16.1 mapped river miles, draining 50 square miles, in the Au Gres-Rifle subbasin watershed. No gauge stands in it; the nearest is 11.8 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 19.7 miles away, at Au Sable River — not a reading of this water, but of what the region is doing today. A closer gauge has stopped reporting — it has sent no water temperature for 720 days, since 8 October 2024, so no number here comes from it.
Sixteen and one-tenth miles of Johnson Creek are mapped in the Au Gres-Rifle subbasin, matching 16.09 miles in the NHD, a medium stream of 12.2 feet median width draining 49.56 square miles at Strahler order 4. Type 1 regulations cover 11.4 miles: open from the last Saturday in April through September 30th, artificial lures and all types of natural bait permitted, and a creel of 5 fish with no more than 3 trout 15" or greater and zero Arctic Grayling. MDNR types 5.9 miles, 37 percent of the length, from river mile 16.1 down to 8.6 as Cool, a warm transitional stream on medium gradient. That class describes the valley segment, not the water, and no measured temperature exists; the nearest gauge, Rifle River near Sterling, lies 11.8 miles off. Three public land units total 33,263 acres, led by the Au Sable State Forest Gladwin Unit at 33,124. No access sites, walk-in access, 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.
| Reach | Typed miles | Band | MDNR type |

| RM 16.1–8.6 | 5.9 | cool | Warm transitional stream · medium gradient |
MDNR has classified 5.9 of the 16.1 miles NHD carries for this stream — 37% 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 11.4 of the 16.1 mapped miles; 4.7 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.
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.
