I'm looking to produce a drainage data set, as vector data, from SRTM tif file.  I know I have done this before using the functions in the Hydrology toolbox.  The trouble is, it was a long time ago and I can't remember the process steps.  I'm sure I used Fill, Flow Accumulation, Flow Direction and Stream to Feature as well as the Raster Calculator in Map Algebra.  Can anyone tell me the order in which I use the functions and the required expression in Raster Calculator.  Thanks
