Arc Hydro Burn Stream Slope

[MichaelScott1]

When I use burn stream slope in Arc Hydro, the resulting dataset has elevations ranging from 10 feet to 10,000 feet. They should range from 700 feet to 1,000 feet.

I am using a stream feature class that has the fields "FromElev" and "ToElev" that I have populated using elevations from the original DEM.

I have only found one thread about this and the fix was to use a geodatabase, not a shapefile. I have never used a shapefile for this. I have tried a personal and file geodatabase feature class and have gotten the same results.


Any assistance to get me past this would be great.

The elevations are relative elevations, not real ones. They ensure that the elevations in the streams decrease in the digitized direction. The objective is to obtain correct flow direction grids - you should not use any edited dems as source of elevations for any analyses.
