DNR updates list of waters infested with aquatic invasives

The Minnesota Department of Natural Resources (DNR) has updated its website to show the additional lakes and river sections that were newly designated as waters infested with invasive species.

"The designation of waters with aquatic invasive species highlights the urgency for increased awareness and vigilance by people who are transporting water or water-related equipment such as boats, docks and boat lifts," said Jay Rendall, DNR invasive species prevention coordinator. "Extra effort is needed to clean, drain and dry all equipment to prevent further spread from infested waters."

Another major concern is the discovery in southwestern Minnesota waters of Asian carp, which have moved up from the Missouri River. That has led to the designation of many water bodies in that area as infested with bighead and silver carp.

The designations and associated regulations, such as prohibiting the harvest of bait and transport of water from those waters, are intended to help contain the aquatic invasive species present in the designated waters. The harvest of bait from designated infested waters with invasive fish such as bighead and silver carp is prohibited for commercial and non-commercial use.

St. Croix Valley lakes and bodies of water that have been added to the infested waters list are: Bighead and silver carp: The Mississippi River downstream of Lock and Dam 2 (Dakota, Goodhue, Hennepin, Houston, Wabasha, Washington and Winona counties); and the St. Croix River downstream of the Taylors Falls dam (Chisago and Washington counties).
