(USGS) is to assess the quantity and quality of the natural resources of the Nation and to provide information that will assist resource managers and policymakers at Federal, State, and local levels in making sound decisions. Assessment of water-quality conditions and trends is an important part of this overall mission. One of the greatest challenges faced by waterresources scientists is acquiring reliable information that will guide the use and protection of the Nation’s water resources. That challenge is being addressed by Federal, State, interstate, and local water-resource agencies and by many academic institutions. These organizations are collecting water-quality data for a host of purposes that include compliance with permits and water-supply standards; development of remediation plans. | Guidelines for Quality Assurance and Quality Control of Fish Taxonomic Data Collected as Part of the National WaterQuality Assessment Program By STEPHEN J.
