Dylan,

   All data are Oregon Lambert Conformal Conic. x,y distances are in metres,
z in international feet. I specify the zmult of 0.3048 or the module does
this automatically.

   The drainage basin has an area about 12,000 acres. There are portions of
surrounding basins in the window, but I'm interested only in the one basin.

   The attached screenshot has the DEM, basin boundaries, streams, and other
features too small to see at the reduced scale.
