Law of the river
• Law of the River

• The Law of the River is a complex body of laws, court
cases and regulations that control use of Colorado River
water and the operation of its dams.
• In the 1800s, states diverted water from the Colorado
River and its tributaries without restrictions. As the
diversions increased, a long battle over apportionment
evolved. Today, the Colorado River is probably the most
controlled, controversial and litigated river in the world.

In 1922, the seven US
basin states and two
Mexican states began
negotiations that led
to the Colorado River
Compact.
The Colorado River Compact of
1922
 The cornerstone of the "Law of the River“

 defined the relationship between the upper basin states,
where most of the river's water supply originates, and the
lower basin states, where most of the water demands were
developing
 Secretary of Commerce Herbert Hoover suggested the basin
be divided into an upper and lower half, with each basin
having the right to develop and use 7.5 million acre-feet (maf)
of river water annually. This approach reserved water for
future upper basin development and allowed planning and
development in the lower basin to proceed.

The measurements used during the negotiations and subsequent
allocation period were taken during two high water periods and do
not factor in droughts.
Laws, contracts and documents which are part
of the "Law of the River"



The Mexican Water Treaty of 1944 - Committed 1.5 maf of the river's annual flow
to Mexico.
Colorado River Storage Project of 1956 - Provided a comprehensive Upper Basinwide water resource development plan and authorized the construction of Glen
Canyon, Flaming Gorge, Navajo and Curecanti dams for river regulation and power
production, as well as several projects for irrigation and other uses.
The Criteria for Coordinated Long-Range Operation of Colorado River Reservoirs
of 1970 (amended March 21, 2005) - Provided for the coordinated operation of
reservoirs in the upper and lower basins and set conditions for water releases from
Lake Powell and Lake Mead.
U.S.-Mexico International Boundary and Water Commission of 1973 - Required
the U.S. to take actions to reduce the salinity of water being delivered to Mexico at
Morelos Dam.
The Colorado River Basin Salinity Control Act of 1974 - Authorized desalting and
salinity control projects, including the Yuma Desalting Plant, to improve Colorado
River quality.
