The rock-fill dam described in this paper was designed by the writer for George Crocker, Esq., to impound a gravity water supply for his estate at Darlington, near Ramseys, New Jersey.
The site selected was at the head of a ravine where the hills widened out, forming a natural bed for a lake. The site was about 250 ft. above the farm buildings in the valley of the Ramapo River, and about 65 ft. above the point selected for the new residence.
The small brook running down the ravine had a probable summer average flow of from 9 to 10 cu. ft. per second. During extreme freshets, this flow was increased rapidly, probably to sixty or seventy fold, as, mving to the rocky formation of the hills in this locality, the runoff and rainfall are nearly equal.
