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.

Non-Data images like this one are tests done along the shoreline to help the test software define the area, or other tests not related to water and silt depths. The non-data tests are left out of the statistical averages, etc. Of the 249 tests, only 219 are valid data showing water and silt depth.

This study was sponsored by the Southwest Minnesota Fishing Club, Nobles County Environmental Services Department, Okabena-Ocheda Watershed District and Nobles Soil and Water Conservation District.
