Universal Citation: ID Admin Code 37.03.08.025

Current through August 31, 2023

01. Applications to Appropriate Unappropriated Water and Water Held in Trust. Applications to appropriate unappropriated water and water held in trust as provided by Section 42-203B(3), Idaho Code, will be evaluated using the criteria of Section 42-203A, Idaho Code, which requires an assessment to be made of the impact of the proposed use on water availability for existing water rights, the adequacy of the water supply for the proposed use, whether the application is filed for speculative purposes, the financial ability of the applicant to complete the project, and the effect of the proposed use on the local public interest. (3-18-22)

02. Applications to Appropriate Water from Sources Held by State in Trust. Applications to appropriate water from sources on which the state holds water in trust, pursuant to Section 203B(5), Idaho Code, will be processed in a three-step analysis. Evaluation will consider the purposes of "trust water" established in Section 42-203B, Idaho Code. (3-18-22)

a. First, the proposed use must be evaluated using the procedures and criteria of Section 42-203A, Idaho Code. If all criteria of Section 42-203A(5), Idaho Code, are satisfied, the application may be approved for unappropriated water. If the application does not satisfy the criteria of Section 42-203A(5) b, c, d, and e, Idaho Code, or is found to reduce the water to existing water rights other than those held in trust by the state, the application will be denied. If the application satisfies all criteria of Section 42-203A(5), Idaho Code, except Section 42-203A(5) a, Idaho Code, but is found to reduce water held in trust by the state, the application will be reviewed under criteria of Section 42-203C, Idaho Code. (3-18-22)

b. Second, Section 42-203C, Idaho Code, requires a determination of whether the proposed use will significantly reduce, individually or cumulatively with existing uses and other uses reasonably likely to exist within twelve months of the proposed use, the amount of trust water available to the holder of the water right used for power production that is defined by agreement pursuant to subsection (5) of Section 42-203B, Idaho Code (hereinafter termed "significant reduction"). If a significant reduction will not occur, the application may be approved without an evaluation of the public interest criteria of Section 42-203C(2), Idaho Code. (3-18-22)

c. Third, based upon a finding of significant reduction, the proposed use will be evaluated in terms of the public interest criteria of Section 42-203C(2), Idaho Code. (3-18-22)
