The Rivanna Water and Sewer Authority is looking at building an earthen dam for Ragged Mountain Reservoir, Brian Wheeler writes for Charlottesville Tomorrow. It would be built downstream from the existing dam, but taller, allowing an extra 45 feet of water in the reservoir. This is instead of the prior plan, which called for a concrete dam. That would have cost between $70M and $100M; this new one would run between $29M and $37M. The RWSA has not yet determined if they’re going to build a dam, extend the existing one, dredge the reservoir, or do nothing at all.
