17.9 mapped river miles, draining 280 square miles, in the Au Sable River watershed. No gauge stands in it; the nearest is 11.1 miles away, and what this page knows about its temperature is MDNR's classification of the water itself.
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.
The nearest gauge is 11.1 miles away, at Au Sable River Near Au Sable — not a reading of this water, but of what the region is doing today.
Draining 279.95 square miles into the Au Sable River watershed, this is a fifth-order river by Strahler ordering, though the channel itself stays modest: a median width of 13.9 feet across 17.9 mapped miles, with the NHD network putting the total at 20.77 miles. MDNR has typed 10.0 of those miles, 48 percent of the mapped length, running from river mile 17.9 down to the mouth, and classes that whole span as warm stream with high gradient. Because the classification describes the valley segment rather than the water, no measured temperature exists here; the nearest gauge, on the Au Sable River near Au Sable, sits 11.1 miles off. The Pine River joins at river mile 0.0 after 11.8 miles of its own. Public land is essentially one holding: 89,736 acres across two units, of which the Au Sable State Forest Grayling Unit accounts for 89,732 and Van Etten Creek Park for 4. No access sites, walk-in areas, or launches are recorded.
MDNR types this water from its valley, not from a thermometer in it. A class, not a temperature — no July mean, because none was measured here.

MDNR has classified 10.0 of the 21 miles NHD carries for this stream — 48% of it. Every typed reach carries the same class, warm. The untyped reaches are not warm water — they are water MDNR's inventory does not reach, and the mile ranges above span only the reaches it does.
2 units of public or open-access land touch this river, 89,736 acres in total. Acreage is the whole unit, not the part beside the water.

No species records for this water in the files this site reads.
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.

1 named stream meets this one. Confluence miles are above the mouth; the longest twelve are listed.
Van Etten Creek sits in HUC 8 04070007, the Au Sable River watershed, and drains 280 square miles, Strahler order 5 at the mouth. 24 NHD reaches carry the name for 20.8 miles in total — more than the 17.9 miles of drawn mainstem, because NHD counts side channels and braids as their own reaches.
