Buffalo Metropolitan Area, New York. Water Resources Management Study. Tonawanda Creek Watershed. Interim Flood Management Study

摘要

This report recommends construction of the Batavia Reservoir Compound modified alternative to provide flood damage reduction in the Tonawanda Creek Watershed, N.Y. The alternative consists of two shallow detention reservoirs (normally dry) arranged in series. The reservoirs would be formed by construction of two earth dams. Each dam would have principle outlet works comprised of side-by-side conduits; five for the upper dam and four for the lower, with dimensions of 11 feet by 11 feet. Each conduit would be equipped with an electrically operable gate and provisions for manual operation. The spillways of both dams would be riprapped on the upstream and downstream and crets. The amount of reservoir flood control stroage and operation of the selected plan were developed to meet the planning objectives of the study. The degree of protection afforded by the plan is approximately 500-year in the city of Batavia and variable downstream.
