| Abstract: | Extensive flooding of streams in Chautauqua County, N.Y., on August 7-8, 1979, after severe thunderstorms, resulted in one death and millions of dollars worth of property damage. Severe flooding was reported on Canadaway Creek in Fredonia, where the peak discharge was computed to be 12,000 cubic feet per second. The recurrence interval of this discharge is estimated to be greater than 100 years (exceedance probability less than 0.01). A hydraulic analysis of the flood in Fredonia indicated that a debris jam at the Water Street bridge caused the water level (as determined from floodmarks) immediately upstream from the bridge to be 2.9 feet higher than level computed for unobstructed (without debris) flow conditions. The 100-year flood discharge at the Water Street bridge is computed to be 5,280 cubic feet per second, and the corresponding water level just upstream from the bridge (under unobstructed flow conditions) is 5.9 feet lower than the level observed during the August 7-8, 1979 flood.
