Each partner in a partnership ditch owned or used for a like purpose, shall have the right to carry, convey and transmit reservoir water, supplementing other water rights he may possess, through such partnership ditch, to the full extent of the carrying capacity represented by his interest, as a partner, in such ditch, but no greater. Every such person carrying, conveying and transmitting water through such ditch, or having the same done for his benefit, shall pay all expenses incurred by reason of all extra labor in cleaning such ditch, change of division boxes, and other additional expenses made necessary by reason of carrying such reservoir water through any such ditch. The right herein granted to any person, shall also extend to the owner, manager or lessee of a reservoir, who desires to use any such ditch to carry, convey or transmit water through such ditch for the benefit of any such person to whom the right herein mentioned has been granted as aforesaid.

41-3-320. Owners of ditches and reservoirs; sale or lease of impounded water.

Except as otherwise provided by deed or other written instruments of the owner or owners of the right to impound water in any reservoir, such reservoir owner or owners shall, after the completion of the works in connection with such reservoir, be held to be the owner of the right to impound the water, and the right to sell or lease a portion or all his right to the impounded waters; provided, that the sale of any portion of the capacity of any reservoir shall carry with it an interest in the reservoir and works appurtenant thereto of such proportion as the portion sold bears to the total capacity of the reservoir; and provided, further, that the water stored in any reservoir cannot be used outside the boundaries of the state of Wyoming without special permit from the state engineer; and provided, further, that the state engineer may deny any use of water from any reservoir that would be detrimental to the public interest.

41-3-321. Owners of ditches and reservoirs; priority of right to store or impound.

The priority of right to store or impound water under this act shall date from the filing of the application in the state engineer's office.

41-3-322. Owner's report of persons entitled to use water; superintendent's report of use of water.

The owner of each reservoir shall annually, in writing, before or during the irrigating season and before the releasing of the water from the reservoir, deliver to the water commissioner having jurisdiction over such reservoir a list or lists of parties entitled to use water from such reservoir during the irrigating season of such year, and also a list as near as may be of the lands proposed to be irrigated, and shall immediately notify such water commissioner of any changes in such list or lists. The superintendent of the water division in which such reservoir is situated shall annually on or before the first day of December in each year make a written report to the state engineer of the state, enumerating in detail the person or persons who during the irrigating season immediately preceding use any part of such reservoir water, and shall also enumerate therein the lands upon or uses for which said water was applied during such irrigating season so that the state engineer may be kept at all times advised as to whether or not such water has been applied to beneficial uses.

41-3-323. Deeds for water rights; attaching of rights to land; sale, lease, transfer or use.

The reservoir water and rights acquired under reservoir permits and adjudications shall not attach to any particular lands except by deed, or other sufficient instrument conveying such water or water rights, executed by the owner or owners of such reservoir, and such water and water rights, except when attached to particular lands as aforesaid, may be sold, leased, transferred and used in such manner and upon such lands as the owner of such rights or partial rights may desire, provided, that such water must be used for beneficial purposes.

41-3-324. Deeds and leases for water rights; execution and recording.

All deeds for reservoir water and water rights and all leases of the same for periods of three (3) years or more shall be executed and acknowledged as deeds are executed, and shall be recorded in the office of the county clerk of the county in which the reservoir is situated and also filed in the office of the state engineer. All leases of such water and water rights for a period less than three (3) years shall be in writing and filed in the office of the state engineer.

41-3-325. Excess stored water to be furnished applicants; preferences; rates.

The owner or owners of a reservoir impounding a greater quantity of water than the owner or owners thereof necessarily use for irrigation and other beneficial purposes in connection with their own lands shall, when application is made to them for that purpose, furnish such surplus water at reasonable rates to the owners of lands lying under and capable of being irrigated from such reservoir for the purpose of irrigating and rendering the same productive, and maintaining their productiveness, and in case of refusal so to do, the owner or owners of such reservoir may be compelled by proper proceedings to furnish such water on such reasonable terms as to the court may seem meet and proper. The water user who may have used any water from such reservoir for any particular year shall have the preference as to the use of the same water for the next ensuing year. The state engineer, the water commissioner of the particular district and the water superintendent having jurisdiction over the region of any reservoir, shall together constitute a board of special commissioners, and shall have power, when application is made to them by either party interested, to establish reasonable maximum rates to be charged for the use of water from any reservoir, whether furnished by individuals or a corporation. The establishment of such rate shall be made only after notice given and public hearing had, at which hearing the applicants may produce witnesses and evidence, and such witnesses must be sworn and may be cross-examined. No commissioner shall sit upon such board and determine such rate who is employed by one (1) of the applicants or if the relationship of debtor or creditor exists between him and one (1) of the applicants. Nothing contained in this section shall be construed to deny the right to store water for use for more than one (1) year.

41-3-326. Applicability of ownership provisions.

The provisions of this act shall apply to reservoirs heretofore lawfully constructed as well as to all reservoirs hereafter lawfully constructed.

41-3-327. Carey Act lands.

All acts and parts of acts in conflict herewith, excepting such as relate to Carey Act lands, are hereby repealed.

41-3-328. Witnesses' fees and mileage.

Every witness who shall attend before the court, or the judge thereof in vacation, or before the person appointed to take testimony in causes relating to water rights, under subpoena, by request of any party, shall be entitled to the same fees and mileage as witnesses in civil cases in the district court, and shall be paid by the party requiring the testimony.  41-3-329. Change in point of diversion.

(a) The storage of water by means of a reservoir is a diversion, and the point of diversion is the point defined in the permit where the longitudinal axis of the dam crosses the center of the streambed.

(b) A change in point of diversion of a reservoir may be granted pursuant to W.S. 41-3-114 by the state engineer if the water right is unadjudicated, or by the state board of control if the water right has been adjudicated. No petition shall be granted if the rights of other appropriators shall be injuriously affected thereby or if the change is not within the original project concept. In deciding whether to grant or deny a proposed change in point of diversion of a reservoir within the original project concept, the state engineer or the board of control shall consider:

(i) The distance between the old point of diversion and the new point of diversion;

(ii) The water administration problems which may be created by granting the change in the point of diversion;

(iii) The effect of the petition upon Wyoming's entitlement to water under compacts, court decrees and treaties;

(iv) The rights of other appropriators; and

(v) The safety aspects of the new point of diversion.

ARTICLE 4 - ABANDONMENT OF WATER RIGHTS

41-3-401. Failure to use water; extension of time; initiation by benefitted or injured user; hearing; appeal.

(a) Where the holder of an appropriation of water from a surface, underground or reservoir water source fails, either intentionally or unintentionally, to use the water therefrom for the beneficial purposes for which it was appropriated, whether under an adjudicated or unadjudicated right, during any five (5) successive years, he is considered as having abandoned the water right and shall forfeit all water rights and privileges appurtenant thereto. Notwithstanding any provision in this section to the contrary, the holder of an appropriation for the diversion and storage of water in a reservoir, from which water or a portion thereof has not yet been beneficially used for the purposes for which appropriated, or the owner of a lawful dam or diversion system as defined in W.S. 41-3-307 under which appropriated water becomes unused due to necessary repairs or replacement, may apply to the board of control for an extension of time not to exceed five (5) years, within which to use water or reactivate use of water therefrom for the beneficial purposes for which it was appropriated. In the application the holder shall demonstrate the exercise of due diligence toward the utilization of the appropriation, and that notwithstanding the exercise of due diligence, reasonable cause exists for nonuse. Reasonable cause includes but is not limited to delay due to court or administrative proceedings, time required in planning, developing, financing and constructing projects for the application of stored water to beneficial use which require in excess of five (5) years to complete, delay due to requirement of state and federal statutes and rules and regulations thereunder and any other causes beyond the control of the holder of the appropriation. Upon receipt of an application for extension, the board of control shall proceed under the provisions of W.S. 16-3-101 through 16-3-115 and may grant an extension of time as it finds proper, not to exceed five (5) years, for the application of the appropriated water to the beneficial use for which it was appropriated. A prior grant of extension of time hereunder does not preclude the holder from applying for additional extensions of time, each not to exceed five (5) years, upon similar application and showing. The granting of an extension of time precludes the commencement of an abandonment action against the appropriation during the period of extension.

(b) When any water user who might be benefitted by a declaration of abandonment of existing water rights or who might be injured by the reactivation of the water right, desires to bring about a legal declaration of abandonment, he shall present his case in writing to the state board of control. The board has exclusive original jurisdiction in water right abandonment proceedings. The board shall, if the facts so justify, refer the matter to the superintendent of the water division where the abandonment is claimed to have occurred for public hearing. The total absence of water to divert during an irrigation season precludes the inclusion of any such period of nonuse resulting therefrom in the computation of the successive five (5) year period under this section. The following persons have standing to petition the state board of control to declare the abandonment of existing water rights under this section:  (i) Any person who has a valid adjudicated water right or is the holder of a valid permit from the same source of supply which is equal to or junior in date of priority to the right for which abandonment is sought; or

(ii) The holder of a valid water right entitled to surplus water under W.S. 41-4-318 through 41-4-324, petitioning to abandon a water right from the same source of supply if the right sought to be abandoned has a priority date of March 1, 1945, or earlier.

(c) The superintendent shall notify the holders of water rights sought to be abandoned by certified mail that a hearing will be held. The hearing shall be conducted pursuant to all applicable provisions of the Wyoming Administrative Procedure Act. All notices shall advise interested parties of the time, place and purpose of the hearing. Parties initiating abandonment actions are designated as contestants. Water right holders or other persons with interests in the rights allegedly abandoned are designated as contestees. In any case where notice by certified mail cannot be accomplished an advertisement published once a week for three (3) consecutive weeks in a newspaper of general circulation in the county in which the abandonment is alleged to have occurred, naming the parties in the case and setting forth the time, place and purpose of the hearing is sufficient. Cost of advertising shall be paid by the contestant.

(d) A transcript shall be made of the hearing and delivered to the superintendent. The contestant shall provide and pay for the costs of the record. At the conclusion of the hearing the transcript, all other evidence and the report of the superintendent shall be transmitted to the board by the superintendent. At its next meeting the board shall vote to declare the right in question abandoned, either wholly or partially, or to decline to do so.

(e) The board shall enter an order reflecting its action on the abandonment hearing, and shall, within sixty (60) days, send a certified copy of the declaration to each contestant and contestee. Appeals may be taken as provided by law.

(f) An appropriation for irrigation use is not subject to partial abandonment for failure of the appropriator to irrigate part of the lands described in his permit or certificate of appropriation during the successive five (5) year period if:  (i) Facilities to divert the water and to apply it to beneficial use upon the lands which were not irrigated existed in usable form during the period of nonuse; and

(ii) There was not a sufficient supply of water available, because of regulation for prior water rights or because shortage of supply resulted in insufficient water to satisfy the appropriation in full, to irrigate the lands for which abandonment is sought provided that a diligent effort was made to use the supply which was available.

41-3-402. Initiation by state engineer; hearing; appeal.

(a) When any appropriator has failed, intentionally or unintentionally, to use any portion of surface, underground or reservoir water appropriated by him, whether under an adjudicated or unadjudicated right, for a period of five (5) successive years, the state engineer may initiate forfeiture proceedings against the appropriator with the state board of control, to determine the validity of the unused right. The state engineer shall designate the area to be affected by the proceedings, not to contain in area more than one (1) water division. The total absence of water to divert during an irrigation season precludes the inclusion of any period of nonuse resulting therefrom in the computation of the successive five (5) year period. The secretary of the board shall refer the matter for a hearing to the superintendent of the water division where the forfeiture is alleged to have occurred. This section does not apply to any reservoir, lawful dam or diversion system for which an extension has been granted during the period of extension under W.S. 41-3-401(a).

(b) The superintendent shall send notices, by certified mail, of the time, place, and purpose of the hearing to all owners of lands covered by the appropriations involved in the forfeiture proceeding. Such persons shall be joined as parties to the forfeiture proceedings as contestees. The state shall be designated as contestant. In a case where notice by certified mail cannot be accomplished, an advertisement published once a week for three (3) consecutive weeks in a newspaper of general circulation in the county in which the forfeiture is alleged to have occurred, naming the parties in the case and setting forth the time, place, and purpose of the hearing, and a general description of the water rights whose status is under consideration, shall answer the requirements of notice. Notice by certified mail shall first be attempted before notice by advertisement is employed. Advertisement costs shall be paid by the state engineer. In addition, whenever it appears necessary for full and proper notice, the superintendent may post a notice of the hearing in a conspicuous place on the land or at the place where the water rights are attached or utilized, or on the point of diversion.

(c) Any use of a contested water right, easement, privilege, or portion thereof, by the water user, his lessees, agents, transferees or assignees on or after the date of the notice shall be inadmissible as evidence of beneficial use in all hearings or appeals arising out of the alleged forfeiture.

(d) A transcript shall be made of the hearing. The record shall be delivered to the superintendent. The state engineer shall provide and pay for the costs of such record. At the conclusion of the hearing, the transcript, all other evidence, and the report of the superintendent shall be transmitted to the board of control by the superintendent. At its next meeting, the board shall vote by secret written ballot to declare the right in question forfeited or to decline to do so. Any forfeiture requires three (3) affirmative votes by the board.

(e) Whenever the state engineer has initiated forfeiture proceedings, he shall not participate as a voting member of the board of control in any determination of whether any water right, easement, or privilege is to be forfeited, all other laws to the contrary notwithstanding.

(f) Such proceedings shall not be initiated by the state engineer after the use of a water right, easement or privilege has occurred.

(g) Any time within two (2) years after the date the board has entered an order forfeiting a water right, any person who can demonstrate to the satisfaction of the board by written petition, proof, or affidavits, that he was an owner, lessee or beneficiary of the forfeited right, that he had no actual or constructive notice of the forfeiture hearings, and that he has been damaged thereby, may require the board to reopen the case for a determination of whether such right shall remain forfeited or be reactivated without loss of priority.

(h) Whenever the board has declared any water right forfeited, it shall send a certified copy of the declaration to each contestee within sixty (60) days. Such party may within thirty (30) days after the date of mailing, appeal to the district court of the district wherein the hearing was originally held or in the district court of Laramie county.

(j) Nothing in this section shall be construed to allow the state engineer to initiate forfeiture proceedings against water rights which are being put to beneficial use, wholly or in part.

ARTICLE 5 - WATER DIVISIONS AND SUPERINTENDENTS

41-3-501. Water divisions defined.

(a) The state of Wyoming is hereby divided into four (4) water divisions, as follows:

The governor may remove any superintendent as provided in W.S. 9-1-202. The state engineer shall from time to time conduct examinations for candidates for the position of division superintendents, and a list of those who qualify shall be filed with the governor and the governor, from that list, shall appoint division superintendents for the various divisions as vacancies occur. No candidate is eligible for appointment as division superintendent unless he is qualified by training and experience. The examination shall consist of questions relative to the irrigation laws and their administration, the measurement of flowing water, evaporation, seepage, drainage and the hydrographic features of the water division in which the candidate seeks appointment.

41-3-503. Superintendents; duties generally.

Said division superintendent shall have general control over the water commissioners of the several districts within his division. He shall, under the general supervision of the state engineer, execute the laws relative to the distribution of water in accordance with the rights of priority of appropriation, and perform such other functions as may be assigned to him by the state engineer. It shall be the duty of said division superintendent to regulate and control the storage and use of water under all rights of appropriation which have been adjudicated by the board of control or by the courts, and to regulate and control the storage and use of water under all permits approved by the state engineer, whether the rights acquired thereunder have been adjudicated or not.

The state engineer shall, after due notice, hear whatever testimony may be brought forward by the petitioner, either orally or by affidavit and, through the division superintendent, shall have power to suspend, amend or confirm the order complained of.

ARTICLE 6 - WATER DISTRICTS AND COMMISSIONERS

41-3-601. Division of state into districts.

The board of control shall divide the state into water districts, said water districts to be so constituted as to secure the best protection to the claimants for water and the most economical supervision on the part of the state; in laying out such districts each stream system of practicable administrative scope shall be included within a single district.

41-3-602. Commissioners; appointment; term; removal; filling of vacancies; hydrographers.  (a) The governor shall appoint a water commissioner for each water district, if needed, who shall be selected from persons recommended by the superintendent of the water division in which the water district is situated with the advice of the board of county commissioners of the county or counties, lying wholly or partly within the water district. The water commissioner shall be an employee of the state engineer. Each commissioner shall hold his office until his successor is appointed and shall have qualified, and the governor shall, by like selection and appointment, fill all vacancies which shall occur in the office of water commissioners, and may, at any time, remove any water commissioner as provided in W.S. 9-1-202.

(b) The governor may appoint a water commissioner to more than one (1) district on recommendation of the division superintendent and the county commissioners of the interested county or counties.

41-3-603. Commissioners; general powers and duties; appeals from decisions.

(a) The water commissioner shall, as near as may be practicable, divide, regulate and control the use of the water of all streams, springs, lakes or other sources of water within his district as will prevent the waste of water or its use in excess of the volume to which the appropriator is lawfully entitled. The water commissioner has the authority to require the filling of any reservoir whenever practical and whenever water is available for storage from the stream from which the appropriation is established.

(b) Any person who may be injured by the action or inaction of the water commissioner has the right to appeal to the division superintendent and, from his decision, the person aggrieved may appeal to the state engineer. From the decision of the state engineer, an appeal may be taken to the district court of the county where the ditch or ditches, reservoir, well or wells over which the controversy arises are situated.  41-3-604. Commissioners; additional powers and duties; defense by county attorney.

It shall be the duty of the said water commissioner to divide the water of the natural stream or streams of his district among the several ditches and reservoirs taking water therefrom, according to the prior right of each, respectively, in whole or in part, and to shut and fasten, or cause to be shut and fastened, the headgates of ditches and shall regulate or cause to be regulated the controlling works of reservoirs, in times of scarcity of water, as may be necessary by reason of the priorities of right existing from said streams of his district. Such water commissioner shall have authority to regulate the distribution of water among the various users under any partnership or incorporated ditch or any ditch owned by joint owners not incorporated and not in a partnership, or partnership or incorporated reservoir or reservoir owned by joint owners not incorporated or not included in a partnership, where rights have been adjudicated, in accordance with existing decrees. Whenever, in the pursuance of his duties, the water commissioner regulates a headgate to a ditch or the controlling works of reservoirs, it shall be his duty to attach to such headgate or controlling works a written notice, properly dated and signed, setting forth the fact that such headgate or controlling works has been properly regulated and is wholly under his control and such notice shall be a legal notice to all parties interested in the division and distribution of the water of such ditch or reservoir. It shall be the duty of the county attorney to appear and defend the division superintendent or any water commissioner who shall be made a defendant in any case which may arise in the pursuance of the official duties of any such officer within the county of such county attorney.

41-3-608. Commissioners; reports.

(a) All water commissioners, when on duty, shall make reports whenever called upon to do so, by the division superintendent of their division. Said reports shall contain the following information:

(i) The amount of water actually coming into the district to supply ditches, canals and reservoirs;

(ii) Whether such supply is on the increase or decrease;

(iii) What ditches, canals and reservoirs are at that time without their proper supply; and

(iv) Such other and further information as the division superintendent of that division may require.

41-3-609. Commissioners; disqualification for personal interest or prejudice.

Whenever an affidavit is filed with the state engineer by a water user stating that the water commissioner of a district has a personal interest or prejudice in the use of water from a stream and that the person making the affidavit believes that because of the commissioner's interest or prejudice he cannot obtain a fair and just division of water, the state engineer may designate a water commissioner from another district as substitute commissioner.

41-3-610. Commissioners; authority and duties of substitute.

The term of service of assistant commissioners may be terminated at any time by the water commissioner or the division superintendent, and shall in no event continue after the emergency has ceased to exist.

41-3-612. Rotation among water users; approval of commissioner.

(a) To bring about a more economical use of the available water supply, it is lawful for water users owning lands to which are attached water rights, to rotate in the use of supply to which they may be collectively entitled, or a single water user, having lands to which water rights of a different priority attach, may in like manner rotate in use, provided that all water rights subject to rotation are in priority. Rotation of water will be allowed only if it can be accomplished without injury to other appropriators.

(b) Prior to the commencement of any rotation in the use of water pursuant to this section, the owner or owners of the water rights to be rotated shall file a notice of intention to rotate with the appropriate water commissioner, on the form provided for that purpose by the commissioner, and shall obtain the water commissioner's written approval which shall be endorsed on the form.  (c) Performance of the rotation shall be enforced by the water commissioner in accordance with the terms and conditions included in the form signed and approved by the water commissioner. The state engineer may adopt such rules and regulations as are necessary for him to efficiently administer this section.

41-3-613. Headgates, flumes or measuring devices; owners to construct and maintain; failure to comply.

The owner or owners of any ditch or canal shall maintain, to the satisfaction of the division superintendent of the division in which the irrigation works are located, a substantial headgate at the point where the water is diverted, which shall be of such construction that it can be locked and kept closed by the water commissioner; and such owners shall construct and maintain, when required by the division superintendent, flumes or other measuring devices at such points along such ditch as may be necessary for the purpose of assisting the water commissioner in determining the amount of water that is to be diverted into said ditch from the stream, or taken from it by the various users. Any and every owner or manager of a reservoir, located across or upon the bed of a natural stream, shall be required to construct and maintain, when required by the division superintendent, a flume or measuring device of a plan to be approved by the state engineer, below such reservoir at a point not to exceed six hundred (600) feet distant therefrom, and a flume or measuring device above such reservoir or each and every stream or source of supply discharging into such reservoir, for the purpose of assisting the water commissioner or superintendent in determining the amount of water to which prior appropriators are entitled and thereafter diverting it for such prior appropriators' use. When it may be necessary, for the protection of other water users, the division superintendent has authority to require flumes to be installed along the line of any ditch. If any such owner or owners of irrigation works shall refuse or neglect to construct and put in such headgates, flumes or measuring devices after ten (10) days notice to do so by division superintendent, it shall be the duty of the water commissioner of the district in which such headgate is located, on order of the division superintendent, to close such ditch to the passage of water, and the same shall not be opened or any water diverted from the source of supply, under the penalties prescribed by W.S. 41-3-614, until the requirements of the division superintendent as to such headgate, flumes or measuring device have been complied with, and if any owner, or manager of a reservoir located across the bed of a natural stream shall neglect or refuse to put in such measuring device after ten (10) days notice to do so by the division superintendent, the water commissioner shall open the sluice gate or outlet of such reservoir and the same shall not be closed under penalties pursuant to W.S. 41-3-614, until the requirements of the division superintendent as to such measuring devices are complied with.

41-3-614. Well, headgate or waterbox; prohibited acts; penalty for violation.

It shall be unlawful for any person to willfully use or possess water which has been lawfully denied by the water commissioner or other competent authority or to open, close, change or interfere with any well, pump, reservoir outlet valve, dam, diversion, headgate or waterbox without authority. Any violation of this section shall be punishable pursuant to W.S.
