Characteristics of lakes in the eastern United States. Volume 1. Population descriptions and physico-chemical relationships

A water sample was collected from each of 1612 lakes. This subset of lakes was selected from within three regions of the eastern U.S. (the Northeast, Upper Midwest, and Southeast) expected to exhibit low buffering capacity. Each region was divided in subregions. Subregions were further stratified by alkalinity map class. A suite of chemical variables and physical attributes thought to influence or be influenced by surface-water acidification was measured for each lake. The results of these measurements and data analyses are described in the report.
