The goal of this project is to construct, calibrate, and validate three HSPF watershed models. The project will result in HSPF models that can readily be used to provide information to support conventional parameter TMDLs. The models are expected to generate predicted output timeseries for hydrology, sediment, nutrients, and dissolved oxygen which are consistent with available sets of observed data.
Demand for Engineering services in Northeast Minnesota's nine-county Area III Technical Service Area is exceeding the capacity to deliver the needed services. There are increased requests from Soil and Water Conservation Districts for engineering needed to design and install Best Management Practices in part due to requests related to Clean Water Fund projects. These funds will be used to hire an engineer, which will increase engineering capacity and result in the completion of at least five additional projects per year.
This project will gather watershed data necessary for the development of a Watershed Restoration and Protection Strategy (WRAPS) report to maintain and improve water quality for the St Louis River Watershed.
The St. Louis River watershed is one of the largest watersheds in northern Minnesota and the largest single contributing watershed to Lake Superior. Surface waters are abundant with 353 lakes and 97 streams segments. Large areas of forest and wetlands help to sustain areas of exceptional water quality. However, land use changes have degraded many lakes, rivers, and streams. 21 stream reaches have aquatic life impairments, as identified by high turbidity (1 reach), poor quality aquatic macro-invertebrate community (16 reaches), and/or poor quality fish community (12 reaches).
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 Aitkin County Soil and Water Conservation District will partner with local lake associations and other eligible community partners to reduce the impacts of storm water runoff and retain water on the land. We will implement a mini-grant program that will install rain gardens and native vegetation buffers along shorelines using deep-rooted native vegetation that will filter runoff, promote infiltration, and control stormwater runoff and soil erosion.
The objective of this sampling plan is to quantify the inputs and outputs of methyl-mercury in the St. Louis River. Mercury can be bound to organic carbon or suspended solids; therefore, it is necessary to determine loadings of them as well. To get loadings, this sampling plan includes event and base flow monitoring at key tributaries to the St. Louis River and at stations within the St. Louis River.
The goal of this project is the continued development of an overall strategy for reduction of turbidity/TSS, with sets of sediment reduction initiatives and actions for various sources, to address the Minnesota River Turbidity TMDL and the South Metro Mississippi River TSS TMDL. The overall strategy will be used to help establish a path towards achieving the required reductions of turbidity/TSS.
This project will provide complementary (same year) physical and chemical data sets for three MPCA prioritized lakes in NE Minnesota to incorporate into the overall State database for MPCA assessment purposes as well as research purposes.
