth; the longest twelve are listed.

Rifle River sits in HUC 8 04080101, the Au Gres-Rifle subbasin, and drains 362 square miles, Strahler order 5 at the mouth. 115 NHD reaches carry the name for 68.0 miles in total — more than the 59.9 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
