The data collected in this workplan is the foundation for an accurate TMDL allocation and accurate implementation strategy design. Current and historic phosphorus inputs will be calculated and evaluated as to source. Nutrient and algal history and trends in sedimentation will be reconstructed to identify ecological changes that have occurred in the lakes both recently and historically.
This project will complete a TMDL equation and report and an implementation plan for Deer Creek. The TMDL report will describe turbidity impacts to aquatic life uses of Deer Creek, correlate turbidity to other pollutants (sediment, suspended solids, etc.), describe and quantify unique turbidity/sediment stressors which include groundwater influences, legacy impacts of the watershed and stream channel, significant in-stream and near stream sources (slumps, bank erosion, etc.) and upland contributions.
Deer Creek has been identified as an impaired water body. This project will quantify the reductions in pollutant loading that would be necessary to bring water quality in the creek to an acceptable level. The project also includes collection of any additional data needed for stream channel modeling scenarios.
The goal of this project is to construct, calibrate, and validate three HSPF watershed models. The project will result in HSPF models that can readily be used to provide information to support conventional parameter TMDLs. The models are expected to generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data.
The goal of this project is to supplement and refine the Deer Creek Watershed TMDL Report and Implementation Plan project with detailed determinations of critical source areas and prioritization of the associated management practices, facilitated by additional meetings with local resource managers and validated with a field survey. Completed work will more fully inform the TMDL report and TMDL implementation plan on critical source areas of sediment and quantify those sources.
This project will define the major factors causing harm to fish and other river and stream life within the Nemadji watershed. Stressor identification is a formal and rigorous process to identify these factors, explain the linkages between the results of biological monitoring and water quality assessments, and organize this information into a structure of scientific evidence that supports the conclusions of the process. Stressor identification is a component of the Watershed Restoration and protection (WRAP) approach.
This project is to complete the Watershed Restoration and Protection (WRAP) process, complete Total Maximum Daily Load (TMDL) reports and calculations, develop and discuss Hydrological Simulation Program FORTRAN (HSPF) model scenarios, set restoration and protection priorities, and integrate all of this information in the final WRAPS report.
Approximately 70 percent of all Minnesotans rely on groundwater as their primary source of drinking water. Wells used for drinking water must be properly sealed when removed from service to protect both public health and Minnesota’s invaluable groundwater resources. The Minnesota Department of Health protects both public health and groundwater by assuring the proper sealing of unused wells.
Clean Water funds are being provided to well owners as a 50% cost-share assistance for sealing unused public water-supply wells.
