The 4,135-acre reservoir was built between 1897-1908 by damming the South Branch of the Nashua river. Water was sent via an aqueduct to the Weston reservoir. It now receives some of its water from Quabbin Reservoir and still supplies the Boston area.

Things to know before you go
The primary purpose of DCR water and surrounding lands is drinking water supply. Public access, therefore, is carefully regulated and controlled to protect over 2 million people’s source of drinking water. State regulations require all entry and exit through gates or other designated areas only. Anything that could pollute the water supply system, such as litter or refuse of any sort, is prohibited. Please observe restrictions on recreational activities. Direct water contact activities, such as swimming and wading, are strictly prohibited by regulation. Dogs are not allowed on any DCR property associated with Wachusett Reservoir.
