The cold river spray from the Gray Rush drifted across the granite cutwater pier of the Third Gate like fine mist from an apothecary’s atomizer. Pella Rook knelt on the damp stone curb, her canvas apron tucked between her knees. She held her father’s brass measuring tongs over the edge of the open check well. Beside her, Senior Engineer Korr Var was adjusting the balance weight on a brass manometric float gauge, his glasses flecked with droplets of river water.
Far beneath their boots, inside the ancient underground throat where Davin Sorell’s extraction collars had choked the river for fourteen years, the water was moving with a deep, rhythmic, pulsing heave. It sounded like the breathing of a huge sleeping mammal. A slow, four-second surge upward as the river crest pushed into the throat. It was followed by a long, clean, sighing release as the water spilled smoothly through the clear bypass weir.
“Look at the float needle, Pella,” Korr Var said. He pointed his brass rule toward the dial. “Nine point two feet above mean. It hasn’t moved three-eighths of an inch in sixteen hours. The river rises an inch in the upper valley. Then, the throat opens naturally by four square feet to absorb the speed, then contracts as the head drops. Senn isn’t fighting the granite anymore. It’s breathing with the tide.”
