Special Lake Information & NoticesNormal Lake Conditions In Sight
The long-term lake levels and discharge forecast from TVA's River Forecast Center continues to call for a downward trend over the next week. In fact, this time next week, Kentucky Lake is forecast to be near winter pool with only 110,000 cubic feet per second being discharged. Unless we receive more rain or if flooding ramps up on rivers downstream, we expect the lakes to be where they should be by the end of the month.

Explanation of Values
Water temperatures are reported from Hancock Biological
Station on Ledbetter Bay at Kentucky Lake and are measured
at the surface.

Change - this shows the difference in the past 24 hours.
Normal - this shows the departure from normal.
cfs = cubic feet per second, which is the amount of water that is discharged through the dams.
Water Clarity - "stained" means some murkiness
or discolor in the lakes. "Normal" means typical
clarity, usually 3-4 feet for Kentucky. "Muddy" means
no clarity at all.
Lake elevation is based on sea-level. Strength of current is based on the discharge rate at the dams. Kentucky Lake is much larger than Lake Barkley, so 100,000 cfs at Barkley Dam produces stronger current than 100,000 cfs at Kentucky Dam. Use this unofficial chart to compare current strengths.
Lake elevations and current forecasts are provided in real-time from TVA and the NWS.
