This layer is intended to match the 10 meter DEM, for modeling purposes. It may not be representative of the true watershed boundaries.
A lattice was generated using the 10 meter DEM of the HJ Andrews and surrounding area.
The sinks were filled on the lattice, and a flow direction grid was generated. A flow accumulation
grid was also generated. The flow accumulation grid was used to adjust the gps locations of the gaging stations to cells where they would draw the watershed correctly. The gaging stations were converted to a grid layer, and snappour was used. The grid watershed command was used to create the watershed boundaries. There were problems with watersheds 8,9, and 10. Adjustments were made to watershed 8 gaging station to get a better deliniation of the watershed. It was decided to use the existing boundary for watershed 9 as the 10 meter DEM representation was not working (it appears to be due to errors in the DEM). Watershed 10 was drawn too large, so the old southern boundary was used with the 10 meter DEM boundaries to make a better representation. The data was converted to a polygon coverage (from a grid), cleaned up, and attributes were added.
