Catalog Record
Avalon Reservoir (New Mexico) Sedimentation Survey Data
Avalon Reservoir Sedimentation Survey Data. The primary purpose of this type of survey is to determine the present storage-elevation relationship of the reservoir and possible change in storage due to sedimentation. Avalon Reservoir is associated with Avalon Dam. Reservoir sedimentation surveys typically contain a survey report, area-capacity (ACAP) table, and geospatial data.

Location Description
Avalon Dam is located on the Pecos River 5 miles north of Carlsbad, New Mexico. The dam is a zoned earthfill structure that was constructed by private interests in 1888. The dam washed out in 1893 and, after reconstruction, was washed out again in 1904 by the Pecos River flood. The Reclamation Service rebuilt the dam in 1907. The height of the dam was increased in 1912, and again in 1936. The dam now has a structural height of 60 feet and a volume of 202,000 cubic yards. This is an earthfilled structure 1,360 feet long and 53 feet high. There are three spillways and an outlet works. The original reservoir storage capacity was 7,000 acre-feet; a 1996 resurvey showed a capacity of 4,466 acre-feet at the top of conservation pool.
