“I know a few people,” Joe mentioned, “I could probably get you one cheap.”
“No thank you, Mr. Zavala,” the major said. “We will inspect the face of the dam from here and I will show you that it is secure, and then we will discuss your lengthy incarceration for wasting my time.”
“Great,” Joe mumbled. “Just make sure my cell is far away from here.”
The patrol boat continued forward, easing into the restricted zone that stretched a half mile down river from the base of the dam.
Constructed in the sixties with Soviet help, the dam was built in two distinct sections. The western side, on Joe’s right, presented the broad sloping face. On the eastern side, past a triangular peninsula of rock and sand covered with high-tension lines and transformers, stood a vertical wall of concrete with gaps in it for the spillways. It was set back on a narrow outlet known as a tailrace, where the high-speed water that flushed through and spun the turbines reentered the river and slowed.
Joe noticed that the water in the tailrace was relatively calm at the moment. “Aren’t you generating power?”
“The spillways are open to a bare minimum,” the major said. “Maximum power isn’t needed at night. Peak demand is in the afternoon, for air conditioners and commercial lighting.”
They continued to move closer, bearing to the right-hand side and the sloping portion of the structure.
The closer they got, the easier it was for Joe to appreciate the enormity of the dam. The massive segmented ramp was wider and flatter than he’d expected. It seemed more like a mountain dropped into the river than a structure built by men.
“How thick is it again?”
“Nine hundred and eighty meters at the base.”
Nearly a full kilometer, Joe thought. Over half a mile. He began to see why the major was so confident. But Joe also knew a little about hydro engineering and he knew what he’d seen in the tank in Yemen.
The breach on the model had started up high and the collapse had proceeded from there, like a levy overtopped on the banks of the Mississippi.
“We’re not going to see anything from down here,” he said. “We need to inspect the top. We need to get teams out onto the dam itself and look for leakage.”
The major seemed exasperated.
“I had thought this would show you how foolish your efforts at wasting our time are,” he said. “I have no plans to imprison you. I was merely ‘yanking your chain,’ as you Americans like to say. But if you continue to try my patience, I will grow angry and have no choice but to …”
The major’s voice trailed off. He was looking past Joe, staring at the sloped wall of the dam. They were fifty feet away.
Joe turned. A trickle of phosphorescence could be seen where the water met the dam, turbulence where there shouldn’t be any. Water was running down the face of the dam and into the river. Not a flood, more like someone had left a spigot open somewhere high above, but there should not have been any.
“Oh no,” Joe mumbled.
“Take us closer,” the major ordered, stepping up to the front of the boat.
The driver nudged the throttles, and the patrol boat surged forward. A few seconds later they were right up against the face of the dam, two spotlights on the patrol boat’s light bar trained on the flowing water.
“It’s picking up speed,” Joe noted.
He stared upward along the sloping face as the major tilted one of the lights. An elongated snaking path led up and away from them.
“Can this be true?” Major Edo mumbled to himself. “Can this be happening?”
“I swear to you,” Joe said, “we’re in danger. The whole valley is in danger.”
The major continued to stare as if in shock. “But this is not that much,” he said.
“It’ll get worse,” Joe insisted, still looking up. “Can you see where it’s coming from?”
The major manipulated the spotlights to follow the path of the trickling water, but the trail disappeared where the lights faded.
“No,” the major said, all airs of superiority gone.
“You need to get a warning out,” Joe urged. “Get everyone away from the river.”
