Real Time Stream Flow Data


Not only is it necessary to compute the concentration of a certain contaminant in a stream, but the total amount , or load, of a contaminant need also to be determined.  In order to do this, the flow of the stream must be known.  The USGS has real time stream flow data for the following stream locations that were sampled:
