Chapter 5 - The Gathering Storm

By Monday morning, the temperature had done exactly what Maren’s computer models had predicted.
The mercury shot up from thirty-four degrees to fifty-eight degrees in less than twelve hours. A warm, humid wind blew in from the south, carrying with it a massive, dark bank of storm clouds that stretched from the Atlantic coast all the way to the Canadian border.
The sudden warm front began melting the dense, twenty-two-inch snowpack across the Green Mountain watershed at a terrifying rate. Millions of gallons of frozen water liquified into roaring surface runoff, pouring off the granite cliffs and rushing down into the narrow, winding channel of the Branch River.
I stood on the crest of the stone dam at 3:00 PM, wearing my heavy waterproof gear, holding an iron gauge rod.
The reservoir level was rising fast. In four hours, the water had elevated sixteen inches. The roaring white foam of the primary spillway was tumbling over the granite steps, echoing through the heavy forest like continuous thunder.
Maren walked up the stone abutment, carrying a ruggedized field tablet.
"Dad!" she called out over the roar of the water. "The USGS gauge three miles upstream just recorded a flow rate of two thousand two hundred cubic feet per second! The main rain front hasn't even hit us yet!"
"How is the lower valley holding up?" I asked, looking down the river channel toward Cascade Meadows.
"The HOA held an emergency meeting yesterday afternoon," Maren reported. "They officially ousted Heather Lynn, fired her Burlington lawyer, and voted unanimously to withdraw the lawsuit against us. Their new board president, Tom Miller, signed a formal waiver indemnifying us against all liability."
"That solves the legal problem," I said, looking at the dark sky above the ridge. "Now we have to solve the physical one."
"What do you mean?" Maren asked, looking at me.
"The snowmelt alone is manageable," I said, dipping my gauge rod into the upper crest. "Our reservoir has six feet of freeboard remaining. But if the Atlantic storm drops three inches of rain over the basin tonight, as forecasted..."
I pointed to the wooden emergency flashboards installed along the top of the stone wall—heavy three-inch-thick oak timbers held in place by steel pins, designed to temporarily raise the dam's holding capacity during extreme floods.
"The flashboards are old, Maren," I said. "They haven't been subjected to a 100-year flow event since the storm of 2011. If one of those oak boards breaks under the hydrostatic pressure, we lose two feet of retention capacity instantaneously."
"That would release a four-foot surge down the channel," Maren realized, her face turning serious. "Straight into the valley."
Before I could answer, my cell phone buzzed violently in my pocket. I pulled it out and answered.
"Arthur!" a frantic voice yelled over the speaker. It was Tom Miller, the newly elected president of the Cascade Meadows HOA.
"Tom, slow down," I said calmly. "What's going on?"
"Arthur, it's Heather!" Tom gasped, his voice laced with panic. "She's gone totally out of her mind! She took her husband's heavy track-loader from their construction staging yard! She drove it up the old logging road on the west side of the river!"
I froze. "What?"
"She thinks if she can manually break the timber flashboards on the west abutment," Tom yelled over the sound of wind in the background, "she can force the lake to drain now and prove she was right all along! She's out of her head, Arthur! She lost her house, her husband is in jail, and she's trying to destroy the dam before the storm hits!"
I didn't waste another second.
"Maren, get to the F-250!" I shouted, sprinting down the stone steps of the abutment. "Get the heavy tow cables, the iron wrecking bars, and my field medic kit!"
"Dad! The storm is hitting!" Maren yelled as the first massive drops of freezing rain began to pelt down from the black clouds above.
The sky opened up. A wall of rain slammed into the forest, turning the mountain path into a roaring torrent of yellow mud.
We jumped into the Ford F-250. I slammed the transmission into four-wheel-drive low, spun the tires through the thick mud, and roared up the narrow west logging trail, the heavy V8 engine screaming against the gradient.
The logging trail wound tightly along the steep cliff edge overlooking the roaring river sixty feet below. Through the blinding sheets of rain and flashing lightning, I saw it.
A massive, yellow fifty-ton CAT track-loader was idling at the far western edge of the dam abutment.
The heavy steel bucket of the loader was raised six feet in the air, positioned directly over the main timber flashboard structure that held back eleven million gallons of churning, brown water.
Inside the cab of the loader sat Heather Lynn.
Her hair was wild, her clothes disheveled, her face illuminated by the green glow of the dashboard lights. She was screaming unintelligibly into the storm, her hands gripping the hydraulic control levers.
"She's going to drop the bucket onto the flashboards!" Maren screamed from the passenger seat. "If that forty-ton hydraulic bucket impacts the oak timbers, it'll shatter the entire western retaining wall!"
"Stay in the truck!" I ordered.
I threw the truck door open, stepping out into the roaring gale. The wind whipped my rain coat around my legs as I sprinted toward the idling track-loader.
"Heather! Stop!" I roared over the sound of the thunder and the roaring river.
Heather snapped her head around inside the glass cab. When she saw me through the rain-streaked window, an expression of pure, unadulterated madness flashed across her face.
She pulled the hydraulic lever backward.
The massive steel bucket rose higher into the air, its sharp steel teeth glittering under the flash of lightning.
"I'm going to prove it!" she screamed through the glass, her voice distorted by the storm. "I'm going to break this wall! I'm going to show everyone what you did to me!"
May you like
She slammed the lever forward.
The forty-ton steel bucket dropped like a falling anvil toward the oak flashboards.
