Earth dams, a study

by Burr Bassell

Combined Rock-fill and Earth Dam.

[Fig. 30] shows a section of the Upper Pecos River Dam near Eddy, N. M.

This dam is quite fully described by Mr. Jas. D. Schuyler, in his recent book on “Reservoirs for Irrigation, Water-Power and Domestic Water-Supply,” and need not be mentioned in this paper, further than to call attention to the combination of rock-fill and earth which constitutes its particular type of construction. This type of dam is believed to be for many localities a very good one, but up to the present time has only been adopted for dams of moderate height, under 60 ft.
