Selected physicochemical properties of Little Lick Creek, in Hartford City, Indiana, were determined in the fall of 1969. Subsurface samples from five stations, two upstream and two downstream from a discharge point: at the. Minnesota Mining and Manufacturing Companywere analyzed. A complex effluent containing a dye entered the creek from the paper plant. Dissolved oxygen and biochemical oxygen demand determinations of the water downstream from the discharge displayed changes in water quality of the creek. The water temperature rose significantly after the discharge water entered the creek. A cell count study of the Cyanophyta of the creek was also determined.Little Lick Creek was considered polluted below the paper products plant discharge based on the observed changes in the water tested. Cyanophyta populations were apparently reduced by the effluent.Ball State UniversityMuncie, IN 47306
