Autor: Patrick L. Hudson, Norman G. Benson
Publikováno v: Transactions of the American Fisheries Society. 104:526-528
Lake Francis Case, a 356-km2 Missouri River reservoir, is drawn down each fall to hold water released from upstream for winter power generation. The customary drawdown of 10-12 m in 1953-70 was reduced to 6-7 m in 1971-73. Benthos samples collected f
