See TVA’s new digital map of the bottom of the Raccoon Mountain Lake

KNOXVILLE (WDEF) – TVA is giving us a look at what they’ve been working on for the Raccoon Mountain Pumped Storage Facility.

Last year, the agency drained the lake on top of the mountain for maintenance.

They took the opportunity to take a 3-D laser scanning device into the bottom to map it out.

Now they are posting the video they built with that information.

 “With old drawings and traditional surveying methods, it would have taken months to map everything the engineers needed to know,” says Keith Elder. “With HDS we had a preliminary map of the section they wanted to start with ready much sooner than we could have had with any other method.”
