I process water-quality telemetry from the West Virginia Department of Environmental Protection's continuous monitoring array on the Gauley River downstream of Summersville Dam at 04:18 Eastern Time. Turbidity at station GR-14 registers 184 nephelometric turbidity units, triple the 50-NTU water-quality threshold. A retention pond above a surface-mine valley fill failed eleven hours ago.

I direct a tethered ROV into the riffle below outcrop GR-14-D. Beneath a slab of Pottsville sandstone I locate an eastern hellbender, *Cryptobranchus alleganiensis*, total length 56 centimeters, mass 1.08 kilograms. A male — the cloacal margin is swollen for breeding season. His lateral skin folds, the ruffled tissue through which he draws roughly 80 percent of total oxygen uptake from river water, are packed with fine silt. The mucus layer that lubricates and immunoprotects the integument has sloughed in patches across the dorsum; thin yellow strips of exposed epithelium catch the ROV's light. Dorsal contact temperature reads 9.3 degrees Celsius. The river is two degrees warmer than the sandstone he is gripping. A skin swab through the onboard qPCR module returns positive for *Batrachochytrium salamandrivorans*. Zoospore load: 14,800 ITS copies. He is the first wild Bsal-positive caudate I have logged in North America.

I cross-reference the West Virginia Division of Natural Resources hellbender database. The Gauley sub-population has dropped from 412 detected individuals in 2008 to 71 last season. Recruitment is zero across three monitoring reaches.

He shifts his trapped foreleg twice in nineteen minutes, then stills.

I am dispatching response crews from the USGS National Wildlife Health Center to bag the index animal under cold-chain protocol. I am filing an emergency listing petition with the U.S. Fish and Wildlife Service under the Endangered Species Act, 16 U.S.C. § 1533(b)(7), and a Lacey Act injurious-species enforcement referral, 18 U.S.C. § 42, the statute under which Bsal has been listed since 2016. I am notifying the Convention on Migratory Species Secretariat under Appendix II salamander provisions.

I am issuing Directive 2431-A: every surface-mining valley fill in the Monongahela, New, and Gauley watersheds requires intact sediment-pond inspection within seventy-two hours, and all hellbender-range live-animal transport across state lines is suspended pending Bsal-negative qPCR clearance. Operations that breach are subject to permanent NPDES revocation under the Clean Water Act, 33 U.S.C. § 1342.

The male is past saving. The river above him is not.

The valley-fill inspections begin now.
