Colorado Water History

A guide to finding and using historical information about water in Colorado and beyond

Welcome!

Colorado is the Headwaters State. Four major rivers begin in its Rocky Mountains: the Colorado, the Rio Grande, the Arkansas, and the Platte. Because all of these flow out of Colorado to other equally arid states, competition for this limited supply occurs both within the state and across its borders.

The development and use of water, and the politics and law that accompany it--not to mention people and organizations with diverse needs that use it--have created a complex history. That history touches on agriculture, engineering, wildlife, recreation, and much more.

Researching Colorado's complex water history can be daunting! The resources presented in this guide will help you navigate water history from Colorado's headwaters to the state's borders--and beyond.

This guide is brought to you by the Water Resources Archive, the best place in the state to begin learning about the history of Colorado's most precious resource.

Historical Highlight

In 1917 at age 74, Prucius W. Putnam recollected his earlier days in the South Platte Watershed. Such statements were collected by Colorado water lawyer Delph Carpenter and led to the South Platte Compact of 1923.
