Macroinvertebrate annual production was estimated in three Minnesota streams that differed in watershed geologic origin and in total alkalinity. Annual mean alkalinities (as CaCO 3 ) in the Caribou River, Blackhoof River, and North Branch Creek were 34, 83, and 245 mg/L, respectively. Annual production by herbivore—detritivore invertebrates was lowest in the Caribou River (wet mass: 27.0 g/m 2 ), intermediate in the Blackhoof River (36.9 g/m 2 ), and highest in North Branch Creek (119.6 g/m 2 ). Estimates of annual production by invertebrate carnivores followed the same patter: lowest in the Caribou River (5.5 g/m 2 , intermediate in the Blackhoof River (6.5 g/m 2 ), and highest in North Branch Creek (12.8 g/m 2 ). These estimates of annual production were positively associated with alkalinity, nitrates, and fish standing stocks.
