Some effects of the introduction of hard water into Carvin Cove Reservoir, Virginia
… in the area near the hard water inflow. Length-weight relationships and condition indices suggest that bluegills and bullheads were in better physical shape in 1968 than they were in 1951. An age and growth study on the white sucker, Catostomus commersoni, indicated that growth rates had doubled …
