037-1 Wyo. Code R. § 1-8
W.S. 41-3-305 provides that the holder or owner of an adjudicated water right to use the direct flow of a surface stream may store the water "so long as no other Wyoming appropriator or user is injured or affected thereby." A request to store a direct flow right must be made in writing to the State Engineer. Approval must be given by the State Board of Control before the direct flow may be diverted into storage under authority of this statute. Consideration of a request to store direct flow is generally a complex matter, which requires the availability of detailed information. Since no injury to other appropriators can occur, the storage is limited to the historic consumptive use, and is restricted to the same place of use. The details concerning the storage of direct flow rights are set out in the Regulations and Instructions of the State Engineer's Office.
