The water quality of two reservoirs receiving differing amounts of reclaimed water is compared with a neighbouring reservoir receiving none. Monthly sampling of chemical parameters is presented, together with analyses of dissolved and suspended solids (the latter fractionated into sized components). Quantitative estimation of algal populations presented little significant information although measurement of algal growth potential, using Selenastrum capricornutum "bottle test", gave data of considerable importance for reservoir management.
