Abstract:

The economic analysis and final design of the 120 MW hydro-electric development on Dinkey Creek, a tributary of the North Fork of the Kings River in the Central Valley of California, requires a detailed simulation of the reservoir operation to determine the energy production and an in-depth flood study to derive the spillway design flood for the project. The operation study incorporated all permit requirements. A detailed flood study was performed. Rainfall and snowpack as well as temperature and solar insolation data in the area were used together with recorded streamflows to develop a unit hydrograph for the watershed. Hydrometeorological Report No. 36 published by the U. S. National Weather Service (formerly known as the U. S. Weather Bureau) temperature sequence for the derivation of the spillway design flood for the project.
