Ø West Battle Lake Assessment Report Clarity Results (and other Area OTC Lakes)

                          Secchi Disk Visability Measured in Feet

Secchi disk: The secchi disk is a measure of water clarity. The standard secchi disk is a 8 inch diameter metal plate that is painted with an alternating white and black color pattern. The disk is lowered into the water until it disappears from view. The depth at which the disk can no longer be seen is the secchi depth that is recorded. Secchi disk readings can vary by season with the clearest water generally occurring in the spring, shortly after ice-out. Measurements are usually taken in the summer at the same time the fish sampling is occurring.
