Abstract:

Lowell Reservoir Dam is an earth embankment structure which forms five of the six sides of Lowell Reservoir. The total crest length of the embankments is 1,650 ft. The sixth side of the reservoir is formed by natural ground and is about 270 ft. long. The maximum height of the dam is 26 ft. at the south-east embankment. For the test flood it was assumed that there would be no outflow from the reservoir and it was found that the reservoir could contain the estimated probable maximum precipitation for a 72 hour duration storm without overtopping the dam. About 1.9 ft. of free-board would remain after the test flood event. The dam is judged to be in generally fair condition. The main concerns are the growth of brush and mature trees along the two southerly embankments, and the lack of a seismic analysis.
