Jack Mars - Situation Room

Kimball used a laser pointer to indicate the floodgates.

“If you look at the gates in relation to the building, you will see that they are quite large. Each one is ten meters tall, which means that six three-story-high jets of water were released all at once. The water pressure of Black Rock Lake sent the flood downstream at approximately twenty miles per hour, which doesn’t sound all that fast until you’re standing in front of it. Until this morning, the Black Rock Resort stood three miles south of the dam. The resort was made almost entirely of wood. The initial wall of water completely destroyed the resort, and as far as we know, the only survivors were a handful of people who left early to hike to the top of the dam, or to take drives on nearby scenic roads.”

“How many people were staying at the resort?” Luke said.

“There were two hundred and eighty-one guests listed in their online reservations system. Perhaps twenty of them either left the resort before the flood, or never arrived there for one reason or another. All of the others were swept away and are assumed dead. Combined with other disasters downstream, it will be several days before we have any kind of accurate body count.”

Luke got that odd familiar feeling. It returned like an old friend, one that you hadn’t seen in a while and were hoping not to see anymore. It came as a sickness in the pit of his stomach. It was death, the deaths of innocent people, minding their own business. Luke had dealt with it for far too long.

“Did anyone try to warn them?” he said.

Kimball nodded. “Workers in the dam’s control center called the resort on the phone as soon as they realized the floodgates were open, but apparently the flood had already reached there by the time they got in touch with anyone. Someone did pick up, but the conversation ended almost immediately.”

“Jesus. And what were the disasters downstream you mentioned?”

A map appeared on the screen. It showed the lake, the dam, the resort, and additional towns nearby. Kimball indicated a town. “The town of Sargent lies another sixteen miles south of the resort. It’s a town of twenty-three hundred people, and a gateway for visitors to the National Park. Most of Sargent is situated on a small hill, and the town received slightly more warning than the resort. They got enough warning, in fact, that the town emergency sirens sounded before the flood came. With an added sixteen miles to travel, the floodwaters hit with somewhat less force in Sargent, and many of the houses and buildings in town withstood the initial force of the flood and were not washed away. Many of the low-lying houses were, however, quickly inundated. More than four hundred people from Sargent are currently missing and presumed dead.”

Luke stared at the screen as Kimball’s laser pointer fell on the towns of Sapphire, Greenwood, and Kent, each one somewhat farther from the dam than the one before, and each one the site of a disaster in its own right. The scale of it was devastating, and although the floodgates were closed, the flood itself was going to continue traveling south and downhill for the next several days. Two dozen towns had been evacuated, but more fatalities were practically guaranteed. Some people in remote areas wouldn’t leave, or couldn’t.

“And you think hackers did this? How is that possible?”

Kimball glanced around the room. “Does everyone here have clearance to hear this next part? Can we please sweep anyone out who doesn’t have clearance?”

Low murmuring went around the room, but no one moved. “Okay, I’m going to assume that anyone here belongs here. If not, it’s your ass. Remember that.”

He turned back to Luke.

“The dam was built in 1943 to generate much-needed electricity during the war. It was built and is operated to this day by the Tennessee Valley Authority. For most of the dam’s life, the floodgates were operated by controls less sophisticated than your garage door opener. About twenty years ago, TVA started looking at ways to save money by automating their dams. Control centers in old hydroelectric dams are incredibly inefficient by modern standards. You’ve basically got people there around the clock, and their jobs include reading and writing logbooks, and opening and closing the spillways from time to time. The floodgates are almost never opened.

“TVA was thinking they could aggregate ten or twenty dam control centers into one centrally located control center. So they retro-fitted several dams with computer software that can be operated remotely. Black Rock was one of them. We’re talking about very simple software – yes means open the gates, no means close them. For one reason or another, they never did create the central control center, but they did make the software internet-based, in case they ever decided to do so. The final nail, so to speak, is that the science of encryption barely existed at that time, and the software has never been updated since it was first installed.”

Luke stared, stunned.

“You’re kidding.”

He shook his head.

“It was easy to hijack this system. It’s just that no one ever thought to do it before. What terrorist would even know this dam exists? It’s in a remote corner of a rural state. You don’t get a lot of style points for attacking Sargent, North Carolina. But as we’ve discovered, the results are as devastating as if they had attacked Chicago.”

Susan spoke for the first time during Kimball’s presentation. “And the worst thing about it is there are hundreds of dams like this across the United States. The truth is we don’t even know how many there are, and how many are vulnerable.”

“And why do we think the Chinese did it?” Luke said.

“Our own hackers at NSA traced the infiltration to a series of IP addresses in northern China. And we traced communication with those addresses to an internet account at a motel in Asheville, North Carolina, sixty miles east of the Black Rock Dam. The communications took place in the forty-eight hours before the attack. A SWAT team from the Bureau of Alcohol, Tobacco, and Firearms operates in that region, raiding unlicensed distilleries and breweries. That team was diverted to the motel, did a takedown of the room in question, and arrested a thirty-two-year-old Chinese national named Li Quiangguo.”

An image of a Chinese man being led from a small nondescript motel by a group of tall and broad ATF officers appeared on the screen. Another image appeared of the same man standing on a narrow roadway across from a lake. He stood in front of a historic plaque that read Black Rock Dam – 1943 , with a couple of paragraphs of description below.

“Although he has travel documents including a passport under this name, we don’t believe this is the man’s real name. As you know, the sequence of names in China is reversed – the surname comes first, followed by the given name. Li is one of the most common surnames in China, practically a generic name, similar to Smith in the United States. And Quiangguo, in Mandarin Chinese, means Strong Nation . This was a name with militaristic connotations that was very common after the Chinese Revolution, but fell into disfavor probably forty years ago. Further, Li was found with a handgun in his possession, as well as a small vial of cyanide pills. We believe he is a Chinese government agent, operating under an alias, who was supposed to kill himself if he was about to get caught.”

“So he got cold feet,” Luke said.

“Either that, or he just didn’t get to the pills in time.”

Luke shook his head. “After an operation like this one, an agent willing to kill himself would be holding the pill bottle in his hand, or have it in his pocket, twenty-four hours a day. What were the communications?”
