Lake Bottom Study 1999
Hard Bottom

This visual presentation is built upon the lake map provided by Houston Engineering of Fargo, ND that was based upon a software analysis of the 1999 bottom study data. The contours on the lake map provided by Houston Engineering have been color coded for presentation here. The statistics provided here were developed in an Excel spreadsheet using the 1999 data.

This set of images explores the question of "where is hard bottom in Lake Okabena" and presents insights into the patterns of Hard Bottom depths and how much of that potential depth was taken up by water depth and how much was taken up by silt depth in 1999.
