JOHNSON CITY, Tenn. (AP) - The original sinkhole discovered at Boone Dam has been repaired, and the Tennessee Valley Authority is installing a device to monitor any new movement in the area.

Media outlets report that the TVA also announced 24-hour work began at the site on Monday.

A sinkhole at the base of the dam was discovered in a 2014 inspection. In July, TVA launched a $200 million-$300 million project to repair the dam, a process expected to last at least seven years.

On Monday, the TVA completed the first phase of the project with repairs and drainage improvements just downstream from the dam.

At the site of the sinkhole, the TVA installed a solar panel and equipment box for a piezometer, a device which measures the pressure of groundwater at a specific point.
