Twenty Years' Run-Off, at Holyoke, Mass., of the Connecticut River

While Hydraulic Engineer of the Holyoke Water Power Company, 1879-1889, the writer instituted a system of keeping a daily record of the discharge of the Connecticut River at Holyoke, which was continued, after his departure, by his old-time assistant and successor, A. F. Sickman, Assoc. M. Am. Soc. C. E., until a full 20 years' record had been obtained, 1880 to 1899, inclusive. The record could not be continued because in 1900 the new stone dam of the company flowed the water back on the old dam, and, by causing irregularity of flow over both dams, made further weir gaugings at these dams impossible. It seems desirable that the record of these 20 years' gaugings should be published in permanent form, so as to become, and remain, available to engineers, and the Holyoke Water Power Company having kindly furnished them, they are herewith given.
