Steve Koonce, a Civil Engineering Technician with USDA’s Natural Resources Conservation Service (NRCS), remembers swimming in Tennessee’s Cane Creek as a youngster, when he and friends would jump from a bridge into the water 15 feet below. But today, because of a catastrophic erosion problem, that activity would be a lot more dangerous. “Today if you jumped off the same bridge, you would need a parachute,” says the Lauderdale County native.
