Section 690-507-0050 - Upper Umatilla River Subbasin

(A) Natural flows of the Upper Umatilla River and tributaries are classified for domestic, livestock, irrigation or noncommercial lawn and garden not to exceed 1/2 acre, municipal, industrial, power development (subject to the limitations of OAR Chapter 690, Division 51) mining (including sand and gravel mining), fish life, wildlife, recreation, pollution abatement, artificial groundwater recharge, and public instream uses during the period November 1 through May 31 each year. This classification rescinds the Commission's order of December 2, 1985, withdrawing the Umatilla River and tributaries from further appropriation from November 1 through May 31 each year until December 31, 1988;

(B) Until there is a final quantification of any reserved water rights of the Confederated Tribes of the Umatilla Indian Reservation, up to 75,000 acre feet of water in the Upper Umatilla River subbasin are classified for storage for the exclusive use of the Tribes. This classification applies to storage on or off the reservation in a single or multiple impoundments. Storage of this water is subject to the rights and priorities existing on June 24, 1988, and the withdrawal of the Umatilla River and tributaries from June 1 through October 31. All natural flow rights issued on the Umatilla River and its tributaries upstream from Pendleton and on the Umatilla main stem downstream from Pendleton after June 24, 1988, shall be subordinate to this classification. This classification shall be superior to the classification for storage contained in paragraph (C) of this subsection; and

(C) Subject to the rights and priorities existing on June 24, 1988, the withdrawal of the Umatilla River and tributaries from June 1 through October 31, and the 75,000 acre foot classification in paragraph (B) of this subsection, up to 100,000 acre feet of the annual yield of the Umatilla River above Pendleton are classified for all beneficial uses in conjunction with storage. All natural flow rights issued on the Umatilla River and its tributaries upstream from Pendleton and on the Umatilla main stem downstream from Pendleton after this date shall be subordinate to this classification, except that up to a total of 20,000 acre feet of additional permits may be granted for artificial groundwater recharge without subordination under this paragraph. Any storage project built under this classification shall include provisions for municipal, fish and wildlife, and recreation uses acceptable to the Commission.

(A) Recharged water used under a secondary permit for irrigation may only provide supplemental water to lands with existing irrigation rights or permits on June 24, 1988;

(B) Diversion of surface water for recharge for irrigation under a secondary permit shall not exceed 2.25 acre feet per acre to be irrigated; and

(C) If the recharged water is to be used for municipal or industrial purposes under a secondary permit, the applicant shall demonstrate to the satisfaction of the Commission that it has an active water conservation program.

(A) To support aquatic life in accordance with Section 3, Chapter 796, Oregon Laws 1983, no appropriation of water shall be made or granted by any state agency or public corporation of the state for waters of the Umatilla River and tributaries when flows are below the levels specified in Table 1. This limitation shall not apply to domestic and livestock use or to waters legally stored or released from storage; and

(B) To support aquatic life, no appropriations of water except for domestic and livestock uses or waters legally stored or released from storage shall be made or granted by any state agency or public corporation of the state when flows are below the specified levels for the streams listed in Table 1 with priority dates of 3-31-88.

(A) The groundwater resources of the Upper Umatilla River subbasin are classified for statutorily exempt groundwater uses (see definition), irrigation, municipal, industrial, power development, low temperature geothermal, mining, fish life, wildlife, recreation, pollution abatement, and artificial groundwater recharge; and

(B) Groundwater from the basalt reservoir in a five-mile radius around any municipal well of the cities of Adams and Pendleton is classified for municipal, group domestic and statutorily exempt groundwater uses (see definition) only. Other uses may be permitted if it is documented that a barrier to groundwater movement separates a proposed well from municipal wells and there will be no interference with municipal wells. Applications for other uses of groundwater within a five-mile radius of a municipal well shall automatically be referred to the Commission for review and consideration of public interest unless the affected city affirms that it is in favor of the proposed appropriation. This classification applies only when the affected city(ies) have a full-time conservation program in effect.
