Lower east branch Pecatonica River (SP03)

The Lower east branch Pecatonica River watershed, in the western part of Green County and northeastern Lafayette County, is a priority watershed project under the Wisconsin Nonpoint Source Water Pollution Abatement Program. A number of smaller trout streams in the watershed (Wisconsin DNR, 1980) are affected by polluted runoff.

A detailed description of water quality conditions in the watershed prior to the beginning of the priority watershed project can be found in Lower east branch Pecatonica Priority watershed project: Water resources appraisal report (Marshall, 1991). A detailed description of the watershed project goals and objectives can be found in the Nonpoint source control plan for the lower east branch Pecatonica River priority watershed project (Haynes, 1992).

Two permitted facilities discharge to surface water in the watershed, the villages of Argyle and Blanchardville. Information on these municipal point source dischargers can be found in the point source section of this document.
