Real-time stream flow data is collected from over 8,000 on-line stations throughout the U.S. A "Water Use" Web site has maps and searchable data by county and watershed. A great place for a school project! On-line databases provide data and reports on acid rain, atmospheric deposition and precipitation chemistry, and information about the transport of sediments and contaminants in stream.
