Local governments operate many parks around Lanier. (See second and third links below for a listing of all the parks, both on the lake and not, which are operated by the City of Gainesville and Hall County.) In addition to Lanier, the state also operates parks on other federal impoundments in Georgia such as Lake Hartwell and Lake Allatoona.
As for state parks and historic sites, the Georgia Department of Natural Resources, which operates them, says the only affected park is Stephen C. Foster State Park, located inside the Okefenokee National Wildlife Refuge. While this park's campground and cabins remain open, visitors can not boat into the swamp or hike nature trails.
"We've already had a number of campers check into our state parks because they had to leave Corps of Engineers campgrounds which had closed," said State Parks Assistant Director Wally Woods. "We have plenty of cabins, yurts and campsites available this week."
Georgia State Parks that are located on Corps of Engineers lakes, include Don Carter on Lake Lanier, Red Top Mountain on Lake Allatoona, Mistletoe on Clarks Hill Lake, and Tugaloo on Lake Hartwell.
Additional examples of sites not affected by the federal shutdown include:
