Research notes

TVA jurisdiction extends to the limits of the Tennessee River watershed including all tributaries — touches the majority of TN counties east of the Highland Rim. Reservoirs include Kentucky, Pickwick, Wilson, Wheeler, Guntersville, Nickajack, Chickamauga, Watts Bar, Fort Loudoun, Cherokee, Douglas, Norris, Boone, South Holston, Watauga, Tims Ford, Tellico, Melton Hill, Fontana (NC), and others. Tenn-Tom Waterway (TCA SE corner) connects to TVA system via Pickwick. State and local permits do NOT substitute for §26a — federal preemption is hard. Local docks-and-shoreline ordinances are advisory; TVA approval controls.
