Republican River Compact
The states of Colorado, Kansas, and Nebraska, parties signatory to this compact (hereinafter referred to as Colorado, Kansas, and Nebraska, respectively, or individually as a state, or collectively as the states), having resolved to conclude a compact with respect to the waters of the Republican River Basin, and being duly authorized therefor by the Act of the Congress of the United States of America, approved August 4, 1942, (Public No. 696, 77th Congress, chapter 545, 2nd Session) and pursuant to acts of their respective legislatures have, through their respective governors, appointed as their commissioners:
M. C. Hinderlider, for Colorado
George S. Knapp, for Kansas
Wardner G. Scott, for Nebraska
who, after negotiations participated in by Glenn L. Parker, appointed by the President as the representative of the United States of America, have agreed upon the following articles:
Article I
The major purposes of this compact are to provide for the most efficient use of the waters of the Republican River Basin (hereinafter referred to as the “Basin”) for multiple purposes; to provide for an equitable division of such waters; to remove all causes, present and future, which might lead to controversies; to promote interstate comity; to recognize that the most efficient utilization of the waters within the Basin is for beneficial consumptive use; and to promote joint action by the states and the United States in the efficient use of water and the control of destructive floods.
The physical and other conditions peculiar to the Basin constitute the basis for this compact, and none of the states hereby, nor the Congress of the United States by its consent, concedes that this compact establishes any general principle or precedent with respect to any other interstate stream.
Article II
The Basin is all the area in Colorado, Kansas, and Nebraska, which is naturally drained by the Republican River, and its tributaries, to its junction with the Smoky Hill River in Kansas. The main stem of the Republican River extends from the junction near Haigler, Nebraska, of its North Fork and the Arikaree River, to its junction with Smoky Hill River near Junction City, Kansas. Frenchman Creek (River) in Nebraska is a continuation of Frenchman Creek (River) in Colorado. Red Willow Creek in Colorado is not identical with the stream having the same name in Nebraska. A map of the Basin approved by the commissioners is attached and made a part hereof.
The term “Acre-foot,” as herein used, is the quantity of water required to cover an acre to the depth of one foot and is equivalent to forty-three thousand, five hundred sixty (43,560) cubic feet.
The term “Virgin Water Supply,” as herein used, is defined to be the water supply within the Basin undepleted by the activities of man.
The term “Beneficial Consumptive Use” is herein defined to be that use by which the water supply of the Basin is consumed through the activities of man, and shall include water consumed by evaporation from any reservoir, canal, ditch, or irrigated area.
Beneficial consumptive use is the basis and principle upon which the allocations of water hereinafter made are predicated.
Article III
The specific allocations in acre-feet hereinafter made to each state are derived from the computed average annual virgin water supply originating in the following designated drainage basins, or parts thereof, in the amounts shown:
North Fork of the Republican River drainage basin in Colorado, 44,700 acre-feet;
Arikaree River drainage basin, 19,610 acre-feet;
Buffalo Creek drainage basin, 7,890 acre-feet;
Rock Creek drainage basin, 11,000 acre-feet;
South Fork of the Republican River drainage basin, 57,200 acre-feet;

(a)

Any beneficial consumptive uses by the United States, or those acting by or under its authority, within a state, of the waters allocated by this compact, shall be made within the allocations hereinabove made for use in that state and shall be taken into account in determining the extent of use within that state.

(b)

The United States, or those acting by or under its authority, in the exercise of rights or powers arising from whatever jurisdiction the United States has in, over and to the waters of the Basin shall recognize, to the extent consistent with the best utilization of the waters for multiple purposes, that beneficial consumptive use of the waters within the Basin is of paramount importance to the development of the Basin; and no exercise of such power or right thereby that would interfere with the full beneficial consumptive use of the waters within the Basin shall be made except upon a determination, giving due consideration to the objectives of this compact and after consultation with all interested federal agencies and the state officials charged with the administration of this compact, that such exercise is in the interest of the best utilization of such waters for multiple purposes.

(c)

The United States, or those acting by or under its authority, will recognize any established use, for domestic and irrigation purposes, of the waters allocated by this compact which may be impaired by the exercise of federal jurisdiction in, over, and to such waters; provided, that such use is being exercised beneficially, is valid under the laws of the appropriate state and in conformity with this compact at the time of the impairment thereof, and was validly initiated under state law prior to the initiation or authorization of the federal program or project which causes such impairment.
