Last updated 2026-09-24 · water classified by MDNR
MDNR types 17 named streams as cold water within 40 miles of Sturgis, Michigan — 44.6 miles of it inside that circle. The most of it is Mill Creek, 15.8 miles out, with 7.3 classified miles that MDNR types Cold stream. A thermal typing is MDNR's statement about the water, not a record of a fish in it and not permission to stand on the bank — check access and the current regulations before you go.
Ranked by how much classified water lies inside the circle, and by nothing else. Distance is a straight line to the nearest point of the stream rather than to its middle, because the question is how far you drive before you can park — this app carries no road network and will not print a drive time it cannot compute. A stream that runs out of the circle is counted for the part that is inside it, never for its whole length.
| Stream | Miles out | Classified miles | VSEC river type | Size | Thermal class |
|---|---|---|---|---|---|
| Mill Creek part of the stream | 15.8 | 7.3 | Cold stream | stream | 100% cold |
| Hayden Creek | 36.2 | 4.7 | Cold stream | stream | 100% cold |
| South Branch Paw Paw River | 34 | 4.4 | Cold stream | stream | 100% cold |
| Wilder Creek part of the stream | 39.1 | 4.1 | Cold transitional stream | stream | 100% cold-transitional |
| East Branch Paw Paw River | 30.5 | 4 | Cold stream | stream | 100% cold |
| Campbell Creek part of the stream | 38.6 | 3.7 | Cold stream | stream | 100% cold |
| Dowagiac Creek | 32.1 | 3.2 | Cold transitional stream | stream | 100% cold-transitional |
| Osborn Drain part of the stream | 37.5 | 2.8 | Cold transitional stream | stream | 100% cold-transitional |
17 named streams clear the circle in all and the 8 holding the most classified water are named. The rest carry less water than something a reader would pass on the way to it.
A stream marked part of the stream carries classified water outside the circle too, and the mileage here is only what is inside it. The thermal class is MDNR VSEC modelled thermal class, and it describes the reaches inside the circle rather than the whole stream.
Every row above is on the list because Michigan Department of Natural Resources publishes a modelled thermal class for every mapped reach (VSEC). That is MDNR's model of what the water does in summer — cold, which is where Michigan's trout are. It is a thermal typing rather than a designation; the regulation types that govern a Michigan trout stream are a separate table, on the state regulations page. It is not a record of a fish caught there, it is not a promise about any particular day, and it is not permission to walk to the bank — the land beside a classified stream can be private, and in most of these five states most of it is.
MDNR's own survey stations and stocking sites within 40 miles, counted. A survey is a fish somebody caught and counted; a stocking is a fish somebody put there. The count is of records, not of fish.
| Species | Surveys | Stockings | Latest |
|---|---|---|---|
| brown trout | 7 | 142 | 2026 |
| brook trout | 0 | 2 | 1996 |
Named public access standing on classified coldwater within 40 miles, nearest first. Each of these has a page of its own here, and that page says which list it came from — one of the five agencies, or OpenStreetMap, which is where most of the bridges and two-tracks a trout fisherman actually parks at are recorded. A site being on this list is not a claim about who owns the bank on either side of it, and the water named beside it is the classified reach the site stands nearest to rather than the one it is named for.
USGS gauges within 40 miles that report water temperature, nearest first. Federal rather than the state's, so one may stand across a state line. No reading is printed here — this page is about where the water is, and a temperature on it would be true only of the minute it was built. The river pages carry the live numbers.
