FROM THE ANNUAL REPORT OF THE COCHITUATE WATER BOARD FOR 1852.

The Compensating Reservoirs, at Hopkinton and Marlborough, which were purchased and improved for the purpose of supplying Concord River with the water which had been withdrawn by retaining the natural flow of Lake Cochituate, are in good order. The quantity discharged from the Hopkinton Reservoir, from June 13 to November 14, was 912,796,300 gallons; and from the Marlborough, between July 14th and October 21st, it was 1,052,081,000 gallons,from both, 1,964,877,300 gallons. By calculation, the natural flow from the Lake was 735,229.294 gallons, during the abovementioned periods, being less than one-half what was discharged from the Reservoirs. And the quantity thus discharged during the months of July and August, the only months when any scarcity is felt at the Mills on the River, was about three and a half times the natural supply of the Lake. The rain-fall during the year, at the Marlborough, was 46.81 inches, and at the Hopkinton, 44.42 inches, as ascertained by rain guages, kept by the Superintendents of each.
