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 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.
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.
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.
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.
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.
