A few days ago, there was literally a “watershed” moment for the Atlanta Department of Watershed Management. The tunnel created by Driller Mike began channeling water from the Chattahoochee River into the Bellwood Quarry. The quarry will hold roughly two-billion gallons of water, increasing Atlanta’s drought sustainability with a water reserve from 3-5 days to a month or more.

The quarry is expected to be full by the end of this summer. For a brief timelapse video of the water’s release, please click the picture below.
