Thank you to everyone who supported the fight to save the riverbank at Grupes Reservoir. The Dept of Energy and Environmental Protection has issued a decision to grant the First Taxing District the permit it has requested which will allow for increasing the height of the dam, removing all vegetation and building a series of walls and berms along the east bank for 1500 feet from the dam along the service road. The area will include walls that extend in front of the Browne Wildlife Sanctuary and will disconnect its wetlands from the reservoir unfortunately. We have appealed the decision and will update this page if the decision is reversed.
Thank you to everyone who supported us financially and joined the Online Public Hearing on September 29th. There were over 70 participants. se.
More detailed information: Plans to repair and raise the Grupes Reservoir Dam in New Canaan include removing over 400 native trees and shrubs along 1500 feet of riverbank in order to build a series of walls and berms along the eastern riverbank. The First Taxing District of Norwalk water company provides drinking water to Norwalk and a small section of New Canaan from the 4 dams and reservoirs it operates along the Silvermine River. The dams begin at the river’s source in Lewisboro, NY and end at the Grupes Dam along Valley Road, just adjacent to the New Canaan Land Trust’s Browne Wildlife Sanctuary.
NRWA and the New Canaan Land Trust are concerned that the negative environmental effects of removing the vegetation from the riverbank and disconnecting the wetlands of Browne Sanctuary from the Silvermine River have not been included for review in the proposed permit application for the work that was submitted to the Dept of Energy and Environmental Protection (DEEP). The dam, built in 1871, is in need of repair. NRWA appreciates the importance of the dam safety issues involved, but argues that a full review of the effects of the plan to wall off the eastern bank of the river should have been required. There are feasible alternative plans that repair the dam, protect the homes below the dam from potential flooding, and spare the riverbank and the beautiful, pristine wetlands that have been protected by the Land Trust since the 1960s.
