Frank E. Stovicek, 64, a hydraulic research engineer at the Department of Transportation and a former president of the Mount Pleasant Citizens Association here, died at Washington Hospital Center Saturday of complications following a stroke.

Mr. Stovicek was born in Prague, Czechoslovakia, and earned a degree in engineering at Charles University there. After World War II, he was with U.S. Army Intelligence in Europe for five years. He came to the United States in 1955, and settled in Washington.

He went to work for the Commerce Department and later transferred to Transportation. Among his duties there, he was contract manager on a report on flood and flow data on 1,000 small streams in 30 states.

In addition to his work with the Mount Pleasant Citizens Association, Mr. Stovicek was a member of Sokol of Washington, a Czechoslovakian cultural and physical education organization. He introduced children's classes in gymnastics to the local group.

About seven years ago, he bought an abandoned farm in Hustontown, Pa., and raised cows and horses there.

Survivors include his wife, Louise, of the home in Washington, and their two children, Helen and Frank, also of the home; two children by an earlier marriage that ended in divorce, Colleen and Lauren, both of Silver Spring, and two children in Czechoslovakia, Petra and Libuse, by another marriage that also ended in divorce.
