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 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 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.
The primary goal of this project is to examine the calibration and validation of recently extended Hydrological Simulation Program – FORTRAN (HSPF) watershed models for the Mississippi River-Headwaters, Mississippi River-Grand Rapids, Mississippi River-Brainerd, Mississippi River-Sartell, Mississippi River-St. Cloud, Leech Lake, Pine River, Crow Wing River, Long Prairie River, and Redeye River watersheds and revise the calibration.
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.
