First Regular Session Sixty-fifth General Assembly STATE OF COLORADO INTRODUCED LLS NO. 05-0686.01 Thomas Morris HOUSE BILL 05-1185 HOUSE SPONSORSHIP Brophy, SENATE SPONSORSHIP (None), House Committees Senate Committees Agriculture, Livestock, & Natural Resources A BILL FOR AN ACT Concerning the authorization of the operation of temporary changes of water rights for up to five years. Bill Summary (Note: This summary applies to this bill as introduced and does not necessarily reflect any amendments that may be subsequently adopted.) Specifies that the 5-year duration limit for a substitute water supply plan that relates to a temporary change of use of water for which no adjudication application has been filed applies to the period during which such temporary change may operate rather than to the depletions associated with the change. Allows the approval of such temporary changes to mandate replacement of depletions beyond the 5-year period if necessary to protect senior water rights. Be it enacted by the General Assembly of the State of Colorado: SECTION 1. The introductory portion to 37-92-308 (5) (a), Colorado Revised Statutes, is amended, and the said 37-92-308 (5) (a) is further amended BY THE ADDITION OF A NEW SUBPARAGRAPH, to read: 37-92-308. Substitute water supply plans - special procedures for review - water adjudication cash fund - legislative declaration. (5) (a) Beginning January 1, 2002, for new water use plans involving out-of-priority diversions or a change of water right, if no application for approval of a plan for augmentation or a change of water right has been filed with a water court and, the water use plan or change proposed and in the case of a water use plan, the depletions associated with such water use plan or change will be for a limited duration not to exceed five years, or, in the case of temporary change in use, the changed use of the water will be for a limited duration not to exceed five years, the state engineer may approve such plan or change as a substitute water supply plan if the following conditions are met: (V) In addition to all other lawful uses, water rights for which a temporary change has been approved under this subsection (5) may be used in an augmentation plan decreed by the water court or in a substitute water supply plan approved pursuant to this section, in accordance with the governing augmentation plan, decree, or substitute water supply plan approval. An approval of a temporary change of water right shall include provisions for replacement of return flows in a manner sufficient to prevent injury to senior rights. Such provisions may require replacement of delayed return flows for a time period in excess of five years if necessary for the protection of senior rights. SECTION 2. Applicability. This act shall apply to approvals for substitute water supply plans occurring on or after the effective date of this act. SECTION 3. Safety clause. The general assembly hereby finds, determines, and declares that this act is necessary for the immediate preservation of the public peace, health, and safety.
