BirdTroutOpen the map Is the Little Elk River good for brook trout?
Yes, on the classification rather than on a thermometer. WDNR has stocked brook trout into the Little Elk River across 2 recorded plants, between 2020 and 2022, and this site reads the water as cool from WDNR's management tier for it, which is an inference from how the fishery is managed and not a temperature WDNR publishes — but no USGS gauge on this river reports water temperature, so this site has no measured July mean to hold against the 53–61 °F band this fish wants. That is a stocking record and not a survey: it says WDNR put the fish in, not that anyone has since found one holding over. Fish of 6–11 inches are what Wisconsin reports as typical.

- stocked — no survey record on this water
- Holds in
- 53–61 °F, stops feeding above 68 °F
- Typical

- October and November, on gravel in groundwater-fed shallows, often at the mouths of seeps rather than in the main current.
Native, and the driftless spring creeks and the northern forest headwaters hold it in different country: karst springs in the south, tannic sand and gravel in the north.
Is the water cold enough
No USGS gauge on this river reports water temperature, so there is no measured July mean to put beside the species' band. WDNR publishes no temperature classification for this water; the Cool band above is inferred from its management tier for the fishery, and it is not a thermometer.
What you may keep
Wisconsin DNR classifies this water as Class I, Class III. The management tier on those reaches is stocked, wild. This is a designation of the fishery and not the season and creel rules.
