Or. Admin. Code § 690-077-0015

Current through Register Vol. 63, No. 12, December 1, 2024

Section 690-077-0015 - General Statements

(1) Instream water rights shall not take away or impair any permitted, certificated or decreed right to any waters or to the use of any rights vested prior to the date of the instream water right.

(2) The implementation of the instream water rights law is a means of achieving an equitable allocation of water between instream public uses and other water uses. When instream water rights are set at levels that exceed current unappropriated water available the water right not only protects remaining supplies from future appropriation but establishes a management objective for achieving the amounts of instream flows necessary to support the identified public uses.

(3) The amount of appropriation for out-of-stream purposes shall not be a factor in determining the amount of an instream water right.

(4) If natural streamflow or natural lake levels are the source for meeting instream water rights, the amount allowed during any identified time period for the water right shall not exceed the estimated average natural flow or level occurring from the drainage system, except where periodic flows that exceed the natural flow or level are significant for the applied public use. An example of such an exception would be high flow events that allow for fish passage or migration over obstacles.

(5) Unless the Director determines otherwise, for instream water rights established through instream transfers, leases, or allocations of conserved water, it is presumed that flows that exceed the estimated average natural flow or natural lake levels are significant for the applied public use, if the criteria in Subsection (5)(a) and (b), or in Subsection (5)(a) and (c) are met:

(a) The flow does not exceed the maximum amount of any instream water right application applied for under OAR 690-077-0020 for the same reach or portion thereof, and for the same public use.

(b) For the specified time period that flows are requested to exceed the estimated average natural flow or lake level, the stream is in an ODFW flow restoration priority watershed.

(c) The stream is listed as water quality limited and DEQ has provided scientific information that demonstrates that increased flows would improve water quality.

(6) If the source of water for an instream water right is other than natural flow such as storage releases or inter-basin transfer, the source shall be developed or a permit for development approved prior to or coincident in priority with the instream water right. The development of environmentally sound multipurpose storage projects that will provide instream water use along with other beneficial uses shall be supported.

(7) Instream water rights in rivers and streams shall, insofar as practical, be defined by reaches of the river rather than points on the river.

(8) When instream water rights are established through instream transfers, leases, or allocations of conserved water of existing water rights, the order, and, where appropriate, the certificate shall define the appropriate point, reach or reaches to which the new instream water right shall apply. Normally, a new instream water right shall be maintained downstream to the mouth of the affected stream; however, it may be maintained farther downstream if the amount of the instream water right is a measurable portion of the flow in the receiving stream or for a point or shorter distance if needed to account for return flow or to prevent injury.

(9) Instream water rights shall conform with state statutes and basin programs. All natural lakes and streams in the state shall be considered classified to allow all instream public uses unless specifically withdrawn from appropriation for such use.

(10) Instream water rights shall be approved only if the amount, timing and location serve a public use or uses.

(11) The combination of instream water rights, for the same reach or lake, shall not exceed the amount needed to provide increased public benefits and shall be consistent with Sections (4), (5), and (6) of this rule.

(12) An instream water right created through the conversion of a minimum perennial streamflow shall not take precedence over any rights having an earlier priority date, including storage rights except where an individual permit or water right specifies that it shall be subordinate to future uses or appropriations.

(13) An instream water right created through the conversion of a minimum perennial streamflow, which consists in whole or part of waters released from storage, is enforceable only as to the waters released to satisfy the instream water right.

(14) Instream water rights created through the conversion of minimum perennial streamflows shall carry with them any and all conditions, exceptions or exemptions attached to the minimum perennial streamflow, unless modified through hearing.
