Daily gage heights kept at the Niles Damfrom 1888 to 1900. At the Sunol Dam, which succeeded theNiles Dam as the point of diversion of the Ala-meda waters in 1900, dailj^ gage heights, dur-ing low water, and more often during floodshave been taken to date. These two dams were built primarily for di-version purposes and not for stream gaging. At Calaveras particular attention was paidto stream gagings. Available measurementswere taken from 1898 to 1904 by Mr. GeorgeHadsell, and from 1904 to 1908 under the di-rection of Mr. Cyril Williams, Jr., and during1910-11 and 1912 by Mr. P. F. Jones.
