National Program for Inspection of Non-Federal Dams. Rogers Lake Dam (CT 00418), Connecticut River Basin, Old Lyme, Connecticut. Phase I Inspection Report
The dam at Rogers Lake is an earth embankment with vertical concrete wall approximately 129 feet in length including a spillway length of 29 feet. The maximum height of the dam is 7 feet. The spillway is an uncontrolled concrete broad crested weir and located about 38 feet from the right dam abutment. The outlet works consists of a gated drop inlet with a 36 inch diameter outlet conduit and is located at the right spillway abutment. Based on a visual inspection at the site, the dam is considered to be in FAIR condition. However, there are some areas of concern which must be corrected to assure the long term performance of this dam. Signs of concern include; seepage through the downstream concrete wall; large trees next to the downstream face; cracks and spalling of the upstream wall left of the spillway; probable seepage through the downstream face of the spillway; lack of erosion protection on the banks of the discharge channel near the dam; and unprotected low areas on the left and right sides of the dam. The maximum spillway capacity is equal to 344 CFS which represents only 13 percent of the test flood outflow, therefore, the spillway capacity is considered inadequate.
