This monitoring effort will focus on collecting chemistry and field data information from six sample locations on Hay Creek, Wells Creek, Bullard Creek and Gilbert Creek in Goodhue County and Miller Creek in Wabasha County within the Mississippi River-Lake Pepin Watershed (MRLP). These streams are typically cold water streams which outlet directly to the Mississippi River or Lake Pepin. This monitoring effort is to assist with the 10-year watershed-monitoring schedule that the Minnesota Pollution Control Agency has placed on major watersheds across the State.
The consultant LimnoTech will support response to Total Maximum Daily Load (TMDL) comments the peer review process, United States Environmental Protection Agency and public notice. They will then revise the TMDL document as needed and attend internal and external project meetings.
The goal of this project is to extend existing Hydrologic Simulation Program FORTRAN (HSPF) models through 2017 for the following major watersheds: Redwood, Cottonwood, Watonwan, Blue Earth, Le Sueur, Pomme de Terre, Minnesota River-Headwaters, and Lac Qui Parle watersheds.
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 will collect water samples at seventeen monitoring locations ranging in size from 23,173 acres (7 Mile Creek) to over 9 million acres (Minnesota River at St. Peter) as a part of the Watershed Pollutant Load Monitoring Network (WPLMN). The Minnesota State University - Water Resources Center (WRC) has been directly involved with the program and is familiar with the streams and hydrology of the region. In addition to monitoring, the WRC will review, manage and submit the data in formats provided by the Minnesota Pollution Control Agency (MPCA).
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).
