Hello. Thanks for mapping on this project. 
A remark. You tagged small waterways as ditches which is not correct. Ditches are human made waterways,  See this web page.
https://wiki.openstreetmap.org/wiki/Tag:waterway%3Dditch

the correct tag should be waterway=stream ( when it is that narrow that you can jump over it), Otherwise river. You can add intermitting=yes to it when it is often dry.
Also, the flow direction matters. In your situation, the flow is upwards .
Load the opentopo map imagery and check the topo hights.  Downstream is to the north,
Best regards
