The images with the RED border are those spots where SILT depth is greater than water depth.
Depth water and silt depth figures shown in white are in FEET. The left column black figures of 1540 to 1576 are elevation above sea level. The numbers at the bottom of each column are the original test shot number assigned on the day the study was done.
