https://community.esri.com/t5/water-resources-questions/error-010151-create-overland-flow-connectors/m-p/1045405#M4020 <P>I am using ArcHydro for the first time and am following the protocol from the Stormwater Preprocessing and Analyses Manual and I have run into an error when trying to use the Create Overland Flow Connectors. I've attached a picture of the error message. I haven't deviated from the instructions in the manual (other than having to use Trace Network instead of the geometric network tool used in the QA/QC section) and have not run into any major issues yet so I'm not sure what's behind this error. I checked all of the attribute tables for the inputs just to verify they weren't empty and they're all as they should be. I just recently updated my pro to 2.7.2 and installed the most recent patch and am using ArcHydro 2.7.19</P> Fri, 09 Apr 2021 12:48:08 GMT EmilyTaylor 2021-04-09T12:48:08Z https://community.esri.com/t5/water-resources-questions/error-010151-create-overland-flow-connectors/m-p/1045405#M4020 <P>I am using ArcHydro for the first time and am following the protocol from the Stormwater Preprocessing and Analyses Manual and I have run into an error when trying to use the Create Overland Flow Connectors.
