LAKE CHARACTERISTICS:

    Sydney Lake is a Large, deep, cold water lake with a littoral zone covering forty percent of the area and providing habitat for both cold and warm water fish. Thermal stratification was evident at the time of the survey. water temperatures ranged between 70`F. and 45`F. in the upper one hundred feet of water. The ten degree temperature drop (63`F. to 53`F.) between the twenty five and thirty five foot depths identified the thermocline, the layer of water in which there was the most rapid decrease in temperature. The dissolved oxygen content varied very little to the depth of one hundred and twenty five feet, and ranged between 9.4 and 10.0 parts per million. A surface 7.6 pH value showed an alkaline characteristic, in relation to the hydrogen ion composition in the water. A total dissolved solids concentration of 16 parts per million was determined from a surface conductivity reading. Light penetration in this colorless water was indicated by the disappearance of a secchi disc, from view, 26.0 feet below the water surface.
