Hydrologic data pertaining to the 200,000 square mile Yukon River basin above the proposed Rampart Canyon Dam in Alaska are analyzed for maximum possible flood to be used in spillway design. Short periods of records from a minimum number of stream gaging stations and climatological stations are utilized. Snowmelt equations developed by the Cooperative Snow Investigations program of the Army and Weather Bureau are applied. Probable maximum precipitation theories developed by the hydrometeorological section USWB are used on the 21 principal tributaries, to determine the possible maximum flood. All data was processed by electronic digital computer to develop the storage and flood routing equations. Tables and graphs illustrate the reconstructed hydrographs.Discussion by R. E. Lindgren.
