The dam stands at a height of 6 feet and has a length of 60 feet, creating a reservoir with a storage capacity of 5,860 acre-feet and a surface area of 273 acres. The dam regulates Bigelow Brook, with a drainage area of 4.68 square miles, and can discharge up to 200 cubic feet per second through a spillway that is 25 feet wide.
Despite being assessed as in fair condition during its last inspection in May 2015, Mashapaug Pond Dam #1 South has been classified as having a significant hazard potential. The dam is subject to regular state regulation, inspection, and enforcement by the Connecticut Department of Energy and Environmental Protection (DEEP). While the dam has not been modified in recent years, its Emergency Action Plan (EAP) was last revised in December 1995, raising questions about its current readiness for emergencies. With a history dating back over a century, this dam plays a crucial role in providing recreational opportunities while also posing potential risks that must be carefully managed and monitored.
