Project Detail

Seymour Creek and Upper Baraboo River (LW24) Watershed Planning

Purpose

The Seymour Creek and Upper Baraboo River Watershed, located in Juneau, Monroe, Sauk and Vernon Counties, contains all of the streams that drain to the uppermost 30 miles of the Baraboo River which eventually reaches the Wisconsin River 120 miles downstream near Portage. in 2017, the Hillsboro Lake Targeted Watershed Assessment was written up as the Hillsboro Water Quality Plan. The plan for LW24, therefore focuses on the southwestern part of the larger watershed. The land in this watershed is characteristic of the driftless area with steep hills, however many stream valleys are fairly wide. Agricultural activities are found both on the wider ridgetops and in most valleys.

The Hillsboro Lake targeted watershed contains two major streams, West Branch of the Baraboo River (WBIC: 1288400), and South Branch Creek (WBIC: 1289800). The South Branch Creek subwatershed is approximately 11,428 acres in size, and land use in the subwatershed is dominantly agriculture (48%), followed by forest (31%), grassland/pasture (16%), residential (5%), and water (0.12%) . The major tributary of South Branch Creek is Beaver Creek (WBIC: 1290100). Both the West Branch and South Branch flow into Hillsboro Lake at the west end. West Branch Creek subwatershed is approximately 11,635 acres, and land use in the subwatershed is primarily agricultural (43%), followed by forest (36%), grassland/pasture (16%), residential (5%), and water (0.02%). The major tributary of The West Branch is an unnamed tributary (WBIC: 1290900), also known locally as Dilly Creek.

Objective

This Water Quality Management Plan was created under the state’s Water Quality Management Planning and Water Resources Monitoring Programs. The plan reflects Water Quality Bureau and Water Resources Monitoring Strategy 2015-2020 goals and priorities and fulfills Areawide Water Quality Management Planning milestones under the Clean Water Act, Section 208. Condition information and resource management recommendations support and guide program priorities for the plan area.
