Project between Minnesota Department of Natural Resources and United States Army Corp of Engineers at Knowlton Creek Watershed to address a large amount of sediment deposited into the St. Louis River Area of Concern (AOC).
This project will support the MPCA’s water quality monitoring and assessment program. Specifically, the MPCA is developing a refined use designation process known as tiered aquatic life uses (TALU) to account for situations in which stream habitat has been compromised through hydrological alteration (e.g. channelization and ditching). An accurate state-wide determination of altered stream segments based upon the current National Hydrography Dataset (NHD) linework will assist in the assignment of the correct beneficial use within this new TALU framework.
