Lowell Lake

About Lowell Lake

The primary purpose of Lowell Lake is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by State Of Vermont - Fpr (state). It impounds the West River-tr near Londonderry.

The dam stands 16 feet tall and stretches 225 feet across, creates a reservoir covering 100 acres, has a maximum storage capacity of 1,475 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1850, the structure is one of the older dams in the region, with over a century and a half of service.

This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. The most recent inspection on record was 07/05/2017. That was 8 years ago, which is on the longer end for a high-hazard structure.

Living Downstream

If you live or work downstream of this dam, consider taking these steps: learn your local evacuation routes, check whether your county emergency management office has a dam failure inundation map, and sign up for local emergency alerts. The Vermont dam safety program can provide more specific information about emergency planning for this structure.
