Water quality studies help the District identify potential actions and projects which can help improve the water quality of a lake. Once a water quality study is completed, a feasibility study is done. The feasibility and preliminary engineering study further evaluate the feasibility of
the recommended management activities.
The draft Arrowhead and Indianhead Lakes Feasibility/Preliminary Engineering Study was completed in October 2023.
The Arrowhead and Indianhead water quality study was completed in early 2022.
In addition to the water quality studies, the City of Edina also had fisheries surveys done on Arrowhead and Indianhead Lakes.
Pursuant to Minnesota Statute 103B.251, the Nine Mile Creek Watershed District will hold a public hearing on November 2, 2023 at 5:30 p.m., at the Nine Mile Creek Watershed District office, 12800 Gerard Drive, Eden Prairie, MN, to receive comments on proposed Arrowhead and Indianhead Lakes Water Quality Projects (Projects) and consider ordering the Projects. The cost of the Projects –two alum and iron in-lake treatments two years apart on Arrowhead Lake, one alum and iron in-lake treatment on Indianhead Lake, and the installation of in-lake aeration systems on both lakes – is estimated at approximately $600,000. The Projects will be funded through a watershed-wide levy on property within the watershed. For more information contact Randy Anhorn at 952-835-2078.

Lake User Survey
Thank you to everyone who took the lake user survey. The survey provided community feedback to Nine Mile Creek Watershed District staff, engineers, and the board of managers, along with the City of Edina. The feedback helped assist in the evaluation of management strategies designed to improve the health of Arrowhead Lake and Indianhead Lake. The survey targeted lakeshore owners and was active July 9 – August 16, 2021. 31 responses were received.
