This project goal is to conduct water chemistry monitoring at seventeen stream locations, to record and submit all data collected through this process, and to provide the information necessary for the calculation of water quality pollutant loads using the FLUX32 program.
The AgBMP Loan Program provides needed funding for local implementation of clean water practices at an extremely low cost, is unique in its structure and is not duplicated by any other source of funding.The AgBMP loan program provides 3% loans through local lenders to farmers, rural landowners, and agriculture supply businesses.
Currently, over 235 miles of open ditch are under the jurisdiction of the Brown County Ditch Authority. A majority of Brown County public ditches drain into large, impaired rivers including the Minnesota River (Turbidity), Cottonwood River (Turbidity/Fecal Coliform), Little Cottonwood River (Turbidity/Fecal Coliform) and Watonwan River (Turbidity/Fecal Coliform). Thus far the Brown County Drainage Authority has been inventorying ditches as requested for repair by residents in the ditch system.
The Drinking Water Contaminants of Emerging Concern (CEC) program identifies environmental contaminants for which current health-based standards currently do not exist or need to be updated, investigate the potential for human exposure to these chemicals, and develop guidance values for drinking water. Contaminants evaluated by CEC staff include contaminants that have been released or detected in Minnesota waters (surface water and groundwater) or that have the potential to migrate to or be detected in Minnesota waters.
Provide education, outreach and civic engagement necessary for the development of structural and non-structural best management practices needed to improve water quality within the Greater Blue Earth River Basin. General Education will have a regional focus to landowners. Outreach effort will be focused on regional officials, staff and landowners. Civic engagement efforts will have a smaller watershed scale focus with efforts resulting in structural BMPs being placed on the land and non-structural BMPs being adopted. Implementation of structural best management practices on the land.
The purpose of this project is to develop a framework to implement best management practices (BMPs) on ditches in headwater areas utilizing a partnership between drainage staff and the Greater Blue Earth River Basin Alliance (GBERBA). By replacing failing side-inlets with an alternative design, we can make strides towards our water quality and water quantity goals. The alternative inlets serve to prevent sediment and phosphorus from washing downstream and the design can also alleviate peak flows by temporarily storing stormwater.
The Minnesota River Basin Hydrological Simulation Program FORTRAN (HSPF) models, which simulate flow and pollutant transport, need to be refined to be consistent with the most recent external sources of land use, hydrologic response, and surface flow attributions. The primary goal of this work is to refine the hydrologic calibration in the Minnesota River basin.
The Minnesota River Basin Hydrological Simulation Program FORTRAN (HSPF) models simulate sediment erosion and transport, however these models periodically need to be adjusted to be consistent with the most recent sources of information regarding sediment distribution and loading rates. The goal of this project is to refine the sediment source partitioning and simulation in the Minnesota River basin using all relevant available sources of information.
This monitoring work expands on previously established routine water quality and flow sampling to include extensive fish and aquatic invertebrate surveys. Subsequent steps include assessment of the monitoring data to determine impairments, identification of stressors that are causing impairments, development of Total Maximum Daily Load (TMDL) studies using identification of pollutant sources using computer modeling and other techniques, civic engagement, and public education as approaches in progress towards water quality goals.
Locating the sources of sediment, phosphorus, and bacteria is integral to reducing the effect they have on a water body. The completion of the West Fork Des Moines River (WFDMR) Targeting and Prioritizing Endeavor will result in a set of data that is the most cost-effective for the implementation of Best Management Practices (BMPs) for all identified priority resources. The results will be expressed as the maximum reduction of a water quality contaminant (e.g. sediment, phosphorus, bacteria) at a priority resource (e.g. an impaired stream) for a given level of investment.
