Reach File Phase II Report: A Standardized Method for Classifying Status and Type of Fisheries

摘要

The Reach File is a computerized catalog of the hydrological features of the United States. The file will organize and analyze water resources data and provide interpreted information concerning physical, chemical, and biological attributes of the cataloged river reaches. The objective of Phase II was to design a standardized system for collecting information related to the type and quality of fisheries in the cataloged reaches. Fisheries type is determined by the species present, relative fish abundance, habitat categorization, and other parameters. This system will aid decision makers to retrieve water related information on a specific stream reach to assess existing and potential impacts or monitor the results of water pollution control or water resource development activities.
