New tool - Miscellaneous Hydrology Tools for ArcGIS

I've got a new tool out.  It is a collection of miscellaneous hydrology tools called, appropriately enough, Miscellaneous Hydrology Tools for ArcGIS. You can download it HERE. This toolbox runs in ArcMap and performs three specialized functions that augment the standard hydrology toolset in Spatial Analyst. These tools include 1) Find Inflow Cells, 2) Trace Path, and 3) Find Longest Stream in a Watershed. In the next three posts I intend to detail how these tools work and how they can be applied to solve common problems.
