Dow A. Buzzell, 86, a retired hydraulic engineer with the Army Corps of Engineers who worked on hydroelectric projects in this country and abroad and who was a former Arlington resident, died Sept. 11 at Bowman's Care Center in Ormond Beach, Fla. He had Parkinson's disease.

Mr. Buzzell worked for the Federal Power Commission here after moving to this area in about 1940. He joined the Corps of Engineers during World War II and was head of the structures section in the civil works division when he retired in 1956.

Born in Plattsmouth, Neb., he earned a bachelor's degree in engineering from the University of Nebraska in 1915. He worked for an engineering firm in Boston before moving to this area.

After retiring, Mr. Buzzell joined the international architectural and engineering firm of Tippetts, Abbett, McCarthy, now Tippetts, Abbett, McCarthy, Stratton, and worked on hydroelectric projects in South America and in Taiwan.

A specialist on dams, he was involved in the design, planning and construction of 18 hydroelectric projects during his career.

Mr. Buzzell served in the Air Corps as a balloon instructor during World War I.

He had lived in Ormond Beach since 1960.

Survivors include his wife, the former Grace Blomquist of Ormond Beach; two sons, Donald of Norwalk, Conn., and Robert of Wellesley, Mass., seven grandchildren and one great-grandson.

The family suggests that expressions of sympathy be in the form of contributions to the Ormond Memorial Hospital, Ormond Beach, Fla.
