What Today's Water Level (1069.9 ft) Means

Boat Ramps & Navigation

At 1069.9 ft MSL, main public concrete ramps remain fully functional with sufficient trailer draft. Boaters should exercise standard vigilance around shallow sandbars when straying outside marked navigation channels.

Private Docks & Shorelines

Water line is situated 1.1 ft below normal conservation pool. Floating docks and gangways are operating at optimal gangway slope without mud grounding.
