Yampa/White River Basin

The Yampa/White Basin covers roughly 10,500 square miles (10 percent of the state’s area) in northwest Colorado and south central Wyoming. In addition to the Yampa and White Rivers, major tributaries include Green River, Little Snake River, Elk River, and Piceance Creek. While the North Platte is part of the Platte river system, for administration purposes, it is included with the Yampa and White.

Compact Facts
  • Colorado River Compact of 1922:  As a tributary to the Colorado River, the Yampa/White Basin is affected by Colorado River compacts. The Colorado River Compact allocates 7.5 million acre-feet (AF) of consumptive use annually to:
  1. the Upper Colorado River Basin (those parts of Arizona, Colorado, New Mexico, Utah, and Wyoming above Lee Ferry, Arizona), and
  2. the Lower Colorado River Basin (those parts of Arizona, California and Nevada below Lee Ferry, Arizona).
  • Upper Colorado River Basin Compact of 1948:  The Upper Colorado River Basin Compact allocates the 7.5 million AF apportionment of consumptive uses available to the Upper Basin as follows:
    • Arizona – 50,000 AF/year
    • Colorado – 51.75%
    • Utah – 23%
    • Wyoming – 14%
    • New Mexico – 11.25%
