Public Meeting: Alimagnet Lake Feasibility Study
This spring and summer, the Vermillion River Watershed Joint Powers Organization (VRWJPO) is leading an Alimagnet Lake alum (aluminum sulfate) treatment feasibility study. City of Burnsville and City of Apple Valley natural resources staff are also participating in the process. VRWJPO has hired a consultant, Barr Engineering, to conduct field work, analyze data and help put together the final feasibility report. This report is expected to be completed in July. We are hosting a public meeting on July 20, 2023 where the findings of the report will be presented.
What is an alum treatment?
An alum treatment is a common water quality improvement practice in shallow lakes that have excessive phosphorus and poor water clarity as a result of algae growth. Often times phosphorus is released into the water column from lake bottom sediments during the summer months. When alum is added to the water, it attaches to phosphorus and falls to the bottom of the lake, preventing it from feeding algae and improving water clarity. Increased clarity following alum treatments can also lead to increased aquatic plant growth, which help to keep phosphorus levels in check.
One of the first steps in planning for a potential alum treatment is to conduct a feasibility study, which will determine whether Alimagnet Lake is a good candidate for the treatment, and if it is, how to most effectively apply alum in the lake, and the estimated costs. The study will also look at alternative solutions to improve water quality, other than an alum treatment.
At the public meeting, there will be a short presentation to present the findings of the study and then time for attendees to ask questions or provide feedback on the findings. If alum treatment is determined to be a feasible option for Alimagnet Lake, VRWJPO would anticipate applying for a grant in late summer of 2023 to obtain funding to complete the work. No treatment would occur prior to 2024.
If you have any questions regarding the public meeting, please feel free to contact Caleb at 952-895-4543 or caleb.ashling@burnsvillemn.gov.

Lawns Reimagined Pilot Program
Have you ever looked out at your lawn and thought, “sure would be nice to water less often, reduce the need to fertilize, and spend less time mowing”? Well, we’ve got the program for you! Our new program – Lawns Reimagined – assists landowners in installing a more resilient lawn to reduce water and fertilizer use, and cut down on mowing frequency during the growing season.
Lawns Reimagined is a new program provided through a partnership between the Dakota SWCD, Dakota County, and the Vermillion River Watershed Joint Powers Organization. The goal of the program is to create healthy looking lawns using deeper rooted grasses that are more resilient to weather conditions and climate change while maintaining traditional turfgrass lawn uses.
These lawns will be composed of fescue grass blends that require little to no watering or fertilizer post-establishment; reducing the impact lawns have on the groundwater supply and decreasing nutrient loss to waterbodies through runoff and lawn clippings. It is recommended to reduce mowing frequency which results in reduced carbon emissions from lawn mowers and healthier air at a local level.
The Dakota SWCD will be hosting two workshops for Dakota County residents:
* June 5 in Apple Valley (Municipal Center) at 6 p.m.
* June 12 in Rosemount (Steeple Center) at 6 p.m.
At the workshops, participants will learn about the benefits of an alternative lawn type, along with technical guidance on site preparation, seeding, and long-term maintenance. From there, landowners can apply to receive further assistance. Once applicants have been approved, SWCD staff complete a site visit to further guide site preparation, seeding, and answer any additional questions. Landowners then complete the site preparation and Dakota SWCD will provide landowners with the seed to complete a fall seeding. If the participants are willing to do a little work, the cost to them will be minimal to none!
