The Tennessee Valley Authority explains the new fee system to raise rates on marinas and campgrounds using TVA land. The new fee structure starts this January and will only affect owners of marinas and campgrounds that have land agreements with the TVA. Payment will be based on the appraised value of the land and any TVA provided improvements. TVA officials say the increase will make the pay system fairer for the five marinas and campgrounds operating on TVA land at South Holston Lake. (bg)
