This project will directly inform the Lake of the Woods (LoW )TMDL process by identifying nutrient reduction targets, a timeline of phosphorus loadings to the lake, and measures of historical in-lake variability (e.g., nutrients, biological communities). Results will complement and build on ongoing research efforts on internal loading and sediment core analysis.
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 support the collection and analysis of sediment core samples, from each of the five bays ( Little Traverse, Big Traverse, Muskeg, Sabaskong and 4-Mile Bays), to ensure adequate characterization of the P fluxes from deposited sediment and equilibrium P fluxes from re-suspended sediment.
This project will construct, calibrate, a set of HSPF watershed models covering the entire area of the Lake of the Woods drainage, including the Rainy River watershed. The consultant will produce HSPF models that can readily be used to provide information to support conventional parameter TMDLs. The consultant will clearly demonstrate that these models generate predicted output timeseries for hydrology which are consistent with available sets of observed data.
This project will construct, calibrate, and validate an HSPF watershed model for the Lake of the Woods River watershed. The consultants will produce HSPF watershed models that can readily be used to provide information to support conventional parameter TMDLs. The consultants will clearly demonstrate that the models generate predicted output time series for hydrology, sediment, nutrients, and dissolved oxygen that are consistent with available sets of observed data.
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.
This project will determine pre- and post-settlement nutrient trends from sediment chronology, fossil diatom assemblages, and from sediment profiles representing human history in the region (i.e., at least 150 years). Project activities include sample collection; sample preparation; diatom analysis; database creation and management; and data interpretation. Sample cores will be taken on the Lake of the Woods in five major bays (i.e., Four-mile, Muskeg, Sabaskong, Little Traverse, and Big Traverse) in the southern basin.
The purpose of this project is to gain an understanding of modern and historical nutrient and thermal dynamics in Lake of the Woods using modeling, monitoring, sediment core analysis, and whole basin techniques.
The Lake of the Woods (LOW) Total Maximum Daily Load (TMDL) study will: (1) identify water quality goals for the Minnesota portions of the LOW/Rainy River Watershed; (2) recommend nutrient allocations to achieve TMDLs where waters do not meet standards; and (3) provide opportunities for stakeholders to engage in the process of watershed-management planning to adopt protection and restoration strategies. The project will include existing in-lake and watershed model updates, TMDL component development, restoration plan development, and public participation.
This project will provide monitoring of four of the major watersheds (8-digit Hydrologic Unit Codes) in the western part of the Rainy River Basin. Staff from the Lake of the Woods SWCD will conduct water quality sampling, review, manage and provide collected data to the Minnesota Pollution Control Agency (MPCA).
This project will support the collection of water-quality samples and gauge streamflow near the mouths of the Rainy and Warroad Rivers; collect water-quality samples at 10 sites in LOW; and measure streamflow velocities and cross-sectional areas of 5 channel constrictions in LOW.
This project will gather watershed data necessary for the development of a Watershed Restoration and Protection Strategy to maintain or improve water quality within the LoW Watershed; and establish project and sub-basin work groups and/or focus groups to guide the MWRPP process.
This project is to conduct water chemistry monitoring at two subwatershed sites and two major watershed sites in 2016 and 2017 based on flow conditions, targeting runoff events using protocols defined in the Watershed Pollutant Load Monitoring Network (WPLMN) Standard Operating Procedures and Guidance. The data collected will be submitted to Minnesota Pollution Control Agency (MPCA) and used for calculating pollutant loads.
With a perceived increase in the frequency and intensity of cyanobacterial algal blooms in Lake of the Woods (LOW), there has been an increased effort to collect information about the nature of algal blooms, nutrient concentrations and sources of nutrients to the LOW.
This project will address Minnesota Pollution Control Agency (MPCA), United States Environment Protection Agency (EPA), and public comments on draft Total Maximum Daily Load (TMDL) studies and Watershed Restoration and Protection Strategy (WRAPS) reports, preliminary draft TMDL studies, and public noticed TMDL studies and WRAPS reports for the Lower Red River Watershed and the Lake of the Woods Watershed and produce final versions of the TMDL studies and WRAPS reports for each watershed.
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.
Regionally, nitrate nitrogen concentrations are continuing to increase in both surface water and ground water based on monitoring data. The increasing trends are thought to be attributable to over application of manure and commercial nutrients on row-cropped fields. In order for nitrate concentrations to decrease, nutrient management is needed throughout the basin. Two nutrient management specialists will assist landowners in the eleven-county Southeast Minnesota Area with writing nutrient management plans and implementing conservation practices for manure and fertilizer use.
The purpose of this contract is to establish an international watershed coordinator for the Rainy River- Lake of the Woods (RR-LOW) watershed. The coordinator will assist the Minnesota Pollution Control Agency (MPCA) in facilitating and enhancing civic engagement and public participation activities through collaboration and integration of the efforts of groups working on watershed activities at local, state/provincial, tribal, and bi-national levels.
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 lack of sewage treatment in some small communities in Southeast Minnesota is causing surface water and groundwater pollution. Fourteen of these communities will be the target of the technical assistance provided by this project. These communities have community or individual straight pipes discharging raw sewage directly into the environment;surfacing sewage or have sewage contaminating groundwater.
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 Lake of the Woods Watershed Assessment will include the waters of Warroad River and Willow Creek in Roseau County and Williams Creek and Bostic Creek in Lake of the Woods (LOW) County. This assessment project will focus on the collection of water chemistry and field parameters at the six key sites identified and modified by MPCA. One site on the Warroad River will have extra nutrient and chlorophyll analysis done. Sites are located in the lower reaches of each surface water system.
This project will support the operation and maintenance of a stream gage that records stage, index-velocity and water temperature at Wheeler's Point on the Rainy River. The USGS will visit the stream gage approximately every six (6) weeks to perform maintenance and, as needed, to define the range of flows that occur.
