This project will reduce phosphorus loading from the watershed tributary to Silver Lake. The project includes a combination of structural water quality improvements in the SLV-10 subwatershed north of the lake, retrofits (including iron enhanced sand filtration) to the Silver Lake bioretention basin, small scale best management practices (BMPs) throughout the watershed, and educational signage in Joy Park. The elements of this project will reduce phosphorus loading to Silver Lake by a combined 15 pounds per year or 40% of the current watershed load.
The Greater Blue Earth River Basin is a large area within the Watonwan, Le Sueur, and Blue Earth River watersheds. Recent research by University of Minnesota, the National Center for Earth Dynamics, and others has found this basin to be the largest contributor of sediment to Lake Pepin.
This contract is a component of larger project (Snake River E.coli Microbial Source Tracking Study – Cycle II) in the Snake River Watershed located in the St. Croix river basin. The study will address microbial water quality impairments in the watershed. This study will conduct fecal bacteria source tracking using genetic markers across impaired streams in the watershed during the spring and summer months of 2021.
This project will complete a Total Maximum Daily Load (TMDL) study for the impaired reaches of the Snake River Basin. The project includes development of a Generalized Watershed Loading Function (GWLF) model for nutrient sources and Total Suspended Sediment (TSS), a spreadsheet version of a BATHTUB model of lake response for four lakes, and a bacteria source assessment. Wenck will also provide all stream channel data as a spreadsheet and locational database.
This project primarily focuses on riparian restoration (permanent vegetative buffer enhancements and plantings) on 6.5 miles (both sides) of targeted tributaries, ditches, and wetlands within five sub - watershed areas identified in the Snake River Watershed Restoration and Protection Strategy (WRAPS) Report. These plantings will consist of native perennials, trees, and shrubs where practical. In addition to the riparian plantings, this project will include fence exclusions for cattle and heavy use protections at cattle crossings in streams and ditches.
This phase of the project will complete a TMDL for the impaired reaches of the Snake River Basin. The project includes development of a Unit Area Load model for nutrient sources, a spreadsheet version of a BATHTUB lake response for four lakes, and a bacteria source assessment. Contractor will also provide all stream channel data as a spreadsheet database and in GIS.
The purpose of this project is to provide a new shared position in southeast Minnesota which will accelerate the adoption of soil health practices by leveraging the existing efforts of the National Resources Conservation Service and other organizations.
