As part of federal re-licensure of the hydroelectric dam in town, surveys will be conducted by environmental engineers beginning this week.
The work will consist of walking the short river reach below each dam and inspecting the downstream side of each dam, basically looking for eel activity. Handheld flashlights will be used to help traverse the river reaches as well as spot eels in the water and on the dam face. Surveys are expected to continue one night per week through the end of June.
Costs associated with the survey, and other re-licensure activities, are being paid by the operator of the hydroelectric dam, not the Town of Rollinsford.
