Official elevation · Clearly timed
Current elevation, recent movement, dam outflow, and a multi-year comparison—organized from official USGS and U.S. Army Corps of Engineers data.
Reported Oct 23, 9:00 PM CDT · NGVD 1929
Guide elevations shown in the Louisville District daily lake report are planning references, not a promise that the lake will remain at a particular level.
Compare by calendar date
Read the number correctly
The reading is the lake surface elevation above the NGVD 1929 vertical reference—not the number of feet of water beneath a boat or dock.
The displayed time belongs to the source observation. A delayed label means the newest official reading is older than the normal live window.
The 24-hour and seven-day changes show whether the lake has risen or fallen between comparable official observations.
The same lake elevation can affect ramps, coves, docks, and shoreline access differently. Use the lake map and ramp details for the place you plan to visit.
Source & reliability
TARR uses the lake-elevation series for USGS monitoring location 03318005 as the primary current reading. That station is operated by the U.S. Army Corps of Engineers. The Louisville District’s public CWMS series provides a second official path and the current year plus two completed years of comparison history.
When neither official source provides a recent valid value, this page says the reading is unavailable instead of presenting an estimate as current fact.
