The dam was built in 1906 as part of a water supply. Dogs are not allowed in the parks because the 65 billion gallon reservoir is a water supply. The reservoir "covers 108 square miles with 37 miles of shoreline." [

"At the time of construction, the
Wachusett Reservoir was the largest in
the world. It remains a great engineering
feat and is one of the few unfiltered
water supplies in the country.

"The Wachusett Dam maintains the honor of being the largest hand built gravity dam in the world. Constructed of granite masonry, the dam stretches 944’ [288m] across." The height of the dam is 115' (35m) above ground and 112' (34m) below. It tapers from 22.5' (6.9m) at the top to 185' (56m) at the bottom. The spillway is 452' (138m) long. |
Did the power plant quit running when they turned the tailrace into a fountain?
Actually, there was no outlet at the base of the dam because the spillway is on the side and the normal flow is diverted into an aqueduct as a water supply. This map also shows were the trestle crossed the river when the Boston & Maine tracks were rerouted around the dam site.

The top middle diagram shows that there is more of the dam underground than above.

In 1907, because of a landslide, they had to build a 2-mile (3.2km) long dike.
