“…However, values normally range from 0-4. (Wilhm and Dorris, 1968). After examining diversity in a range of polluted and unpolluted streams concluded that the values of H greater than 3 indicated clean water, values in the range of 1-3 were characterized by moderate pollution and values less than 1 characterized heavily polluted condition.…”

“…The maximum value of (d) depends upon the total number of individuals counted and can be any positive number (Wilhm, 1970). A polluted aquatic environment usually yields a (d) value of less than 1, and a clean aquatic environment usually has a (d) value of from 3 to 4 (Wilhm and Dorris, 1968). Redundancy (r), which is an expression of the dominance of one or more species, can also be calculated.…”

The waters were found to be free of excessive quantities of dissolved nutrients, oxidizable matter, and fecal coliform bacteria.Fish inhabitants include a sizable wild trout population in the upper Sacony basin and a diverse warm-water population, dominated by white suckers (Catostomus commersoni), in the lower basin. A population of 590 trout or 119 pounds per acre (133 kilograms per square hectometre) was estimated for good habitat in the up~er basin. A maximum standing crop of 558.7 pounds per acre (626 kilograms per square hectometre) was measured at one of the more productive reaches.Benthic macroinvertebrate collections tended to support the water chemistry and fish population studies. Diversity (d) and redundancy (r) ranged from 2.44 to 3.46 and 0.14 to 0.38, respectively. Such diversity and redundancy values indicate a healthy environment at all stations.
