619'

Minimum permanent pool - (I have never seen it this low)

620'-632'

Water is low, cliffs are high, many places such as Burgess Falls are inaccessible. Docks at the boat launches at Edgar Evins State Park are probably on dry land. Beaches are exposed. This means cliff diving by day, fires on the beach at night.

639'

Minimum depth allowing access to Burgess Falls area.

643'

Minimum depth allowing access through shortcut to Davis Island and Cookeville Boat dock area. Shortcut is across from TN Tech Dock, before you come to the narrows going south

646'

Minimum depth allowing access (of small cruisers and ski boats) to area area directly below Burgess Falls (as depicted in this photo)

647'

Minimum Depth required for access past the beach area at Rock Island State Park to the turbulent waters a few hundred yards below Great Falls. I have traveled to within sight of the falls with the lake as low as 643' but this is not recommended. Rocks lurk just below the surface in places and you'll need to post a lookout to boat past the island.

648.5

'Comfortable' access to area directly below Burgess Falls and close access to Fancher Falls in Taylor Creek.

650'

At this level and up be aware of floating logs and debris.

657'

Launch ramps at Centerhill Marina are inundated and useless, head to Edgar Evins.

660'

Highest I've ever seen it.

685'

Maximum pool.
