Changes in surface-water hydrology, Platte River basin in Colorado, Wyoming, and Nebraska upstream from Duncan, Nebraska

Abstract

The North Platte and Platte Rivers in western and central Nebraska have undergone significant changes in surface-water hydrology since the latter part of the 19th century. The South Platte River in Colorado and Nebraska has undergone much less change during the same period. This report presents an analysis of the changes in surface-water resources in the Platte River basin in Colorado, Wyoming, and Nebraska upstream from Duncan, Nebraska, an area of 157,700 square kilometers.
