Lakes of New York State, Volume II: Ecology of the Lakes of Western New York intensively studies four lakes in the New York State—Chautauqua Lake, Onondaga Lake, Oneida Lake, and Irondequoit Bay. This book is divided into four chapters. Chapter 1 reviews the historical data of Oneida Lake that has a large base of 206.7 km2 and relatively shallow depth of 16.8 m. Irondequoit Bay is described in Chapter 2 as a lake with great recreational potential despite large inputs of municipal wastes to its tributary streams. Chapter 3 categorizes Chautauqua Lake as a productive fishery and recreational resource. Onondaga Lake is recognized in the last chapter as a receptacle for waste products due to man's abusive activities on its shores. This volume provides interesting case studies for students or professionals interested in the impact of the activities of mankind on lakes.
