A draft document detailing the proposed Glades Reservoir’s environmental impact now is slated for a June release instead of February, as earlier projected. “This schedule change resulted from additional time needed to analyze data affected by the update to the application,” said Russell Wicke, spokesman for the U.S. Army Corps of Engineers, Savannah District, in an email last week. He noted that Hall County “had provided an update to its application reflecting a revised project configuration.”
