Nonquit Pond is one of nine reservoirs that supply the Newport Water drinking water supply system. Nonquit Pond is formed by the dam on Almy Brook on Pond Bridge Road.  

Nonquit Pond is also one of the watershed’s most important anadromous fish habitats, providing an important spawning area for river herring. Young herring hatch and begin their lives in freshwater ponds and streams and migrate to the Atlantic Ocean to live during the summer, fall and winter. The adult herring return each spring using the fishway at the dam to reach the fresh waters of their birth to spawn. Numbers of river herring have varied significantly over the years, and currently are at a very low count.
