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 complete an implementation plan, as required by the Minnesota Pollution Control Agency, for the Zumbro River turbidity TMDL project. It will also revise the Zumbro River Watershed Management Plan (completed 2007) to ensure it continues to reflect local needs, incorporates new information, and develops more effective linkages with related local, state and federal government programs.
The goal of this project is to finalize the Lake Pepin Watershed phosphorus total maximum daily load (TMDL) report by using the existing information and documentation prepared under previous contracts to prepare one TMDL report that addresses the impairments on the mainstem of the Mississippi River. Information developed to date for draft TMDLs on the Minnesota River mainstem will be documented for later use by the Minnesota Pollution Control Agency.
The goal of this project is to simulate up to ten scenarios using the recently completed Hydrologic Simulation Program FORTRAN (HSPF) model for the Mississippi River–Lake Pepin (MRLP) watershed. The mode will be used to investigate a variety of management scenarios to support further planning work and implementation in the watershed. Model scenarios are being developed to inform 1W1P planning activities and future implementation.
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.
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.
In previous phases of work, a Hydrologic Simulation Program FORTRAN (HSPF) model of the Zumbro River Watershed was developed to simulate hydrology and water quality for the 1995-2009 simulation period (Phase I), applied to evaluate various management scenarios for reducing sediment and nutrient loading (Phase II), and used to develop Total Maximum Daily Loads (TMDLs) for impaired stream segments and inform development of a nutrient TMDL for Rice Lake (Phase III).
The Olmsted County Soil and Water Conservation District will assist the Minnesota Pollution Control Agency (MPCA) with water quality monitoring and pollutant load calculations at four sub-watershed sites in the Zumbro River Watershed. Approximately 25 grab samples per site between ice-out and October 31 of 2019 will be collected along with field measurements and observations. Samples will be collected using procedures described in the Watershed Pollutant Load Monitoring Network (WPLMN) Standard Operating Procedures and Guidance (SOPG).
