Interstate River Compacts: Topic Breakdown

True copy, Colorado River CompactThe 1922 Colorado River Compact was the first interstate agreement to determine how states would share a stream. The seven basin states joined together to negotiate the legal agreement that now serves as the foundation of the "Law of the River." Several similar compacts followed for the state of Colorado as well as other western states, and the idea has extended to the eastern U.S., which has very different water laws, as well as to other countries.

Colorado water lawyer Delph Carpenter proposed the compact idea in 1920 and subsequently drafted and negotiated the Colorado River Compact and others. Understanding the background of the idea and its evolution is an important part of understanding western water issues.

Document: True copy, Colorado River Compact, 1922. From the Papers of Delph E. Carpenter and Family.
