The sinkhole on White Rock Lake Trail has been repaired, and the trail is open again between Lawther Drive and the spillway, according to a statement from Dallas Park & Recreation.
A section of the trail was closed because of the sinkhole near the spillway and San Rafael Drive that was estimated to be 20-40 feet deep. It emerged on March 6, and parts of the trail were closed last weekend, according to a Dallas Observer article. After reopening, Dallas Park & Recreation announced on Monday, March 9 that the trail would be closed between Lawther Drive and the spillway.
A screenshot of an email from Cam Loos, Dallas Park & Recreation assistant director of planning and facilities, addressing the sinkhole circulated on Facebook. The message speculated on the size of the hole and said that the cause has to do with an abandoned sewer line that needed to be backfilled, which is what happened.
The City told The Dallas Morning News, which described the sinkhole as 14 feet deep, that the area will be monitored for ground movement. White Rock Lake Trail may need to be closed in part in the future so that crews can fill the abandoned pipeline with grout.
