Hillsboro Lake TWA 2015

Purpose

Western District proposes to conduct 319 Project Evaluation monitoring in the Hillsboro Lake Watershed located in eastern Vernon County, Wisconsin. The thirty-five square mile Hillsboro Lake Watershed was designated a priority watershed under the Wisconsin Nonpoint Source Pollution Abatement Program in 1993. A Hillsboro Priority Watershed Surface Water Resource Appraisal was completed in December of 1994 as a part of this project. The 1994 watershed appraisal included fish and habitat surveys at 11 sites, temperature monitoring at two sites and macroinvertebrate sampling at six sites.

Objective

The Western District will work with Watershed and County staff to determine the location, number and type of best management practices (BMPs) that were installed in the watershed since 1994. This will prioritize where the follow-up monitoring will be completed. Follow-up monitoring will target areas containing the greatest number and largest scale of BMPs installed. Individual streams or reaches of streams may also be targeted by this follow-up monitoring. Ideally, the sites will spread out enough to evaluate the two entire HUC 12 watersheds.

In 2015, WAV volunteers collected water samples as part of a 319 Project Evaluation monitoring in the Hillsboro Lake Watershed located in eastern Vernon County, Wisconsin. The thirty-five square mile Hillsboro Lake Watershed was designated a priority watershed under the Wisconsin Nonpoint Source Pollution Abatement Program in 1993 and a Hillsboro Priority Watershed Surface Water Resource Appraisal was completed in December of 1994. Follow-up monitoring in 2015 will target areas containing the greatest number and largest scale of best management practices (BMPs) installed.

Activities & Recommendations
Monitor Targeted Area
The West Branch of Baraboo River phosphorus monitoring site located at STH-33, should not be used as a stream site for calculation of phosphorus values, due to the site being located within Hillsboro Lake. Instead use the phosphorus values from the Sebranek Road site.
Review, Update Use Designation
The West Branch of Baraboo River fish natural community designations of cool-cold were verified, and the fish and aquatic life should be changed to good or supporting.
Delist Impaired Water
The West Branch should be removed from the impaired waters list for Low DO, phosphorus, sediment, total suspended solids and BOD. Biological information rated from fair to excellent and does not support listing the stream for biological impairment.
Delist Impaired Water
The West Branch of Baraboo River at Sebranek Road had a median value for phosphorus of 0.077 mg/l, but did not exceed the lower confidence limit for the 12 samples, thus is not considered as impaired for phosphorus. This water should not be listed as impaired.
