The MPCA has identified 13 stream sites in the watershed to characterize watershed water quality. This project will supplement and complement the identification of the top 50 sites in the watershed that are contributing to water impairment and also help in identification of priority watersheds in the re-write of the watershed comprehensive plan. Water samples and field measurements will be collected at each monitoring location ranging from baseline events to high flow events.
This project will identify and compile existing nitrate data from groundwaters and surface waters in the Lower Mississippi Basin (LMB) generally and focus on the Root River Watershed. The purpose is to investigate the quantity and quality of existing nitrate data, and to organize it for use in comprehensive watershed strategy development (including assessment, TMDL computation and identification and study of nitrate sources and delivery mechanisms).
This project will construct, calibrate, and validate an HSPF watershed model for the Zumbro River watershed. The consultant will produce HSPF watershed models that can readily be used to provide information to support conventional parameter Total Maximum Daily Load (TMDLs). The consultant will clearly demonstrate that the models generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen that are consistent with available sets of observed data.
This project supports monitoring and assessment activities by MPCA EAO staff and includes lab analysis, equipment, and fieldwork expenses associated with monitoring and assessment activities within the described priority watersheds.
Lake Monitoring: Lakes are monitored for nutrients, clarity and other information to provide the data needed to assess the aquatic recreation use support.
The purpose of this effort is to create an educational video that will “bring to life” geo-scientific information related to groundwater movement in southeast Minnesota. This video will be used by the Minnesota Pollution Control Agency (MPCA), Minnesota Department of Agriculture (MDA) and other regional partners to help explain the local geology and related groundwater movement. It is anticipated that the video will be used at meetings and other events related to water resource management and natural resource issues. In addition, three stand alone high resolution graphics will be created.
The goal of this project is to investigate nitrate transport and the sources of nitrate in karst for more effective implementation of best management practices that will reduce nitrate concentrations in ground and surface water.
The Zumbro River Watershed is a major watershed in the Lower Mississippi River basin in SE Minnesota. It includes parts of six counties, covering 910,291 acres. This project will assess all 13 stream reaches in the Zumbro River Watershed to determine if they are meeting their designated uses. The monitoring will entail collecting water chemistry and field parameters.
The goal of this project is to test the sensitivity of the Zumbro River Watershed Hydrological Simulation Program FORTRAN (HSPF) model management scenario results. Additional goals are to develop Total Maximum Daily Loads (TMDLs) for impaired stream reaches and Rice Lake, which will be documented in a TMDL Report. The consultant will apply the existing calibrated and validated Zumbro River Watershed HSPF model to construct load duration curves to develop TMDLs.
