The Eastern Lake Survey - Phase II (ELS-II) was conducted in spring, summer, and fall of 1986 as part of the U. S. Environmental Protection Agency's (EPA) National Surface Water Survey (NSWS).The NSWS is a contribution to the National Acid Precipitation Assessment Program (NAPAP), which was charged by the U. S. Congress to provide policymakers with sound technical information regarding the effects of acid deposition.The major component of ELS-II was the spring, summer, and fall seasonal surveys and Fall Variability Study of lakewater chemistry in the northeastern United States.ELS-II lakes were sampled once in the spring, summer, and fall at the same location on the lake where the ELS-I sample was collected. In the fall variability study, a subset of ELS-II lakes was sampled on two additional dates at two independently selected locations believed to be the deepest point in the lake. ELS-II data, in conjunction with ELS-I data can be used to assess between-year, within-season, and among-season chemical variability, as well as spatial variability due to site selection.
