Effects of an Extreme Flood on Aquatic Biota in a Catskill Mountain River. Summary Report.

摘要

This project investigated the response of fish and macroinvertebrate assemblages and the standing crop of periphyton (algae and other microorganisms) to a catastrophic flood in the Upper Esopus Creek in the Catskill Mountains of New York. The severity of the impacts, degree of recovery, and the landscape or hydrologic characteristics that may have afforded resistance or resilience to local assemblages were assessed. Factors that influence physical habitat, hydrology, ecosystem condition, and water quality in the Upper Esopus Creek are important because this system supports premier brown and rainbow trout fisheries and it channels approximately 40 percent of the New York City drinking water supply.
