Water Depth (Bathymetry)

A bathymetry map displays the lake floor in three dimensions. The map below was created from data collected on August 29, 2008 by the Lakes Management Unit of the Lake County Health Department. A special thanks to Leonard Dane for this image. The depth has been exaggerated 25% relative to the length for illustrative purposes. On August 30, 2009 the author measured a depth of 18' 5" at the deepest point of the lake.

Periodically, the depth of Gray's Lake has been assessed using a weighted secchi disk and a calibrated rope. The depth of the Lake was probed numerous times during the summer of 2009. The maps on this page contain markers that show the precise lake depth under the icon using GPS coordinates. Click on each marker to see the measured water depth. Be patient, it may take a minute to load the markers on the maps.
