The effects of acid deposition on the chemistry of Bickford Reservoir in central Massachusetts are influenced by nearly complete retention of nitrate in the watershed. In contrast to several other north‐eastern U.S. watersheds, stream and water column nitrate levels are very low (∼lμeq/L), and no “nitric acid pulse” has accompanied spring runoff in 2 years of study. Major differences in nitrogen processing among northeastern U.S. watersheds appear to significantly alter watershed susceptibility to acidic deposition and may be of comparable importance to soil depth and mineralogy in the identification of, acid‐sensitive ecosystems.
