TIME (Temporally Integrated Monitoring of Ecosystems) is a statistically selected population of lakes in New Eng- land and the Hudson Valley (31 lakes) and the Adirondacks (43 lakes) that were selected from the original 1991 EMAP-SW (Environmental Monitoring and Assessment Program–Surface Waters) population with acid neutralizing capacity less than 100 meq/L (Young & Stoddard 1996). Samples are taken annually, during a summer base-flow ‘index period’. This sampling strategy is used to reduce hydrologic impact on water chemistry and hence provide an assessment of trends in chemistry with the least number of samples (e.g., Stoddard et al. 2003).
