Dailey want to "bring back" Lake Jackson.
Mostly by filling in the sinkhole and any new sinks with dirt and limestone. First off, how well does that actually work? Everything I've read about sinkholes suggests to me that the groundwater will simply eat away at the fill until it, too, is gone. The guy who wants the contract filling in this and other sinks gave an estimate of $100,000 each. I may be wrong, but I would call that the very definition of "throwing money down a well."
Second, draining and refilling are part of the cycle of that lake (and many others in the south). I know our county commissioners don't often seem to know the differences between their asses and a hole in the ground when it comes to the local ecology, but damn. If the Department of Environmental Protection, the Florida Fish and Wildlife Conservation Commission, and water quality specialists all agree that it might be a bad idea, maybe you should actually listen to them.
