The goal of the Pomme de Terre River Association (JPB) is to improve the local water resources within the watershed through targeted voluntary efforts and the building of strong relationships with local landowners, producers, and citizens. The Pomme de Terre River is currently not meeting state water quality for sediment. The purpose of this project is to strategically work towards a 53% sediment reduction goal at the mouth of the Pomme de Terre River based on a Watershed Restoration and Protection Strategy document.
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.
Pope County Ditch 6 (CD 6) is an 18 mile channelized watershed and a primary tributary to Ashley Creek. CD6 and Ashley Creek are impaired for bacteria, dissolved oxygen and aquatic organisms. This project will address the storm water runoff concerns identified within this public drainage system in conjunction with repairs scheduled for 2017-2018. Alternative intake structures to manage nutrients and other practices, such as water and sediment control basins, will be installed to retain water on the upland properties and minimize flow rate and velocity.
