The red numbers
1 to 7 designate 1952 borings for
which the data could not be read.
The blue numbers 8 to 14 designate 1952 borings for which there is valid data.
The black numbers 15 to 59 represent 1956 borings.

The 1952 and 1956 core borings of the bottom of West Lake Okabena were both documented on the same large lake map. This map and data came from files in the Soil Conservation District Office. The data was transferred to the attached spreadsheet for use here. The position of the numbers on this lake map correspond to the location of the core borings. The background view of the lake is a more recent satellite view of Worthington, not from the 1952-56 era.
Elevation above sea level is used to help make these studies comparable even though they were done when the water was at different levels.
The 1952 study ( boring numbers 1 to 14) was done when the water surface level was 1576.09 feet above sea level. The 1956 study (boring numbers 15 on) was done when the water surface level was 1573.2. The dam runover level is 1576 feet above sea level.
