Recent studies show that road salt inputs are affecting aquatic ecosystems. With the addition of salt to freshwater lakes, density differences increase between surface and bottom waters and more energy is needed to cause mixing in the spring and the fall. The aim of this study was to determine if local lakes show evidence of salt accumulation and if this is reducing seasonal turnover. We measured oxygen and temperature in the spring and summer of 2015 to determine the degree of turnover, and measured nutrients and chlorophyll in the epilimnion, metalimnion and hypolimnion. We found that more strongly stratified lakes had greater nutrient concentrations in the bottom waters. Our results indicate that even lakes without high salt concentrations showed signs of reduced turnover. These findings suggest that small deep lakes may be particularly susceptible to further reductions in mixing if salt inputs increase.
