Beach developed plans for the reconstruction of the
Muskingum River locks and
dams soon after
Ohio ceded the state-built improvements to the federal government in 1887. From 1894 to 1901 he worked on public improvements in the
District of Columbia, serving as Engineer Commissioner there in 1898–1901. As Detroit District Engineer in 1901–05, he oversaw
harbor improvements as far west as
Duluth. Beach supervised improvements along the Louisiana
Gulf Coast in 1908–12 and in
Baltimore in 1912–15. He also oversaw the entire Gulf Division in six of those seven years and the Central Division in 1915–20. In the latter capacity and as
Chief of Engineers, he oversaw construction of the huge
Wilson Locks and Dam on the
Tennessee River. Beach also served on the
Mississippi River Commission and the Board of Engineers for Rivers and Harbors. After his four-year tour as Chief of Engineers, he retired on June 18, 1924. After retirement, General Beach served as consulting engineer for various business interests in the United States and Mexico. He was President of the
American Society of Military Engineers, and a member of the
International Water Commission from 1924 to 1930. Beach died in
Pasadena, California on April 2, 1945. He was interred at
Arlington National Cemetery beside his wife Anna May (Dillon) Beach (1861–1934) on January 29, 1946. ==References==
