The overall population is not known to be declining currently. Barriers that exclude Sea Lamprey protect this species from exposure to lampricides in upper reaches of many tributaries, and it is still relatively abundant in untreated streams. In the Great Lakes basin, most of its Canadian range, about half of the streams it is known to inhabit are subjected to ongoing chemical treatment for Sea Lamprey control, which causes significant mortality to larval lampreys. This small, nonparasitic lamprey is found in streams throughout the Laurentian Great Lakes basin and in southwestern Quebec.

An upgrade to the hydro-electric substation.Sewer system replacement project moves forward.Lake levels will vary during the drawdown between 5 feet below full-pond and 12 feet below full-pond, depending on the work requirements of contractors.Ī list of projects to be completed during the lake drawdown is listed below: The rate of refilling the lake is dependent upon weather conditions but information will be posted here regarding weekly lake levels.
It is anticipated that the lake will begin refilling on 3/31/23. The lake will begin to be lowered on 1/1/23 to support several important infrastructure projects. The town will work as strategically and efficiently as possible during the lake drawdown periods.
