Morrow Point Dam
The 1960s saw a revival in the use of arch dam construction in the U.S. One of the most notable is the Morrow Point Dam, a feature of the Colorado River Storage Project, constructed in 1963-68. Described as an "engineer's dream," it is just 12 feet thick at its crest and 52 feet thick at its base. Other unusual features include an overhang on the downstream face, an undercut on the upstream face, and four large openings near the top of the dam for a spillway. In 1970, additional drilling and foundation grouting was done to extend the original grout curtain. The underground power plant has a total generating capacity of 120,000 kilowatts.
