The first of five public meetings on draft operating plans for the tri-state basin that includes Lake Lanier is set for Monday in Gainesville. The Army Corps of Engineers meeting will take place from 4-7 p.m. at the Gainesville Civic Center, 830 Green St. Attendees will be able to learn about the plans, offer comments and pick up CDs of related corps documents. The current manual for the Apalachicola-Chattahoochee-Flint River Basin was completed in 1958, shortly after Lake Lanier was formed.
