Ten Nashville, Term., area dams in the Cumberland River basin prevented an estimated $1.8 billion in flood damages in March flooding. Nashville received 7.01 inches of rain March 27-28, making it the second highest two-day total since records began in 1871, according to the Nashville Engineer District's public affairs team. The Cumberland River reached 40.55 feet in Nashville, exceeding the flood stage by 0.55 feet. Natural hydrologic modeling, which predicted the height of the river without the Nashville Engineer District's flood control projects in place, showed the river would have reached 55.7 feet without the upstream dams. The flooding would have exceeded the May 2010 flood by nearly 4 feet and came within 0.5 feet of the flood of record in 1927. |
