REVISIONS HISTORY -
Revisions: Land-surface datum was updated to 1,296.65 ft NAVD88 on May 22, 2023, as determined by a GNSS survey by Missouri DNR. Land-surface datum was previously published as 1,290 ft NAVD88 from topographic map. Discrete water-level measurements prior to May 22, 2023, are referenced to the original datum.

The record from 09/28/2009 to 12/01/2009 was modified after it was previously set to 'Approved' status. A prorated correction from +0.02 to +0.07 ft was applied during this period to smooth the hydrograph after the gage reset on 12/01/2009.
