This project will quantify and qualify the effectiveness of herbicide treatments and native plant re-establishment at Duck Lake through systematic vegetative surveys pre and post herbicide application and following mid-summer die-off of curly-leaf pondweed. The data and analysis will ultimately be used in the development of TMDLs, implementation and protection strategies for other lakes in the Middle Minnesota Major Watershed.
Varney Lake is owned and maintained by the City of white Bear Lake as part of its stormwater collection system. The City will excavate approximately 10,000 cubic yards of polycyclic aromatic hydrocarbons (PAH) contaminated sediment from Varney Lake (which is located in a residential portion of the City) and manage the sediments on site by encapsulating the sediment in a berm covered with clean top soil. The encapsulated sediment will be managed as a solid waste in what the MPCA refers to as a limited use solid waste landfill (Facility).
This project will provide the MPCA and all local partners in the Twin Cities Metropolitan Area (TCMA) the information and tools necessary to improve and/or maintain water quality with respect to chloride for the 7-county metropolitan area during the winter maintenace period.
