The Vermont Department of Fish and Wildlife is issuing an advisory not to use Winooski River water for several days after a chemical is used to kill sea lamprey.
Sea Lamprey can devastate the populations of game fish such as lake trout
The advisory goes into effect Tuesday at 7 a.m. for a stretch of river from the dam in the City of Winooski downstream into Lake Champlain.
The advisory includes parts of Lake Champlain four and a half miles north of the mouth of the river and three miles south.
The chemical to kill the young lamprey will dissipate over several days.
Recreational use restrictions are expected to last from three to six days. Household and agricultural restrictions may last from four to eight days.
