A DATABASE FOR FOR EVALUATING E-FLOW HYPOTHESES AT REGIONAL AND NATIONAL SCALES: LIMITATIONS AND POSSIBILITIES
Ideally, e-flow hypotheses are tested using concurrently collected ecological and hydrological data. However, because streamflow monitoring networks are sparse and rarely targeted for ecological assessments, there is a need for a database that contains uniformly collected ecological data at locations with active streamflow gages. We describe a nascent effort to assemble such a database using ecological assessment data collected by two national programs: the National River and Streams Assessment (USEPA) and the National Water-Quality Program (USGS). We assembled invertebrate and fish community data collected by these two federal programs from 1993-2009, and manually matched sampling locations to active USGS stream gages. A total of 728 stream gaging stations were matched to biological community samples. The matched sites represent a broad size range (area 1-1,020,806 km2) of streams and rivers across the contiguous US. We provide summaries of the streamflow records and environmental settings of these sites, evaluate potential issues with taxonomic consistency, and demonstrate two applications of the database. Finally, we discuss the potential for expanding the database by including biological and hydrological data collected by other federal and non-federal sources.
