Middle Pecatonica River watershed (SP08)

The Middle Pecatonica River watershed in central Lafayette County is dominated by agricultural land uses. Two municipal permittees discharge to surface water in the watershed: Belmont and Darlington. We know little about water quality or in-stream habitat of streams in this watershed.

The slender madtom, an endangered fish species in Wisconsin, has been found in four streams in the watershed: Bonner branch, Cottage Inn branch, Otter branch and Wood branch (Fago, 1982).
