Zebra mussel larvaeconfirmed in Leech Lake
The MinnesotaDepartment of Natural Resources has confirmed zebra mussels in their larvalstage in two locations in Leech Lake in Cass County. The DNR has found no adultzebra mussels in the lake, but the locations and numbers of zebra mussellarvae, called veligers (VEL-uh-jers), indicate a reproducing population may bepresent.
The DNR confirmedmore than 30 veligers from a sample collected in deep water off the shore ofPortage Bay, on the northeast side of the 110,000-acre lake, and more than 40veligers from a sample collected in the center of Kabekona Bay, on Leech Lake’swestern edge. No veligers were present in samples collected from three other sitesbetween Portage and Kabekona bays. The two sites where veligers were confirmedare nearly 17 miles apart.
The DNR Fisheriessection collected the samples as part of their Lake Survey Program, whichproactively gathers and analyzes samples from the 11 largest lakes in Minnesotaevery year. Leech Lake is the third-largest lake in the state.
Portage Bay is withinthe Leech Lake Reservation; Kabekona Bay is not. The DNR will work with theLeech Lake Band of Ojibwe, the Leech Lake Association, property owners andlocal governments to conduct a broader search and discuss options.
