Echo Lake is in a municipal park, and the town maintains a swimming beach along the southeast shore.  A road runs along the eastern side of the 10.7-acre pond, but the western side is wooded.

The most abundant species during our September 2005 survey was the invasive Najas minor.  The plant occurred in a narrow band around the lake, limited to the shallowest areas.  Potamogeton bicupulatus, also was abundant, occurring in slightly deeper water than the Najas minor .  Elodea nuttallii, Potamogeton epihydrus and Callitriche sp. were found along the lake’s southeast shore, while scattered patches of Lemna minor were recorded at the northern end of the lake.
