Improving and Protecting Local Water Quality
South Creek Restoration
In 2018, a project restored a tributary of South Creek, a DNR-designated trout stream, separating it from a City stormwater pond. The project benefits included improved water quality, habitat enhancement and fisheries protection.
In 2019, the City restored a channelized 1,400 linear feet of the stream. In addition, the project converted six acres of previously cropped land to native vegetation to act as a stream buffer and provide pollinator habitat.
Lake Monitoring and Studies
The City conducts annual lake studies on Lake Marion, Lee Lake, Kingsley Lake, Orchard Lake, East Lake and Valley Lake. These studies help to develop innovative water quality enhancements, develop an ongoing database for long-term monitoring and helps to initiate rapid response for aquatic invasive species.
Prevention and Control of Aquatic Invasive Species
The City combats the spread of aquatic invasive species (AIS) through:
- Watercraft inspections at Lake Marion and Orchard Lake
- Treatment of curlyleaf pondweed and Eurasian watermilfoil
- Monthly targeted AIS searches
Rough Fish Management in East Lake
In 2018, the City of Lakeville estimated the biomass of common carp in East Lake. Carp abundance was found to be above 100 kg/ha, which is the threshold at which negative water quality impacts are observed. In addition, tracking devices were installed to determine if carp were able to freely travel outside of the lake.
