Filling and Emptying System. Little Goose Lock. Snake River, Washington, Hydraulic Model Investigation.

Abstract

Little Goose Lock, located on the Snake River 70.3 miles above its junction with the Columbia River at Pasco, Washington, is 86 ft wide by 675 ft long and is designed for a maximum lift of 101 ft. The split-lateral hydraulic system, with floor culverts on 50-ft centers, is unique because both intake manifolds and both longitudinal culverts are in the right wall. This design was expected to reduce construction costs about $240,000. Portions of the forebay and tailrace and all elements of the lock chamber and hydraulic system were reproduced in a 1:25-scale model. The proposed arrangements of lateral culverts (five floor laterals supplied by each longitudinal culvert) was not satisfactory. Average and individual maximum longitudinal forces with an 8-barge tow were less than the allowable force of 5 tons; however transverse forces were excessive (7.5 tons at upstream end and 8.1 tons at downstream end).
