The Chesley Lake Lung is an innovative lake restoration system designed to improve water quality by increasing oxygen levels in the deep waters of the lake.

Operating since the 1980s, the Lake Lung helps support a healthier aquatic ecosystem by delivering oxygen to areas of the lake that would otherwise experience low oxygen conditions during the summer months.

The project represents decades of community commitment to protecting and enhancing the health of Chesley Lake.

The Lake Lung uses a process known as hypolimnetic oxygenation.

Air is introduced into the deeper portions of the lake through a specially designed system that increases oxygen levels while minimizing disturbance to the natural temperature layers of the water.

By improving deep-water oxygen conditions, the Lake Lung helps support aquatic life, nutrient cycling, and overall lake health.

While the Lake Lung plays an important role in maintaining water quality, it works best when combined with responsible shoreline stewardship, septic system maintenance, and environmentally responsible practices throughout the watershed.
