Current through Register Vol. 63, No. 6, June 1, 2024

Section 340-041-0140 - Basin-Specific Criteria (Goose and Summer Lakes): Beneficial Uses to be Protected in Goose and Summer Lake Basins

[Note: The amended beneficial uses designated in this rule, adopted by the Environmental Quality Commission on November 16, 2023, are not applicable for Clean Water Act purposes until approved by the U.S. EPA. For applicable uses prior to EPA approval see "Beneficial Uses of Oregon's Waters" on DEQ's Water Quality Standards website (https://www.oregon.gov/deq/wq/Pages/WQ-Standards-Uses.aspx).]

(1) Water quality in the Goose and Summer Lake Basins (see Figure 1) must be managed to protect the designated beneficial uses shown in Table 140A (November 2003).

(2) Designated fish uses to be protected in the Goose and Summer Lake Basins are shown in Figure 140A, 140B, and 140C (October 2023).

(3) For purpose of protecting active resident trout spawning areas, as required by OAR 340-041-0016 (1):

(a) The dissolved oxygen spawning criteria will apply to the salmonid spawning locations and times shown on OAR 340-041-0140: Figure 140C.

(b) In addition to the salmonid spawning areas shown on shown on Figure 140C, DEQ will determine where additional active spawning areas used by resident trout occur as data becomes available. DEQ will identify additional spawning habitat and areas determined to be active resident trout spawning areas in a publicly available inventory. The determinations recorded in the inventory will be incorporated into the designated use tables and maps in OAR 340-041 periodically through rulemaking. When resident trout spawning is determined to be an existing use based on the best available data and is added to the resident trout spawning inventory, DEQ will apply the spawning criteria for dissolved oxygen to protect the existing trout spawning use.
