This project will layer hydrologic, hydraulic, geomorphic, and pollutant loading analysis with existing countywide PTMApp outputs to identify the four highest priority areas for BMP implementation in an eastern Nicollet County ravine system experiencing dramatic mass wasting events. Three alternatives for each priority site will be presented, including an evaluation of water quality benefit, construction costs, and a cost-benefit summary.
The Greater Blue Earth River Basin Alliance (GBERBA) along with Soil and Water Conservation Districts, Counties, landowners, and drainage authorities in the ten member counties will install conservation drainage practices to improve water quality. 103E drainage systems with documented sediment or water quality issues are the focus with the goal of installing 52 practices such as improved side inlets (grade stabilization structures), alternative tile inlets, denitrifying bioreactors, saturated buffers, storage wetlands and others.
The purpose of this project is to develop a detailed tool that can be used in all watersheds within the Otter Tail and Becker counties to prioritize, target, and measure implementation practices at the field scale. The PTM App will significantly increase the targeting capabilities in Otter Tail and Becker Counties. The Watershed Restoration and Protection Strategy has not been completed for Otter Tail County, yet, and the PTM App will be able to assist targeting and prioritizing when those documents are created.
Realizing the need for increased technical capacity in the field offices, the Becker, East Otter Tail and West Otter Tail Soil and Water Conservation Districts have developed an agreement that will increase technical capacity while minimizing costs to each district. The first step was taken in this agreement through the recent hire of a shared engineer. Currently, minimal survey grade equipment is owned by the districts. This grant will be used to purchase an integrated survey system.
