Samples of water, fish and benthic macroinvertabrates collected at 10 sampling stations over a 10-month period indicate that Sacony Creek and its major tributaries contain water of good to excellent quality. The waters were found to be free of excessive quantities of dissolved nutrients, oxidizable matter, and fecal coliform bacteria.
(p>Fish inhabitants include a sizabel wild trout population in the upper Sacony basin and a diverse ware-water population, dominated by white suckers (Catostomus commersoni), in the lower basin. A population of 590 trout or 119 pounds per acre (113 kilograms per square hectometre) was estimated for good habitat in the upper 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 he 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.
