41-3-1006. Appropriation of unappropriated waters for direct instream flows.

(a) Any application for a permit to appropriate direct flow waters for the purpose of providing instream flows shall be by stream segment, as defined in W.S. 41-3-1002.

(b) If the water development commission, under W.S. 41-3-1004, determines that storage of water for the purpose of providing instream flows is not feasible but that appropriation of direct flow water appears feasible, the state engineer shall act on applications for permits to appropriate water filed under W.S. 41-3-1003(c) in the name of the state of Wyoming.

(c) Subsequent to submission of an application for an instream flow appropriation, the game and fish commission shall conduct relevant studies on the proposal.

(d) The applicant for an instream flow water right shall publish a notice of the application and hearing in a newspaper of general circulation in the area near the proposed reservoir site or stream segment, once each week for at least two (2) consecutive weeks prior to the hearing provided by subsection (e) of this section which notice shall briefly describe the application.

(e) Prior to granting or denying the application, the state engineer shall conduct any studies as are deemed necessary to evaluate the proposed instream flow and the necessary amount of water to maintain existing fisheries and shall hold a public hearing. At the public hearing, the game and fish commission shall present its studies and any other interested parties shall present views on the proposed instream flow appropriation. The state engineer may place a condition on the permit, if one is granted, requiring a review of the continuation of the permit as an instream flow appropriation.

(f) If an application for an instream flow appropriation is approved by the state engineer, it shall be deemed that work has been commenced and completed and beneficial use made thirty (30) days after the date of approval for purposes of W.S. 41-4-506 and proof of appropriation shall not be submitted until three (3) years thereafter.

(g) The state engineer shall not issue an instream flow permit where the instream flow right would be included as a portion of the consumptive share of water allocated to the state of Wyoming under any interstate compact or United States supreme court decree.

(h) The amount of water appropriated for instream flow in each river basin in Wyoming shall not result in more water leaving the state than the amount of water that is allocated by interstate compact or United States supreme court decree for downstream uses outside of Wyoming.
