Abstract:

Todd Lake Dam is a concrete capped, gravity rock wall and earth fill structure with a maximum height above the downstream channel of 16.5 feet. The 57 foot long concrete cap serves as a spillway and includes two 12 foot long depressed sections which permit the installation of 12 inch high flashboards. The dams size is intermediate with a significant hazard potential. The dam is in fair condition. Deficiencies in the areas of spillway capacity and possible structural stability require additional engineering investigations. Only a few relatively minor operation and maintenance improvements are necessary. Keywords include Visual inspection, Dam safety, Merrimack River Basin, Bradford New Hampshire, and Ring Brook.
