Wachusett Reservoir, the second largest body of water in Massachusetts at 4,135 acres, is not open for paddling or any boating. The reservoir serves as a drinking water supply for the Boston metro area, containing 65 billion gallons of water. Due to its protected status, no boats, including kayaks and canoes, are allowed on the reservoir.

While paddling is prohibited, the reservoir offers other recreational opportunities along its 37 miles of shoreline. Fishing is permitted from designated shore areas during the season running from the first Saturday in April through November, ice conditions permitting. Popular fishing spots include Thomas Basin, Scar Hill Bluffs, and various gated access points. The reservoir is known for its diverse fish population, including smallmouth bass, lake trout, Atlantic salmon, and both rainbow and brown trout.

The area surrounding Wachusett Reservoir provides hiking and biking trails. Visitors can enjoy scenic views of the water and potentially spot wildlife like deer. The reservoir is open daily from sunrise to sunset, with several parking areas near access gates.

It's important to note that dogs are not allowed in the area around the reservoir. Additionally, all activities are restricted to designated areas to protect the water supply. While paddling enthusiasts cannot explore Wachusett Reservoir itself, the nearby Waushacum Ponds to the north near Sterling Junction do offer canoe and kayak access for those seeking a paddling experience in the region.
