Fish population studies were conducted in the Monongahela River during the period 1967-1973. The results of these studies were evaluated in relation to trends in water quality. Comparative fish population statistics obtained from the upper Monongahela River shows zero fish in 1967 and 8,071 fish in 1973 at the same location. The same type of data obtained in the lower Monongahela River reveals a change of 20 fish in 1967 to 869 fish in 1973 at the same location. Intermediate data obtained in 1968, 1969 and in 1970 substantiates the gradual increase in the fishery resource. The data indicate significant improvement of water quality in the upper portions of the Monongahela River and less improvement in the lower portions of the river.
