John Boudreaux, director of Assumption Parish Office of Homeland Security: Lake FUBAR is at least 500 feet down
Texas Brine spokesman Sonny Cranch: Our depth survey says Lake FUBAR is 110-220 feet down.
The Advocate has this: “Boudreaux said he did not use a sophisticated method like sonar to measure the sinkhole. Instead, he said, he took a 10-pound crowbar with the ends cut off and attached it to a 500-foot surveyor’s tape measure, drove out to the center of the sinkhole in an amphibious vehicle and let the crowbar go, unspooling the tape measure until it could not go any further.”
