Calcite dosers were tested in 1988 on three Maryland Coastal Plain streams subject to acidic pulses during precipitation events. Increased flow during precipitation events resulted in depressed pH, ANC and Ca concentrations and elevated A1 levels in untreated sections of each study stream. Water quality in areas of each stream receiving calcite slurry was maintained near baseflow conditions. In situ survival tests were performed on yellow perch and blueback herring. Adult spawning surveys, ichthyoplankton collections, and juvenile surveys showed several migratory fish populations to be near historically low levels in four of the five streams sampled in 1988.
