Knoxville, TN (WOKI) A popular swimming hole in South Knoxville will remain closed for the time being following a dangerous rock wall collapse over the Memorial Day holiday weekend.

Officials with Ijams Nature Center announcing Thursday that Mead’s Quarry Lake will be closed longer than expected after a portion of the rock wall at the back of the attraction came loose, falling into the lake.

“I know everyone wants to swim, and we’re all ready for a fun summer at Mead’s Quarry, but safety comes first. Please give Ijams time to do the necessary work to create a safe summer for all patrons. While we understand the eagerness to enjoy Mead’s Quarry, safety remains our top priority,” said CEO of Ijams Nature Center Amber Parker. “We kindly urge visitors to respect the designated boundaries for their own well-being and the safety of others. Any violations will result in immediate removal from the premises.”

After consulting with a geology expert, representatives say they plan to expand the “no-go” area to ensure that people are well outside the rock-fall zone and to install new buoys to replace those damaged by the rockfall.

“The rock walls of any quarry are unstable places,” Parker said. “During the quarrying operations, they were blasted by dynamite for decades, which created cracks and fissures throughout their surface, allowing rain to enter. Natural freeze/thaw cycles then work on those areas until the rock is weakened enough to fall. Rocks fall from those walls every day, which is why it’s so important to respect safety signage and designated ‘no-go’ zones.”

Ijams officials say they hope to have the work completed and to reopen the lake by June 5 or 6.
