There are 40 values recorded in the CV Theis Groundwater Observatory's database as described here. 36 of the values are measured continuously by the CV Theis Groundwater Observatory. The remaining four are measured by the USGS 03274615 gage at Miamitown (about 2.1 river miles and 1.6 air miles downstream from the observatory) and by the USGS 03274000 gage at Hamilton, Ohio (about 17.1 river miles and 13.0 air miles upstream from the observatory).
Adjusted data are most easily viewed on a Windows PC using this dedicated, free application. The instruction manual is available here. The complete dataset may also be downloaded directly in two formats:
