Fort Meadow Reservoir is a 260-acre lake between the town of Hudson and the city of Marlborough. The reservoir was created by damming a stream that flowed into a natural kettle pond. 

The pond consists of a primary and secondary basin, separated by a narrows near the center of the two. The primary basin is split into two sections by a causeway on Reservoir Street..

Two public beaches are located in the secondary basin. Centennial Beach lies on the Hudson side while Memorial Beach lies on the Marlborough side. The reservoir also has a conservation area called The Grove, with walking trails, picnic areas, and canoe access.

The AllTrails website has a description and map of a hike at The Grove Conservation Area.
