The Quabbin Aqueduct carries water from the Quabbin Reservoir to the Wachusett Reservoir. It is part of the Eastern Massachusetts public water supply system, maintained by the Massachusetts Water Resources Authority (MWRA). At in length, it is one of the longest aqueduct tunnels in the world being mile (0.8 km) shorter than the Hetch Hetchy Aqueduct. == Physical characteristics == Water from the capacity Quabbin Reservoir flows through the Quabbin Aqueduct from the northeast side of the Quabbin, up a slope to the Ware River Diversion in South Barre, Massachusetts, down again to the Wachusett Reservoir, and then through a power station near the Oakdale section of West Boylston, Massachusetts. This upward and downward flow occurs by natural siphon action, with the high point in the siphon being at the Ware River Diversion. The water surface at the Quabbin Reservoir is about 524 feet (159.7 m) above Mean Sea Level (MSL). The water surface at the Wachusett Reservoir is about 384 feet (117.1 m) above MSL, and the water surface at the Ware River Diversion is about 660 feet (201 m) higher than MSL.
