Snake Pond is a natural kettle hole pond and is fed by groundwater reflecting the groundwater levels. During years with low groundwater levels, large portions of the pond shoreline areas are exposed. 

The pond's 1.6 miles of shoreline are moderately developed with houses on the northern and southeastern ends and a summer camp (Camp Good News) on the eastern shore. The town beach at the southern end of the pond is heavily used by swimmers during the summer months.
