41 mapped river miles, draining 252 square miles, in the Black-Presque Isle subbasin watershed. No gauge stands in it; the nearest is 15.7 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 15.7 miles away, at Presque Isle River — not a reading of this water, but of what the region is doing today.
The Black River is the longest water in this set, 41.1 mapped miles in the Black-Presque Isle subbasin matching 41.11 in the NHD, 25.9 feet wide at the median and draining 251.81 square miles at Strahler order 5. Three regulation types divide it: 15.9 miles of Type 1 and 21.4 miles of Type 2, both open the last Saturday in April through September 30th, and 0.7 miles of Type 3 open January 1st through December 31st, all allowing artificial lures and natural bait under a 5 fish creel with no more than 3 trout 15" or greater. MDNR types 16.1 miles, 39 percent, as Cool from river mile 38.1 to 1.1, a warm transitional stream on high gradient; no measured temperature exists, and the Presque Isle River gauge is 15.7 miles off. Eight public land units total 82,000 acres, including 4,302 acres of Black, Michigan Wild and Scenic River. No access sites or launches are listed.
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.
| Reach | Typed miles | Band | MDNR type |

MDNR has classified 16.1 of the 41 miles NHD carries for this stream — 39% of it. Every typed reach carries the same class, cool. 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.
MDNR trout stream types, as designated. Types on file cover 38.0 of the 41.1 mapped miles; 3.1 miles carry no type in this dataset. Always check the current Michigan Fishing Guide before you fish — this is a copy, and the Guide is the rule.

No species records for this water in the files this site reads.
42 insects are recorded from the Upper Peninsula, 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.
