The weather continues to occur in extremes that interfere with growth and survival of oysters in the Chesapeake Bay. First there was a very wet year in 1979 (some 63-65 inches annual rainfall), much of which occurred in excessive amounts (some 15 inches) between late September and early November. Oysters in the upper James River seed-oyster area were killed by prolonged exposure to fresh or near-fresh waters in fall and winter of 1979-80.
