CHAPTER 3 - WATER RIGHTS; ADMINISTRATION AND CONTROL

ARTICLE 1 - GENERALLY

41-3-101. Nature of water rights and beneficial use.

Awater right is a right to use the water of the state, when such use has beenacquired by the beneficial application of water under the laws of the staterelating thereto, and in conformity with the rules and regulations dependentthereon. Beneficial use shall be the basis, the measure and limit of the rightto use water at all times, not exceeding the statutory limit except as providedby W.S. 41-4-317. In addition to any beneficial use specified by law or ruleand regulation promulgated pursuant thereto, the use of water for the purposeof extracting heat therefrom is considered a beneficial use subject to priorrights. Water being always the property of the state, rights to its use shallattach to the land for irrigation, or to such other purposes or object forwhich acquired in accordance with the beneficial use made for which the rightreceives public recognition, under the law and the administration provided thereby.Water rights for the direct use of the natural unstored flow of any streamcannot be detached from the lands, place or purpose for which they areacquired, except as provided in W.S. 41-3-102 and 41-3-103, pertaining to achange to preferred use, and except as provided in W.S. 41-4-514.

41-3-102. Preferred uses; defined; order of preference.

(a) Water rights are hereby defined as follows according touse: preferred uses shall include rights for domestic and transportationpurposes, steam power plants, and industrial purposes; existing rights notpreferred, may be condemned to supply water for such preferred uses inaccordance with the provisions of the law relating to condemnation of propertyfor public and semi-public purposes except as hereinafter provided.

(b) Preferred water uses shall have preference rights in thefollowing order:

(i) Water for drinking purposes for both man and beast;

(ii) Water for municipal purposes;

(iii) Water for the use of steam engines and for general railwayuse, water for culinary, laundry, bathing, refrigerating (including themanufacture of ice), for steam and hot water heating plants, and steam powerplants; and

(iv) Industrial purposes.

(c) The use of water for irrigation shall be superior andpreferred to any use where water turbines or impulse water wheels are installedfor power purposes; provided, however, that the preferred use of steam powerplants and industrial purposes herein granted shall not be construed to givethe right of condemnation.

41-3-103. Preferred uses; procedure for change of use.

Whereit can be shown to the board of control under the provisions hereof, that apreferred use is to be made, the procedure for a change of such use shall embracea public notice, an inspection and hearing if necessary by and before theproper division superintendent, a report of such superintendent to the board ofcontrol, and an order by said board. If the change of use is approved, justcompensation shall be paid and under the direction of the board, properinstruments shall be drawn and recorded.

41-3-104. Procedure to change use or place of use.

(a) When an owner of a water right wishes to change a waterright from its present use to another use, or from the place of use under theexisting right to a new place of use, he shall file a petition requestingpermission to make such a change. The petition shall set forth all pertinentfacts about the existing use and the proposed change in use, or, where a changein place of use is requested, all pertinent information about the existingplace of use and the proposed place of use. The board may require that anadvertised public hearing or hearings be held at the petitioner's expense. Thepetitioner shall provide a transcript of the public hearing to the board. Thechange in use, or change in place of use, may be allowed, provided that thequantity of water transferred by the granting of the petition shall not exceedthe amount of water historically diverted under the existing use, nor exceedthe historic rate of diversion under the existing use, nor increase thehistoric amount consumptively used under the existing use, nor decrease thehistoric amount of return flow, nor in any manner injure other existing lawfulappropriators. The board of control shall consider all facts it believespertinent to the transfer which may include the following:

(i) The economic loss to the community and the state if the usefrom which the right is transferred is discontinued;

(ii) The extent to which such economic loss will be offset bythe new use;

(iii) Whether other sources of water are available for the newuse.

(b) In all cases where the matter of compensation is indispute, the question of compensation shall be submitted to the proper districtcourt for determination.

41-3-105. Repealed by Laws 1983, ch. 167, 2.

41-3-106. Procedure to exchange water; delivery of water underexchanges; approval of state engineer; enforcement of exchanges.

(a) Any appropriator owning a valid water right in and to theuse of the ground, surface or reservoir waters of the state, where the sourceof the appropriation is at times insufficient to fully satisfy suchappropriation, or better conservation and utilization of the state's water canbe accomplished, or the appropriator can develop appropriable water but cannoteconomically convey it to its point of use, may petition the state engineer foran order allowing an exchange and the use of stored, direct flow, or groundwater from another source. If such an appropriator arranges by agreement withanother appropriator for the delivery and use of either stored, direct flow, orground water from another source, the exchange agreement shall accompany thepetition.

(b) Exchanges may be allowed among any combination of directflow, storage, and groundwater rights. Petitions for exchanges shall beaccompanied by such maps, plans or other information as may be required by thestate engineer. The proper filing and recording fees shall accompany thepetition.

(c) No exchange shall be allowed until the state engineer hasentered an order granting the exchange. Documents drawn in connection withexchanges may be recorded in one (1) or more counties where any part of theland involved is situated. No exchange may be terminated without the issuanceof an order approving termination, unless the order allowing the exchangeprovides for termination on a specified date.

(d) It is the policy of the state to encourage exchanges. Thestate engineer shall not issue an exchange order if it appears that theproposed exchange would adversely affect other appropriators, or if theproposed exchange would, in the opinion of the state engineer, be too difficultto administer or would be adverse to the public interest. All exchanges aresubject to the requirements of beneficial use and equality of water exchanged,and no exchange will be allowed unless a sufficient quantity of makeup water isintroduced to replace the water diverted and withdrawn under the exchange. Inmaking the determination of equality and sufficiency of the makeup waterintroduced, the state engineer may consider relative consumptive uses andtransmission losses.

(e) Any water made available to an appropriator by reason ofany exchange agreement shall be delivered for the use of the appropriator inaccordance with the order allowing the exchange, and its use is withoutprejudice to, but in enjoyment of, the rights of all appropriators under theiroriginal appropriations.

(f) Performances of each exchange shall be enforced by thewater administration officials of the state in accordance with the terms andconditions of the order allowing the exchange. The state engineer may adoptsuch rules and regulations as are necessary to enable him to efficientlyadminister this section.

(g) The state engineer shall assess a fee not to exceed fiftydollars ($50.00) for his review, and approval of exchange petitions. This fee shallaccompany an exchange petition and shall be retained and deposited whether thepetition or request is approved or denied.

41-3-107. Submerged lands; petition for change of water rights;conditions; hearing; fees.

(a) The state board of control may, upon the written petitionof the owners of an adjudicated water right, or water rights appurtenant tolands submerged by the construction of reservoirs in the state of Wyoming,issue amended certificates of appropriation of water and change the point ofdiversion and means of conveyance for such adjudicated appropriations of waterfor the irrigation of other lands in the state of Wyoming outside of thereservoir basin in lieu of the submerged lands, without loss of priority; provided:

(i) The appropriation shall be from the same source of supply;

(ii) The irrigated acreage shall include not only new landwithin the state of Wyoming having no original direct flow water right but alsolands within the same drainage area having water rights from another source andwhich have a need for supplemental water, but in no event shall such right anduse so changed exceed in amount of water that of the rights which are beingchanged;

(iii) Such change of water rights be made within five (5) yearsfrom the date that construction of the reservoir dam has been completed. Ifsuch change is not applied for by the owner or his successors in interestwithin the five (5) year period such water rights shall become automaticallyabandoned and the water shall be distributed in order of priority on thestream. Such automatic abandonment shall apply only to lands inundated at andbelow the high water line of reservoirs. The board of control shall enter anorder abandoning the water rights upon a determination that an abandonment hasoccurred;

(iv) The change can be made only on condition that it does notinjuriously affect the rights of other Wyoming appropriators.

(b) After receipt of a petition for such change the state boardof control shall cause a public hearing to be held on the petition before thesuperintendent of the water division in which such appropriation is located,with notice of the hearing to be advertised in at least one (1) issue of anewspaper having general circulation in the community where the water rightinvolved is located. The petitioner shall pay the cost of publication prior tothe time of hearing and shall provide a stenographic record of the proceedings,which shall be transmitted by the division superintendent to the state board ofcontrol with his report. A fee not to exceed fifty dollars ($50.00) forissuance and recording of each amended certificate of appropriation of watershall be collected by the state board of control at the time of filing of thepetition and the board shall also require a deposit of sufficient funds tocover the cost of preparing and recording a certified copy of the order of theboard granting the petition.

(c) The owners of lands coming under the provisions of thissection may sell or convey lands submerged or to be submerged by any suchreservoir with provisions in the deed or other conveyance that the water rightsappurtenant thereto may be detached and transferred as provided herein.

41-3-108. Lands taken out of agricultural production or lands taken byeminent domain; retention of priority.

(a) Where lands are taken out of agricultural production as thenecessary result of acquisitions for railroad roadbed construction, highwayconstruction, mining or petroleum extraction operations or industrial siteacquisitions or lands taken by proceedings in eminent domain or which havebecome impracticable to irrigate by reason of any of the foregoing conditions,the owner of an affected water right may transfer the water right to other landsheld by the owner. The petition for the change in use, or change in place ofuse shall be properly filed within five (5) years of the date the land went outof production because of any of the conditions specified herein. Failure tofile the petition within five (5) years results in forfeiture of the rightexcept as otherwise provided.

(b) The petition for a change in use, or change in place ofuse, of a water right under this section shall retain its original date ofpriority.

(c) For a period of five (5) years after the effective date ofthis act, any appropriator whose land has been out of production for more thanfive (5) years may petition the board requesting transfer of the water rightsinvolved. The granting or denial of a petition under these circumstances iswithin the discretion of the board. The decision of the board may be appealedto the district court. The board may hold public hearings in connection with apetition being considered pursuant to this section. All costs in conjunction withthe hearing shall be borne by the petitioner.

Theprovisions of this act shall be valid notwithstanding the provisions of W.S.41-3-101.

41-3-110. Right to acquire temporary water rights for highway orrailroad roadbed construction or repair; application; restrictions; fee.

(a) Any person shall have the right to acquire by purchase,gift or lease the right to the use of water which may be embraced in anyadjudicated or valid unadjudicated water right, or any portion thereof, for aperiod of not to exceed two (2) years, for highway construction or repair,railroad roadbed construction or repair, drilling and producing operations, orother temporary purposes, on its own behalf or on behalf of its agents,employees or contractors: provided, that if the proposed use is to be forpublic highway construction or repair under a contract with the statedepartment of transportation, only the state transportation commission shallhave the authority to acquire the water; and the state transportationcommission shall have the sole and continuing responsibility for theacquisition, including the payment of all fees, royalties and otherconsideration for the use of and access to water and the right to acquire therights to use shall not be delegated to a construction contractor or otherthird party; and further provided, that any temporary transfer shall be allowedonly if no other appropriator is injured thereby.

(b) Before any right to such use shall become operative, anapplication must be made in writing on a form provided or designated by thestate engineer, with a copy of any conveyance or agreement provided, and itshall be filed in the office of the state engineer for his ratification andapproval. Upon approval by the state engineer, an order authorizing such useand designating the method, place, and period of use may be entered. No loss,abandonment or impairment of such water rights shall occur or attach as aresult of such change or use, except as provided by said conveyance oragreement and order of the state engineer, and upon termination of thetemporary diversion and use, as stated in the order, any affected right to theuse of water shall automatically be reinvested with all the rights, privilegesand uses, and purposes theretofore held and enjoyed.

(c) Only that portion of a water right so acquired which hasbeen consumptively used under the historical use made of the water right, maybe diverted by a temporary user. In determining the consumptive use of waterrights for the direct use of the natural unstored flow of any stream forirrigation purposes, the return flow from those rights shall be presumed to befifty percent (50%). In those situations where an assumption of fifty percent(50%) return flow would be significantly in error, the state engineer shallhave the prerogative of making a determination of the actual amount of returnflow, and the amount of water which can be diverted for the temporary useprovided herein shall be adjusted accordingly. The actual historic return flow,or the assumed return flow of fifty percent (50%) will be left in the streamfor the use of downstream appropriators. The foregoing formula and procedurefor the determination of consumptive use and return flow shall be limited tothis section and shall have no application to any other statute of the state ofWyoming. Nothing herein contained shall be treated or construed as changing theprior use of water held by said owner or owners and as provided by the laws ofthe state of Wyoming.

(d) The state engineer shall assess a fee not to exceed onehundred dollars ($100.00) for his review and approval of temporary wateragreements. This fee shall accompany the agreement application and shall beretained and credited to the general fund whether the agreement or request isapproved or denied.

41-3-111. Right to acquire temporary water rights for highway orrailroad roadbed construction or repair; right of owner who cannot satisfy infull his right during time of diversion.

Theowner of any permanent water right, whether prior or subsequent in priority tothat temporary right acquired by any person under this act who cannot satisfyin full his right during the time said temporary user is diverting water underits temporary water right shall have the absolute right upon demand being madeupon the appropriate state water commissioner to cause such diversion to beshut off until such time as said owner's water right is satisfied, or until itis proven that the shutting down of the diversion has no effect upon owner'sright.

41-3-112. Right to acquire temporary water rights for highway orrailroad roadbed construction or repair; wrongfully causing diversion to beshut down.

Itshall be unlawful for any person to wrongfully cause a diversion made under atemporary water right required under and by virtue of this act to be shutdown. Any violation of this section shall be punishable pursuant to W.S.41-3-616.

41-3-113. Supplemental supply water rights.

Asupplemental supply water right is defined as a permit or certificate ofappropriation for the diversion, from a stream, of water from a new source ofsupply for application to lands for which an appropriation of water from aprimary source already exists. Such supplemental supply permits or certificatesof appropriation may be allowed by the state engineer or the state board ofcontrol under such regulations or conditions as he or it may prescribe. The useand administration of presently existing rights for supplemental supplyappropriations or rights for supplemental supply appropriations hereafteracquired shall hereafter be made upon the express condition that the totalamount of water to be diverted at any one (1) time both under a primaryappropriation of water and a supplemental supply appropriation shall not be inexcess of one (1) cubic foot of water per second of time for each seventy (70)acre tract so irrigated, except that when the right to divert water under theprovisions of W.S. 41-4-317 through 41-4-324, is permitted the total amount ofsurplus water to be diverted at any one (1) time both under a primaryappropriation of water and a supplemental supply appropriation shall not be inexcess of one (1) cubic foot of water per second for each seventy (70) acretract so irrigated. Nothing herein shall be construed to apply to water storedunder a reservoir permit.
