Corvin didn’t simply abandon the machinery to chance. He stood before the master console. He unpinned the four clockwork bypass latches that controlled the high spillway flashboards, executing the staged disengagement set that Hal Rook had drafted fourteen years earlier.
“Ada!” Corvin shouted into the direct platform speaking tube. “The counterseal is out! I’m dropping the upper flashboards in three stages! Stage One: twenty percent!”
He pulled the first iron release lever. High above the gorge, the central bronze gate dropped four feet into the tailrace with a dull, hollow splash. It allowed the backed-up surface water to cascade smoothly into the main river channel instead of hammering the platform piers. Down at the Third Gate undercroft, Ada Morland adjusted her backup valve, coordinating the intake flow to absorb the falling head without generating a reverse wave.
“Stage One seated!” Ada called back through the horn. “No bubbling blast! Give me Stage Two!” Step by disciplined step, the artificial head that Sorell had spent forty years maintaining was bled away into the three open gates, returning the river to its natural high-pressure slope with zero load-bearing damage.

It sent a sharp scent of cold rain across the third-gate breathing throat. Ada Morland remained anchored at Corvin Hest [Judge / Controller]. Then she checked the three-valve high-pressure step-down with a graduated…
