Is the Fryes Feeder good for brook trout?

Yes, on the classification rather than on a thermometer. WDNR has stocked brook trout into the Fryes Feeder across 5 recorded plants, between 2015 and 2018, and WDNR classes most of its typed water as cold — 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.

What the state's records say

Species: Brook trout (Salvelinus fontinalis)
In Wisconsin: native
Record here: stocked — no survey record on this water
Holds in: 53–61 °F, stops feeding above 68 °F
Typical: 6–11 inches
Spawns: 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's classification of the typed reaches is Cold, and that is a classification rather than a thermometer.

Gauge	Now	July mean
BADGER MILL CREEK AT VERONA, WI	56.7 °F	66.8 °F

What you may keep

Wisconsin DNR classifies this water as Class I. The management tier on those reaches is wild. This is a designation of the fishery and not the season and creel rules.
