Purpose

The Lake Tomah Priority Watershed Project plan assesses the nonpoint sources of pollution in the Lake Tomah Watershed and guides the implementation of nonpoint source control measures. These control measures are needed to meet specific water resource objectives for Lake Tomah and its tributaries. The purpose of this project is to reduce the amount of pollutants originating from nonpoint sources that reach surface water and groundwater within the Lake Tomah Priority Watershed Project area.

Objective

The primary objective of the project is to reduce nonpoint source pollution to the surface water and groundwater, and to enhance and protect the water quality of streams in the Lake Tomah Watershed. The amount of pollutants generated from the following five nonpoint sources were inventoried and analyzed in the Lake Tomah Watershed: eroding uplands (sediment and nutrients), eroding and trampled streambanks (sediment and habitat impairment), eroding gullies (sediment and nutrients), animal lots (oxygen demand and nutrients), and winter spread manure (oxygen demand and nutrients).

Outcome

The management strategies developed to achieve the water resource objectives are based on voluntary participants in the program controlling all nonpoint sources on their property identified as critical. Implementation of BMPs in the watershed would have a number of positive effects on the watershed streams. Stabilizing stream banks would increase available cover for adult fish and reduce sedimentation of riffles and pools. Increased cover and overall habitat improvement would improve carryover and survival of adult fish. Control of sedimentation and bank erosion would result in narrower and deeper streams, providing cooler temperatures and improved cover for adult fish.
