Abstract
Flood profiles covering the main stem to river mile 11.0 (kilometer 17.7) of the White River in Chelan County, Wash., were developed in a 3-year field study (1970-72) in cooperation with the State of Washington Department of Ecology. Flood-frequency curves based on an average of a regional computation and a Log-Pearson Type III analysis of 18 years of record indicate that the 100-year flood will have a discharge of about 6,600 cubic feet per second, or about 186 cubic meters per second,at river mile 6.4.or kilometer 10.3. Discharge of a 50-year flood was computed to be about 6,300 cubic feet per second, or about 178 cubic meters per second. The greatest flood discharge during the study period occurred on June 10, 1972, and was 5,310 cubic feet per second, or about 150 cubic meters per second; such a discharge has a recurrence interval of 4 years. Most of the flood plain of the White River probably is inundated during a 100-year flood.
