The Vermont Department of Fish and Wildlife is lifting restrictions on using the waters of the Winooski River and Lake Champlain after treating the river with chemicals to kill sea lamprey.
The advisory will be lifted at 1 p.m. today.
The advisory was implemented earlier this week in preparation for treating the Winooski River with the lampricide TFM near the dam between Winooski and Burlington.
The advisory extended into Lake Champlain north and south of where the river empties into the lake.
State officials say all traces of TFM have now dissipated and the water is safe to use.
Lamprey are a parasitic fish that prey on game fish such as trout and salmon.
