Field notes
As of Oct 25, 2026, Oologah Lake stood at 640.50 (NGVD29) ft.
The lake is 2.50 ft above its conservation pool elevation of 638.00 ft, meaning water is being held in flood storage.
The level has been roughly steady over the past week (−0.01 ft).
Compared with a year ago (638.67 ft), the lake is 1.83 ft higher.
Readings are the hourly pool elevation the U.S. Army Corps of Engineers publishes for Oologah Lake near Oologah, OK (SWT); changes compare readings at the same hour.
The Corps' flood-control pool runs from 638.00 ft up to 661.00 ft, so about 11% of that flood space is in use (our calculation from USACE levels).
