Multiple maintenance techniques aim to improve conditions on Chautauqua Lake for its many uses and users.
For decades Chautauqua Lake has been managed by a combination of mechanical, chemical, and biological techniques. These include shoreline and debris cleanup, mechanical plant harvesting, herbicide treatment, herbivores, and dredging, among others. Please see below for a list of resources related to in-lake maintenance programs, past and present.
