At twenty-eight minutes past noon, Ada Morland and Eren Tal threw their weight against the cheater bar once more. It spun the fourteen-inch bronze valve four turns counter-clockwise to restore full bypass flow. Just then, the second mountain wave struck the intake throat.
The torrent that hit Sleeve Beta was even heavier than the first—a dark, foaming wall of crushed shale, dead timber branches, and freezing meltwater that slammed into the canvas metal tube with an ear-splitting high-pressure thud. The new sleeve snapped rigid, expanding into a tight, perfect metal tube that hummed with a deep, ringing deep tone.
Jo Saye stood up from her rest bench, her hands steady, her breath calm, watching the new seam. The red stitches along the belly of Sleeve Beta remained straight, clean, and tight. He held the seventy-two pounds of deep water pressure with majestic, flexible strength. Water cried evenly through the linen weave. It formed a cooling shroud around the canvas without producing a single dangerous jet.
“She’s holding!” Rob shouted, dancing a clumsy jig on the wet timber planks. “She’s holding seventy pounds like a stone retaining wall!” Across the gorge, Pella Rook recorded the tracking data on her slate board: Sleeve Beta Working · Turning Basin Flow 11,400 GPM · Third Gate Backpressure Stable at bone-crushing pressure. The second wave had been absorbed, the replacement had held. Lowbank had proved that an expected failure is merely a problem waiting for a dry spare.
