EPA National Lake Assessment Survey Lower 48 States Lake Chemistry
EPA and its state and tribal partners conducted a survey of the nation's lakes, ponds and reservoirs (>10 acres, using NHD) in 2007. This National Lakes Assessment was designed to provide statistically valid regional and national estimates of the condition of lakes. It used a probability-based sampling design (5 size classes of lakes, 9 agglomerated Omernik ecoregions, and spatially distributed across the lower 48 US states) to represent the condition of all lakes in similar regions sharing similar ecological characteristics. Consistent sampling and analytical procedures ensured that the results could be compared across the country. The NLA helped build state and tribal capacity for monitoring and assessment and promoted collaboration across jurisdictional boundaries in the assessment of water quality. 1000 total lakes were included in the NLA (909 lakes visited once and 91 that were revisited), however, the dbase also includes additional lakes for any states that performed an ‘intensification’ in order to do a state-wide lake assessment. Finally, there are lakes that are designated as ‘reference’ lakes that were not chosen in the same probabilistic fashion, but were chosen state-by-state using a variety of methods.

National Surface Water Survey: Eastern Lake Survey-Phase II Combined datasets: Spring (SPSFIM01), Summer (SUSFIM01), Fall (FASFIM01), Summer Chlorophyll (SUSCHLA), and Bathymetry data (BATHYM_M), 1986
The Eastern Lake Survey-Phase II (ELS-II), conducted in the spring, summer and fall of 1986. The focus of ELS-II was on the northeastern United States. ELS-II involved the resampling of a subset of lakes in the northeastern United States sampled in ELS-I to determine chemical variability and biological status. Furthermore, within-indexed period variability was examined in the fall of 1986 to provide insight concerning the ability to detect chemical changes over time, and the precision of the estimates of the number of acidic lakes from Phase I. The primary objectives of ELS-II were (1) to assess the sampling error associated with the ELS-I fall index sample, (2) to estimate the number of lakes with low acid neutralizing capacity (ANC) (i.e. potentially susceptible) that are not acidic in the fall but that are acidic in other seasons, and (3) to establish seasonal water chemistry characteristics among lakes. This data set is part of the National Surface Water Survey (NSWS) and the National Acid Precipitation Assessment Program (NAPAP). The data set contributes to the quantification of the extent, location, and characteristics of sensitive and acidic lakes and streams in the eastern United States sampled during the spring, summer and fall seasons.
