About Wirth Lake

Wirth Lake is a 38-acre lake located adjacent to Bassett Creek in the City of Golden Valley within Theodore Wirth Regional Park (MPRB), which is owned and maintained by the Minneapolis Park and Recreation Board. The lake is an important recreational resource to the residents of north Minneapolis and surrounding inner-ring suburbs. A public beach and parkland surrounding the lake provide opportunities for swimming, fishing, picnicking, and aesthetic viewing, and non-motorized boating.

Wirth Lake has a maximum depth of 26 feet although much of the lake is shallow which supports emergent and submerged aquatic vegetation. The 405-acre watershed of Wirth Lake is almost fully developed (46% of which is developed as parkland) and the lake has four main inlets - three storm sewers and one open channel in the north.

In 2012, the BCWMC (in cooperation with the MPRB and the City of Golden Valley and with a grant from the Clean Water Legacy Fund) completed a project which modified the Wirth Lake outlet to prevent backflow from Bassett Creek into Wirth Lake during periods of high water in the creek. This project, along with other improvements in the watershed reduced total phosphorus levels in the lake considerably. The lake is slated to be removed from the Impaired Waters List when the 2014 state-wide list is approved by the EPA. The lake remains of the Impaired Waters List for high mercury and chloride levels.

The BCWMC does not typically monitor water quality on Wirth Lake but relies on the MPRB monitoring program.
