Hydro-power peaking and pondage by computer

Abstract

THE hydroelectric development of the lower and middle Columbia River is unique: its exclusive development by low-head run-of-river projects is not encountered elsewhere on a river of this magnitude. From tailwater at Bonneville dam to the Chief Joseph forebay at 946-feet elevation, virtually all of the head is being developed by a series of overlapping hydro projects. A similar development is being planned for the lower Snake River up to its confluence with the Salmon River (Fig. 1). Projects existing or under construction are indicated by the solid symbols; those planned for future development by the dashed symbols.
