I agree, discharge can be a very bad thing. I received a "mandatory Federal Ag survey" recently that asked an awful lot of intrusive questions about irrigation.
Local dirtbike/ATV riding club leases 9,000 acres to ride and has to deal with TDEC whose primary concern with us is silt running in to creeks where we cross. So far they have been reasonable, even delighted every time we build a bridge. We have trouble with nonmember trespassers who think running ATVs and SxS up/down in the creeks is fun.
TDEC has come down very hard on other groups for potential silt in creeks.
