A well that could provide Lake Lanier Islands with all the water the resort would need is nearing the end of the testing phase and, as of now, all signs are positive. According to Bill Donohue, the executive director for the Lake Lanier Islands Development Authority, the well underwent a 72-hour “pumping test” that wrapped up late Saturday. Sensors will stay in the well until Wednesday to make sure it fills up properly, but so far, so good, Donohue said.
