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.
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 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.
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.
