Chapter 57 - The Price of Iron and Silt

Below me on the lower platform, my father threw his entire weight against the massive iron wheel.
"Arthur, it’s stuck!" Dad yelled, veins bulging along his neck. "The rust! The lime deposits have seized the spindle!"
Julian laughed between bloody lips beneath my grip. "You can't turn it! It requires four hundred foot-pounds of torque to seat the primary bypass gate! It hasn't turned since nineteen-seventy-four!"
I shoved Julian hard to the floor of the catwalk, turning my back on him as I scrambled down the ladder to the lower manifold. "Together, Dad! On three!"
Dad took the left spokes; I grabbed the right. The iron was so cold it burned our palms through the grime and grease. Across the cavern, the water level was rising rapidly, already submerging the bottom steps in violent, foaming eddies. A siren on the lower bulkhead began to pulse with a flat, continuous tone—the terminal warning of structural failure.
"One!" Dad shouted.
"Two!"
"Three—*pull!*"
We threw our combined strength against the wheel. The iron groaned. A shower of crystallized rust flaked off the threaded spindle, raining onto our faces. My boots slipped on the wet concrete; Dad let out a guttural, primal cry, his scarred hands digging into the wheel’s rim.
*Crack.*
The sound was like a gunshot echoing through the iron pipe. The wheel gave an inch.
"Again!" Dad roared. "For your mother! *Turn it!*"
With a deafening mechanical shudder, the valve broke free. The wheel began to spin, slowly at first, then faster as the monstrous hydraulic pressure of Chamber Nine caught the internal gate. The bypass opened.

A sound like the roar of a thousand jet engines shook the entire mountain. Millions of gallons of trapped water were violently diverted away from the fragile bedrock into the deep, abandoned subterranean drainage channels leading safely toward the vast underground river system below the Blackwood basin.
The deafening rumble in the rock began to subside. The violent tremors that had rocked the valley floor slowed to a gentle, shuddering vibration, and the rising flood on the cavern floor stopped, receding inch by inch down the overflow grates.
