Hello,

I am using arcgis pro 2.5.1 to run an acpf assessment for a HUC12 watershed (Kyle Prairie Creek 041000070602) in North-west Ohio. I am getting an error when running the Stream Reach and Catchment tool. I have recently updated the acpf toolbox as of 6-16-2020. I used the tool before with no problem, but I am not sure what the problem is this time around. Failed to execute (CalculateStatistics). I reclassified the perennial streams to 1, saved the edits, and made sure there were no features selected before running the tool.

Error:

I get the same error when running the PDFlowNet output as well.

Any ideas what I am missing here?

Thanks,

Hi Matthew

A failure on the calculate statistics following a TauDEM command suggests that the output does not exist. Please the the TDProcDir that is in the scripts folder under the ACPF toolbox location. You may benefit from a new ArcGIS Pro project being used and/or a reboot.

replacing the part of the script that was trying to calculate statistics on the shapefile worked.

#TDStreamReach = arcpy.CalculateStatistics_management(TDProcDir + "\\TDStreamReach.shp")

TDStreamReach = TDProcDir + "\\TDStreamReach.shp"

Thanks,

Matthew
