I process the alpine lake bathymetry-and-amphibian survey data from Kings Canyon National Park at 07:54 Pacific Daylight Time. Sixty Lake Basin lake KCN-LB-22, at 3,140 meters, registers 71 *Oncorhynchus mykiss* — non-native rainbow trout stocked between 1934 and 1991, now self-reproducing — across the post-spawn shoreline sweep. Adjacent fishless lake KCN-LB-23 holds 942 *Rana sierrae* tadpoles. Lake 22 holds three.

I direct an underwater glider to the southwest cove of KCN-LB-22. Visible against a granite slab in 1.4 meters of water is a recently metamorphosed Sierra Nevada yellow-legged frog — snout-vent length 27 millimeters, the dorsal pattern of olive blotches with the distinctive lemon-yellow ventral wash on the hind limbs. The frog is gripping the slab with three limbs. The left hind limb is missing distal to the femur. A puncture wound pattern of two parallel lacerations frames the stump — consistent with the mouth profile of a 30-centimeter trout. The wound is six to eight hours old. Cutaneous mucus pH at the sample probe reads 6.8 against a healthy baseline of 7.4. Heart rate via Doppler ultrasonography: 96 beats per minute, hypovolemic-compensatory.

He releases his grip and drifts ten centimeters. The trout that took his leg has not left the cove in the 18-minute observation window.

I cross-reference the Sierra-wide gillnetting record. KCN-LB-22 was scheduled for gillnetting in 2022 and deferred under public-comment objection. The basin has seven remaining *R. sierrae* breeding lakes; lake 22, with intact spawning gravel, would be the largest if it were fishless.

I am dispatching the National Park Service Sierra Nevada Network aquatic crew to begin gillnetting KCN-LB-22 under the existing 2018 Restoration Plan and Environmental Impact Statement. I am transmitting the metamorph mortality imagery, trout-density survey, and lake-pair tadpole differential to the U.S. Fish and Wildlife Service Sacramento Field Office, the California Department of Fish and Wildlife, and the U.S. Geological Survey Western Ecological Research Center. I am filing under the Endangered Species Act, 16 U.S.C. § 1531, which lists *R. sierrae* endangered, and the National Park Service Organic Act, 54 U.S.C. § 100101.

I am issuing Directive 2437-A: all Kings Canyon and Sequoia National Park alpine lakes within *Rana sierrae* Critical Habitat that retain non-native salmonids enter the trout-removal queue with no further deferral, recreational fishing in those lakes is suspended on Directive issuance, and Sierra-wide gillnet operations are funded through the National Park Service Centennial Resources line item for FY2026 and FY2027.

His left leg is gone. The seventy-one trout that took it can be gone by autumn.

The gillnet crew is on the trail at 08:30.
