The trout water within 40 miles of Ontonagon

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.

149 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.

What MDNR is saying, and what it is not

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.

Getting to the water

This site has built access pages in Michigan and none of them stands within 40 miles of Ontonagon, so this page names none. Check MDNR for access, and read the boundary of any land you cross — a stream being classified says nothing about who owns the bank.

Thermometers in range

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.
