I'm trying to build a Geometric Network to run my Arc Hydro analyses on NHDPlus Data. When the process of making Geometric Network finishes Arc reports "Drainage_Net_BUILDERR" error table has been created. I checked all 10 ObjectIDs listed in the table and it seems like they are small loops/single lines attached to the rest of the stream network. I'm wondering if I should ignore the error and continue my analysis or I should remove the small loops/single lines from my analysis. Attached please see a screenshot of the table and sample error lines.
Thank you for all your help.
