690-507-0030 Walla Walla River Subbasin (1) Objectives: In developing a program for the management, use and control of the surface and groundwater resources of the Walla Walla subbasin, the Commission has the following objectives: (a) Develop interstate cooperation with Washington in the management of surface and groundwater and related resources; (b) Protect instream values in selected streams by closing them to future appropriations or limiting new appropriations to selected nonirrigation uses; (c) Preserve the opportunity for future upstream storage for all beneficial uses; (d) Permit artificial groundwater recharge to offset declining groundwater levels and supplement existing groundwater uses; (e) Protect municipal groundwater supplies; (f) Prevent new appropriations from causing groundwater/ surface water interference. (2) Surface Water: Appropriation and use of surface water in the Walla Walla River subbasin shall comply with the following provisions: (a) The unappropriated waters of the Walla Walla River and tributaries from and including the Little Walla Walla Diversion to the state border are withdrawn from further appropriation. This withdrawal does not apply to domestic, livestock, fish and wildlife uses or water released from storage. Frost protection between March 1 and May 15, up to a cumulative total of 35 cfs of permits and rights with priority dates after December 2, 1985, is also exempt from this withdrawal. This withdrawal was established by the Commission on January 17, 1986; (b) The waters of Dugger Creek and tributaries, being entirely appropriated, are withdrawn from further appropriation. The purpose of the withdrawal is to avoid conflict between new uses and existing rights and administrative problems in the distribution of water resulting from new appropriations. The withdrawal was ordered by the State Engineer on August 12, 1933; (c) Classification: Permits to use surface water may be issued only for the following classified uses: (A) The surface waters of the Walla Walla River subbasin generally, are classified for domestic, livestock, irrigation, municipal, industrial, power development (subject to the limitations of OAR Chapter 690, Division 51), mining, fish life, wildlife, recreation, pollution abatement, artificial groundwater recharge, and public instream uses only; (B) The surface waters of the Walla Walla River and tributaries upstream from the Little Walla Walla diversion are classified for domestic, livestock, irrigation of noncommercial lawn and garden not to exceed 1/.2 acre, municipal, mining, fish life, wildlife, recreation, pollution abatement, artificial groundwater recharge and public instream uses only; (C) Subject to the rights and priorities existing on June 24, 1988, and established minimum perennial streamflows, 40,000 acre-feet of the annual yield of the Walla Walla River upstream from the Little Walla Walla diversion is further classified for all beneficial uses in conjunction with storage. All natural flow rights issued on the Walla Walla River and its tributaries upstream from the Little Walla Walla diversion after June 24, 1988, shall be subordinate to this classification. Any storage project built under this classification shall include provisions for municipal, fish and wildlife, and recreation uses acceptable to the Commission; (D) The surface waters of Mill Creek and tributaries are classified for domestic, livestock, irrigation of noncommercial lawn and garden not to exceed 1/2 acre, fish life, wildlife, pollution abatement, artificial groundwater recharge and public instream uses only. (E) The surface waters of Couse and Pine Creeks and tributaries are classified for domestic, livestock, irrigation of noncommercial lawn and garden not to exceed 1/2 acre, fish life, wildlife, pollution abatement, artificial groundwater recharge and public instream uses only. (d) Storage: Surface waters legally stored and legally released may be used for any beneficial purpose; (e) Artificial groundwater recharge: Use of surface water for groundwater recharge shall be subject to the following conditions: (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 3.375 acre feet per acre to be irrigated; (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; and (D) Water shall be recharged only between December 1 and May 15. (f) Minimum perennial streamflows: Minimum streamflows may be established to support aquatic life, minimize pollution or maintain recreation values: (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 Walla Walla 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. (3) Groundwater: The groundwater resources of the Walla Walla River subbasin are classified for statutorily exempt uses only as provided in and as consistent with ORS 537.545. (4) Basalt Well Flow Meter Installation and Groundwater Use Reporting: The Commission establishes a Serious Water Management Problem Area (SWMPA, ORS 540.435) as shown in Exhibit 507-1. (a) As used in 690-507-0030(4): (A) “Basalt well” is a water supply well that develops groundwater from the Columbia River Basalt Group within the designated SWMPA. (B) “Totalizing flow meter” is an instrument used to measure and display both the instantaneous flow rate of groundwater produced from the well and the total volume of groundwater produced from the well. (b) By no later than January 1, 2019, each water right holder, well owner, or well operator, shall properly install and thereafter properly maintain a totalizing flow meter on each basalt well within the SWMPA boundary listed as a point of appropriation on a valid water right. Totalizing flow meters must meet the specifications in subsections (e)–(h) and shall be properly installed according to manufacturer’s specifications. (c) Totalizing flow meters and the method of flow meter installation are subject to approval by Department Staff. Once installed, totalizing flow meters must be maintained in good working order. Department staff shall have access to the totalizing flow meters upon request. (d) The water right holder, well owner, or well operator shall keep a complete record of the volume of water appropriated each month, and shall submit a report which includes water use measurements to the Department on an annual basis by January 31 of each calendar year. The Director may request submission of reports more frequently as necessary to monitor and administer the SWMPA. Reports of water use measurements shall be submitted to the Department during the month of January for the preceding year, or more frequently as required by the Director. Reports shall be submitted on a form developed by the Department. (e) A totalizing flow meter shall meet the following specifications: (A) A totalizing flow meter shall have a rated accuracy of plus or minus 2 percent of actual flow for all flow rates for which the meter is expected to measure. (B) A totalizing flow meter shall register the full range of discharge from the well. (C) A totalizing flow meter shall have a visual and recording, mechanical or digital totalizer located on or adjacent to the flow meter, and shall be equipped with a sweep hand or digital readout so that instantaneous flow rate can be read. (f) The totalizing part of the flow meter shall have sufficient capacity to record the quantity of water authorized to be pumped over a period of 2 years. Units of water measurement shall be in acre-feet, cubic feet, or gallons and the totalizer shall read directly in one of these units. Flow meters recording in acre-feet shall, at a minimum, read to the nearest 1/10th acre foot, and the decimal multiplier shall be clearly indicated on the face of the register head. (g) Totalizers on each meter shall not be field reset without notice to and written permission from the Watermaster. (h) The totalizing flow meter shall be installed in accordance with all manufacturer specifications. There shall be no turnouts or diversions between the well and the flow meter. The flow meter shall be installed not less than five pipe diameters downstream from any valve, elbow, or other obstruction which might create turbulent flow, or other provisions shall be made that meet the manufacturer’s specifications to control or eliminate turbulent flow. (i) Failure to have and maintain a properly installed, functioning totalizing flow meter by January 1, 2019 will result in the Watermaster regulating and controlling an unmetered well such that no groundwater may be pumped or appropriated until a flow meter is obtained and installed consistent with these rules. (j) Consistent with ORS 536.900, Chapter 183, and OAR Chapter 690 division 260, the Department may assess civil penalties for violation of these rules.
