Matched ecological assessment and stream gaging data for the CONUS Ecological assessment data from the USGS National Water-Quality Assessment Program and the USEPA National River and Stream Assessment were reviewed and records were retained from sampling sites co-located with active USGS stream gages. A limited amount of ancillary data, including location, physical watershed features, and basic water chemistry data for each site were also retained.

The UFINCH application is a computer code that utilizes the geospatial stream connectivity and catchment geometry described in National Hydrography Dataset Plus value added attributes (NHDPlus Version 2) to simulate unit (15-minute) flows in networks of channels, generally by use of daily flows at the most downstream stream segment in a basin at which a USGS streamgage is located. Preliminary testing indicates that UFINCH may be most applicable for simulating unregulated, non-estuarial, flows in basins as large as 3,000 square miles...
