EPA reach files

From EPA Basins site (http://www.epa.gov/OST/BASINS/).  Click on Downloads, then BASINS GIS data. Click on the state (Idaho in this case). 
Click on link to download reach file version 3 and save to disk.  The resulting 17050103_rf3.exe is a self extracting zip file that contains the 3 files comprising the shape file.

Digital Elevation model.

From USGS (http://edcwww.cr.usgs.gov/doc/edchome/ndcdb/ndcdb.html).  Click on 1:24,000 DEM then FTP via Graphics.  Click on the map to zoom in.  Click on individual map units desired.

Reynolds Creek Watershed is encompassed by Soldier Cap, Wilson Peak, Rooster Comb, Reynolds, De Lamar and Silver City.  Download the zip file for each.  Uncompress.  Use SDTS DEM to ArcView Grid Conversion Utility (http://hydrology.usu.edu/dtarb/SDTSext.html) to import these in to ArcView.  Use Grid Merge script included with SINMAP (http://hydrology.usu.edu/dtarb/sinmap.htm) to merge into a single DEM.  Fill any gaps at boundaries by averaging.  Then the resulting file was Exported as ASCII.
