Macrobenthos and physical/chemical factors known to affect them were monitored near Calvert Cliffs on the mainstem of the Chesapeake Bay (1971-1984). These data, along with data collected near Morgantown on the Potomac River (1980-1984), were used to quantify variation in macrobenthic abundance due to spatial patterns, season, year, and power plant operations. Macrobenthos were persistent within bounds determined by year-to-year variation in salinity and dissolved oxygen. All species responded to anoxia by declines in abundance. Species that prefer high mesohaline salinity increased in abundance at Calvert Cliffs; freshwater and estuarine species increased in abundance at Morgantown.
