Below are the temp./depth readings taken from 2 ponds in cent. Miss. on 8-21-05 after a normal summer including 14 days +- of over 95/100 temp/heat index. Pond 1 = 6.5 acres, pond 2 = 16 acres. Both are fertilized to an appx. 18in. visibility and both are spring fed (near surface in min. amt.)just about enough to offset evaporation. Sorry no DO readings but am looking into that-- anyway that would spoil the fun of the test. Temp. readings are averages at depth. No aeration . Underwater camera gives temps. and reveals on IR lights much floating/suspended matter at all depths. These ponds avg. 6-8 degrees cooler than others in area unknown speculation as to why.

Sonar revealed fish at all depths down to 13 ft. but most were on cover in open water 3-8ft.I would like any comments or thoughts on what you think including where you think the thermocline is if there is one. ewest
