A new hypolimnetic aeration system is described. This system increased the hypolimnetic oxygen concentrations of Lake Waccabuc, New York, from 0.0 mg/1 to over 4.0 mg/1, while at the same time preserving thermal stratification. These improvements and others created a suitable habitat for cold‐water fish, but care must be exercised in the use of the system to avoid problems of nitrogen gas supersaturation.
