Alt 2-6d - Fixed Weir w/Dry Floodplain
The recommended alternative consists of a fixed crest weir that is higher than the other two dry floodplain alternatives. It has a rock ramp sloping upstream from the existing dam location. The lock and dam would be removed. A floodplain bench approximately 250 feet wide would be excavated on the Georgia side of the river and would be grassed or paved to prevent erosion. The weir would be 500 feet in width. The water level at 5th St. Bridge would range between 1 and 2 feet lower than today’s conditions with average flow.
