Water, Water, Everywhere - and what we know about it
Ten Mile Lake holds an estimated 21,635,369,472 gallons of water within its 21 miles of shoreline. The TMLA has been studying that water for almost 75 years, and we continue to do so to ensure its health into the future. On this page you will find the latest depth and temperature readings, results of Secchi disk readings, thermocline depth and zebra mussel updates.
