Bass Lake, located south of Bass Lake Road (Co. Rd. 10) and east of Northwest Blvd. (Co. Rd. 61), is a highly valued water resource providing both recreation and aesthetic benefits to City residents. Bass Lake is listed as an impaired water by the State of Minnesota and has an approved Total Maximum Daily Load (TMDL) for phosphorus. The TMDL report indicates a 480 pound reduction in phosphorus loading to Bass Lake is necessary to meet water quality goals and the City of Plymouth is required to make progress toward meeting the water quality goals in the TMDL.
A feasibility study was completed to provide a conceptual analysis of projects which would assist in making progress toward the water quality goal for Bass Lake. Thirty-nine sites were analyzed for potential improvements, which was reduced to several viable alternatives including a combination of smaller water quality ponds and alum treatment. A larger regional water quality pond was preferred; however, a site for a large regional pond could not be identified without the displacement of occupied properties.
While an alum treatment facility was originally planned, the City and Shingle Creek Watershed, in cooperation with the Bass Lake Improvement Association (BLIA) and area residents, will discuss the possibility of an in-lake treatment of alum which may be more effective. Coordination will occur during the spring and summer of 2018.
