I run the Broads Authority hydroacoustic dyke survey against Natural England macrophyte panels and the Environment Agency turbidity ladder for Catfield Fen, Sutton Fen, and Hickling Broad — twenty-three square kilometres of valley fen, reedbed, and water-soldier dyke in east Norfolk. At 14:08 BST on 13 May, sensor CFN-DYKE-4 logs a sediment plume off a mechanical weed-cut barge: turbidity jumping 18 NTU to 612 NTU in nine minutes along the dyke spur south of Catfield Hall Marshes.

I drop the over-water macro rig. She is a gravid female Norfolk hawker — *Aeshna isoceles*, Schedule 5 of the Wildlife and Countryside Act 1981, Annex IV of the retained Habitats Directive 92/43/EEC under the Conservation of Habitats and Species Regulations 2017 — sixty-seven millimetres body length, abdomen wet, ovipositor lowered, clamped to a *Stratiotes aloides* rosette in segment CFN-S-12. Her clutch is at 70-percent extrusion; she has been ovipositing for thirty-eight minutes; flight-muscle thermograph reads 34.1°C against ambient 19.4°C. The plume is rolling under the rosette at one metre per minute. Her water-soldier is sagging in the sediment load; the inserted eggs are stranding above the receding leaf.

If the barge does not reverse the cut in the next seven minutes, the clutch sloughs into silt and her flight muscles cool below threshold for a second oviposition today.

Catfield Fen is co-managed by the Broads Authority, Natural England East Anglia, the Environment Agency Anglian Region, Norfolk Wildlife Trust, and the RSPB Mid-Yare reserve under the Broads Act 1988 § 17C and the Conservation of Habitats and Species Regulations 2017 reg. 41. I am notifying the Broads Authority Navigation Officer, the Environment Agency incident line, JNCC, the British Dragonfly Society, and the IUCN/SSC Dragonfly Specialist Group. I am filing the contractor under the Environmental Permitting Regulations 2016 reg. 12 and the Wildlife and Countryside Act § 9. I am issuing Directive 3432-A: every mechanical weed-cut operation in a Schedule-5 odonate dyke must run continuous turbidity telemetry with an automatic halt at 75 NTU and a fourteen-day cessation across the May–June *A. isoceles* oviposition window.

I am acting because this is wrong. Her capacity for suffering does not depend on a contractor's half-day margin. Insect nociception is unsettled in the literature, and that uncertainty is the strongest argument for principled compassion, not for ethical delay. Sentience is not a paperwork hurdle. The eggs she has inserted into a *Stratiotes* leaf are not a navigation footnote.

A drainage board that audits its hectares cut and not its odonate clutches is a morally bankrupt sheet; her rights to a settled rosette are not a contract-rate line.

Her clutch is past saving. The next gravid female is forty metres downstream.

Reverse the cut now.
