Aquatic invasive species such as Carp, zebra mussels, and Eurasian watermilfoil now inhabit many lakes and rivers in Minnesota, including some of our local lakes. These species create problems for native aquatic animals and plants and for people who enjoy using our lakes for recreation.
Invasive Aquatic Animals
The DNR discovered zebra mussels in Prior Lake in 2009. Zebra mussels pose serious ecological and economic threats to Minnesota Lakes. Heavy infestations can kill native mussels, may impact fish populations, can interfere with recreation, and can increase costs for industry, including power and water supply facilities. Visit The DNR's aquatic invasive species web page to learn what you can do to prevent further infestation.
Common Carp are present in many of our lakes, including Spring Lake, Prior Lake, Jeffers Pond, and Pike Lake. Carp are one of the most damaging aquatic invasive species due to the severe impacts they have on lakes and wetlands. Their feeding habits disrupt aquatic plants, stir up bottom sediments (making the water muddy), and cause an overall decline in water quality by releasing phosphorus that feeds algae blooms.
The Prior Lake-Spring Lake Watershed District (PLSLWD)is a local government agency involved with Carp Management. The PLSLWD is actively working to target and remove carp from our lakes through their integrated Pest Management Plan for Common Carp.
Invasive Aquatic Plants
Eurasian Watermilfoil is present in Prior Lake, Pike Lake, and Jeffers Pond. Curly-leaf Pondweed has also been found in local lakes including Prior Lake and Spring Lake. Both of these invasive plants were accidentally introduced into our lakes.
