Those portions of the Kings River that connect with the San Joaquin River during high water years are also part of the experimental population area.

(3) Prohibitions. Except as expressly allowed in paragraph (b)(4) of this section, all prohibitions of section 9(a)(1) of the ESA (16 U.S.C. 1538(a)(1)), except 9(a)(1)(C), apply to fish that are part of the threatened, nonessential experimental population of CV spring-run Chinook salmon identified in paragraph (b)(2) of this section.

(4) Exceptions to the Application of Section 9 Take Prohibitions in the Experimental Population Area. The following forms of take in the experimental population area identified in paragraph (b)(2) of this section are not prohibited by this section:

(i) Any taking of CV spring-run Chinook salmon provided that it is unintentional, not due to negligent conduct, and incidental to, and not the purpose of, the carrying out of an otherwise lawful activity.

(ii) Any taking of CV spring-run Chinook salmon by an employee or designee of NMFS, the USFWS, other Federal resource management agencies, the California Department of Fish and Wildlife, or any other governmental entity if in the course of their duties it is necessary to: aid a sick, injured or stranded fish; dispose of a dead fish; or salvage a dead fish which may be useful for scientific study. Any agency acting under this provision must report to NMFS (see ADDRESSES section) the numbers of fish handled and their status on an annual basis.

(iii) Any taking of CV spring-run Chinook salmon for scientific research or enhancement purposes by a person or entity with a valid section ESA 10(a)(1)(A) permit issued by NMFS and a valid incidental take permit, consistency determination, or other take authorization issued by the CDFW.

(H) NMFS' approval of a research program shall be a written approval by the NMFS West Coast Regional Administrator.

(5) Limited Exception to the Application of Section 9(a)(1) Take Prohibitions Outside of the Experimental Population Area. The following forms of take are not prohibited:

(i) Any taking of CV spring-run Chinook salmon in those portions of the lower San Joaquin River and its tributaries, including the Merced River, downstream from its confluence with the Merced River to Mossdale County Park in San Joaquin County, that the avoidance of which would impose more than de minimus water supply reductions, additional storage releases, or bypass flows on unwilling persons or entities diverting or receiving water pursuant to applicable State and Federal laws.

(ii)(A) Any taking of CV spring-run Chinook salmon by the Central Valley Project (CVP) and State Water Project (SWP) that originates from reintroduction to the San Joaquin River that the avoidance of which would impose more than de minimus water supply reductions, additional storage releases, or bypass flows on unwilling persons or entities diverting or receiving water pursuant to applicable State and Federal laws.

(B) NMFS will prepare a technical memorandum that describes the methodology to ensure that CV spring-run Chinook salmon originating from reintroduction to the San Joaquin River do not cause more than de minimus water supply reductions, additional storage releases, or bypass flows associated with the operations of the CVP and SWP under any ESA section 7 biological opinion or section 10 permit that is in effect at the time for operations of the CVP and SWP. To the maximum extent feasible, NMFS will develop this technical memorandum in coordination with and with opportunity for comment by interested parties. The first technical memorandum will be completed before CV spring-run Chinook salmon will be released in the San Joaquin River. Prior to January 15 of each succeeding year, NMFS will update the technical memorandum and, if required by the methodology, determine the share of take at the CVP and SWP facilities that originates from the reintroduction to the San Joaquin River. This share of take of CV spring-run Chinook salmon reintroduced to the San Joaquin River will be deducted from or otherwise used to adjust the operational triggers and incidental take statements associated with any biological opinion that is in effect at the time for operations of the CVP and SWP facilities. NMFS will use best available commercial or scientific information to inform these calculations. The technical memorandum and annual determination will ensure that the reintroduction of CV spring-run Chinook salmon will not result in more than de minimus water supply reductions, additional storage releases or bypass flows of the CVP and SWP operations under any biological opinion or ESA section 10 permit that is in effect at the time for operations of the CVP and SWP on unwilling persons or entities diverting or receiving water pursuant to applicable State and Federal laws.

All other areas above Pit 7 Dam on the Pit River, McCloud Dam on the McCloud River, and Box Canyon Dam on the upper Sacramento River are not part of the NEP Area. The NEP Area extends up to the ridgelines to account for watershed processes and ends at the aforementioned dams because these dams lack fish passage facilities. The NEP Area is part of the species' historical range. The NEPs are all SR winter-run and CV spring-run Chinook salmon, including fish released or propagated, naturally or artificially, within the NEP Area.

(3) Prohibitions. Except as expressly allowed in paragraph (e)(4) of this section, all prohibitions of section 9(a)(1) of the ESA (16 U.S.C. 1538 (a)(1)) apply to fish that are part of the McCloud and Upper Sacramento Rivers Sacramento River winter-run and Central Valley spring-run Chinook salmon nonessential experimental populations identified in paragraph (e)(2) of this section.
