Upstream portals of outlet conduits for Englewood Dam. The conduits are 709 feet long, 13 feet wide each, and have a temporary vertical inside diameter of 22 1/2 feet. This gives them a large capacity for handling flood water during construction. After the earthwork is completed the vertical diameter will be reduced to 10 1/2 feet by filling the bottom portion with earth, and placing a concrete floor at the proper elevation. At left, the placing of earth in the portion of the dam east of the Stillwater River, is seen in progress. The cross dike along the river, for controlling the hydraulic fill beyond, is being built up by a dragline excavator, the materials being brought to the site by trains of dump cars. Dam will be 4716 feet long average width at base 739 feet; height above valley floor 110.5 ft.; height of crest above top of concrete outlet conduits 107 ft.; max. discharge capacity (basin full to spillway level) 12,000 sec. ft.; concrete in entire outlet structure 19,000 cu. yds, July 28, 1919

Series Scope and Contents

From the Series:

The photographs in this series are pasted in albums with Lippincott’s handwritten numbers and captions. When this collection was first processed in 1999, processing staff transcribed photograph titles directly from these handwritten captions. The photo album titles were also transcribed from Lippincott’s own titles.

Several photograph titles reference outdated geographic names that include racial slurs. UCR Library has chosen to keep and add context to Lippincott’s use of harmful language in these titles. The titles reflect the place names in use at the time the photographs were taken. They also give information about how Lippincott organized and annotated his photographs. In 2022, notes on specific photographs were added to the finding aid for further context, including current place names where available. Photographs vary in size.

Further particulars are as follows: "Buttes Dam photographs", one album, undated; "Colorado River trip photographs", one album, dated December 1925; "Henshaw Dam - Escondido Ditch photographs", two albums, photos dated 1922 to 1929; "Klamath Project photographs - California, Oregon", two albums, dated 1906; "J.B.
