Yahara-Monona PWS Plan - Nine Key Element Plan

Purpose

The Yahara-Monona Priority Watershed Project plan assesses the nonpoint sources of pollution in the Yahara-Monona Watershed and guides the implementation of nonpoint source control measures. The quality of water resouces in the Yahara-Monona Watershed is degraded from rainfall and snowmelt washing pollutants off various urban and rural land surfaces. Because of this and concerns expressed by local units of government, the watershed has been targeted for detailed management planning, educational activities, and water quality practices that can be implemented with financial assistance available through the Wisconsin Priority Watershed Program. The purpose of this project is to reduce the amount of pollutants originating from nonpoint sources that reach surface water and groundwater within the Yahara-Monona 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 Yahara-Monona Watershed.

Outcome

Based on urban and rural land uses, computer models were used to determine critical pollution source areas, pollutant quantities and the effects of management practices on reducing pollutant discharges from water runoff. Small-scale drainage basins were delineated for the urban part of the watershed. Model results show that the isthmus area and the Starkweather Creek subwatershed have relatively high pollutant discharges. While these areas are of significant concern, management practices should be pursued for most of the urban land in the watershed in order to safeguard water quality. Rural model results also indicate that about 5,000 acres of cropland and 11 livestock operations should have additional management controls.
