AUBURN, Ala. - Near the middle of the Chattahoochee River basin, the idea of a reservoir on an upstream tributary raises "a lot of questions" for a few people. "Maybe at the end of the day it's a good thing, but there's one heck of a lot of question marks," said Joe Maltese, a LaGrange resident. Maltese was among a few people who traveled to Auburn to view Hall County's plans for damming up Flat Creek upstream of Lake Lanier.
