摘要：	The Applegate Dam project.located in southwestern Oregon, provides flood control storage and includes facilities for upstream fish migration and temperature rantrol of normal project releases. This report presents the results of model studies used in the final design of the project spillway and flood control outlet. Tests with the spillway model Indicated that the originally designed spproach channel invert could beransed 20 feet and still maintain satisfactory spillway operation.The reduction in approach-chanel depth resulted in a considerable decrease in excavation costs. The model was used to evaluate the performance of the spillway plunge pool. Initial operation of the outlet model revealed the existence of an unacceptable roostertail emanating from the nose of the splitter wall separating the two outlet entrances.The model was used to develop a pier modification which reduced the roostertail to acceptable limits.The report stilling basin which consists of aunique,dual-chamber hydraulic-jump basin which also functions as an entrance pool for the fish passage facility.
