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.
Co-sponsorship and assistance with a portion of the financial support for the 9th & 10th Annual International Lake of the Woods Water Quality Forum (Forum) to be held on March 7-8, 2012 and March 13-14, 2013 at the Rainy River Community College in International Falls, Minnesota. The Forum will feature the latest information on research conducted by Canadian and U.S. researchers regarding the International Lake of the Woods waters.
The goal of this project is to determine: 1) temperature and seasonal variations in sediment chemical-textural characteristics (upper 10-cm sediment layer) and rates of P release from sediments; and 2) vertical variations in mobile P concentrations in the sediment column of Big Traverse Bay in order to better understand the role of internal P loading to the P economy of LOW and for the development of the LOW TMDL.
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).
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 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.
