Black Earth Creek Fishing Guides

About the Black Earth Creek

Black Earth Creek runs west through a narrow Driftless valley from Cross Plains, past Black Earth and Mazomanie, toward the Wisconsin River. It is one of the most written about trout streams in the Midwest and one of the very few nationally recognized wild trout fisheries that sits within a short drive of a major city. Madison is roughly half an hour east, which shapes both the pressure the creek receives and the amount of attention its management gets.

It is a genuine limestone spring creek. The valley sits in the Driftless Area, the corner of the upper Midwest the last glaciation missed, and the creek is fed by groundwater emerging from dolomite and sandstone rather than by surface runoff off a till plain. That gives it stable cold flows through the summer, water that stays open through a Wisconsin winter, and the dissolved minerals that support the heavy scud, sowbug and mayfly populations behind the fast trout growth here.

Brown trout are the fish and the population is wild and self sustaining through most of the creek. The fish run larger than the small stream average, and the lower reaches in particular hold browns that surprise people who expect a creek this size to produce only modest trout. Brook trout occupy the coldest spring fed headwater tributaries, and rainbows appear in some of the more heavily used public water. Decades of habitat work have shaped the stream substantially.

Access is the reason it is fishable at all given its reputation. Wisconsin holds extensive public fishing easements along the valley, marked and legally walkable, and there are state wildlife and fishery areas on the corridor as well. The easement system means anglers can fish long stretches without asking permission, which is unusual for private valley farmland and is the single biggest practical difference between this creek and much of the Driftless.

The fishing is technical and the creek fishes smaller than its reputation suggests. Clear spring water, wary wild browns and open grassy banks mean the fish usually see the angler first. Staying low, approaching from downstream and using fine tippet matter more than fly choice. Scuds and sowbugs work all year, caddis and small mayflies carry the spring and early summer, and terrestrials fished tight to the grass edge are as reliable as anything from midsummer on.

Access

Cross Plains - the village at the upper end of the trout water.
Black Earth Creek Wildlife Area - the state tract on the lower valley.
Wisconsin public fishing easements - the marked walkable easements along the valley.
Mazomanie - the village near the lower creek toward the Wisconsin River.
Madison - the nearest city, roughly half an hour east, with full services.
Wisconsin River - the larger river receiving the creek below Mazomanie.

Seasons

Spring: rising water and the first strong hatches, with the creek off color after heavy rain.
Summer: stable cold spring flows, heavy terrestrial fishing and the most technical conditions.
Fall: cooling water and brown trout coloring for the spawn in quiet valley stretches.
Winter: open water at the springs and a genuine catch and release winter season.
