by Delph E. Carpenter as the Commissioner for the State of Colorado, under
authority of and in conformity with the provisions of an Act of the General
Assembly of the State of Colorado, approved April 2, 1921, entitled "An Act
providing for the appointment of a commissioner on behalf of the State of
Colorado to negotiate a compact or agreement between the States of Colorado and
New Mexico respecting the use and distribution of the waters of the La Plata
River and the rights of said States thereto, and making an appropriation
therefor.", the same being Chapter 244 of the Session Laws of Colorado, 1921,
and signed by Stephen B. Davis, Jr., as the Commissioner for the State of New
Mexico, under legislative authority, which said compact is as follows:
La Plata River Compact
The State of Colorado and the State of New Mexico, desiring to provide for
the equitable distribution of the waters of the La Plata River and to remove
all causes of present and future controversy between them with respect thereto,
and being moved by considerations of interstate comity, pursuant to Acts of
their respective Legislatures, have resolved to conclude a compact for these
purposes and have named as their commissioners:
Delph E. Carpenter, for the State of Colorado; and Stephen B. Davis, Jr.,
for the State of New Mexico; who have agreed upon the following Articles:
Article I
The State of Colorado, at its own expense, shall establish and maintain
two permanent stream-gauging stations upon the La Plata River for the purpose
of measuring and recording its flow, which shall be known as the Hesperus
Station and the Interstate Station, respectively.
The Hesperus Station shall be located at some convenient place near the
village of Hesperus, Colorado. Suitable devices for ascertaining and recording
the volume of all diversions from the river above Hesperus Station, shall be
established and maintained (without expense to the State of New Mexico), and
whenever in this compact reference is made to the flow of the river at Hesperus
Station, it shall be construed to include the amount of the concurrent
diversions above said station.
The Interstate Station shall be located at some convenient place within
one mile of, and above or below, the interstate line. Suitable devices for
ascertaining and recording the volume of water diverted by the Enterprise and
Pioneer Canals, now serving approximately equal areas in both States, shall be
established and maintained (without expense to the State of New Mexico), and
whenever in this compact reference is made to the flow of the river at the
Interstate Station, it shall be construed to include one-half the volume of the
concurrent diversions by such canals, and also the volume of any other water
which may hereafter be diverted from said river in Colorado for use in New
Mexico.
Each of said stations shall be equipped with suitable devices for
recording the flow of water in said river at all times between the 15th day of
February and the 1st day of December of each year. The State Engineers of the
signatory States shall make provision for co-operating gauging at the two
stations, for the details of the operation, exchange of records and data, and
publication of the facts.
Article II
The waters of the La Plata River are hereby equitably apportioned between
the signatory States, including the citizens thereof, as follows:
1. At all times between the first day of December and the fifteenth day
of the succeeding February, each State shall have the unrestricted right to use
of all water which may flow within its boundaries.
2. By reason of the usual annual rise and fall, the flow of said river
between the fifteenth day of February and the first day of December of each
year, shall be apportioned between the States in the following manner:
(a) Each State shall have the unrestricted right to use all the waters
within its boundaries on each day when the mean daily flow at the Interstate
Station is one hundred cubic feet per second, or more.
(b) On all other days the State of Colorado shall deliver at the
Interstate Station a quantity of water equivalent to one-half of the mean flow
at the Hesperus Station for the preceding day, but not to exceed one hundred
cubic feet per second.
3. Whenever the flow of the river is so low that in the judgment of the
State Engineers of the States, the greatest beneficial use of its waters may be
secured by distributing all of its waters successively to the land in each
State in alternating periods, in lieu of delivery of water as provided in the
second paragraph of this article the use of the waters may be so rotated
between the two States in such manner for such periods, and to continue for
such time as the State Engineers may jointly determine.
4. The State of New Mexico shall not at any time be entitled to receive
nor shall the State of Colorado be required to deliver any water not then
necessary for beneficial use in the State of New Mexico.
5. A substantial delivery of water under the terms of this Article shall
be deemed a compliance with its provisions and minor and compensating
irregularities in flow or delivery shall be disregarded.
Article III
The State Engineers of the States by agreement, from time to time, may
formulate rules and regulations for carrying out the provisions of this
compact, which, when signed and promulgated by them, shall be binding until
amended by agreement between them or until terminated by written notice from
one to the other.
Article IV
Whenever any official of either State is designated to perform any duty
under this compact, such designation shall be interpreted to include the State
official or officials upon whom the duties now performed by such official may
hereafter devolve.
Article V
The physical and other conditions peculiar to the La Plata River and the
territory drained and served thereby constitute the basis for this compact, and
neither of the signatory States concedes the establishment of any general
principle or precedent by the concluding of this compact.
Article VI
This compact may be modified or terminated at any time by mutual consent
of the signatory States and upon such termination all rights then established
hereunder shall continue unimpaired.
Article VII
This compact shall become operative when approved by the Legislature of
each of the signatory States and by the Congress of the United States. Notice
of approval by the Legislatures shall be given by the Governor of each State to
the Governor of the other State, and the President of the United States is
requested to give notice to the Governors of the signatory States of approval
by the Congress of the United States.
IN WITNESS WHEREOF, The commissioners have signed this compact in
duplicate originals, one of which shall be deposited with the Secretary of
State of each of the signatory States.
Done at the city of Santa Fe, in the State of New Mexico, this 27th day of
November, in the year of our Lord One Thousand Nine Hundred and Twenty-Two.
Delph E. Carpenter,
Stephen B. Davis, Jr.
