Main Channel?

[william689]

Three water channels from Main Waste Dump need report to a lake (Taillings pond). How should I define my main water channel?
I am working on this design next few days, any comments?

I think your best bet here would be to talk to Nicholas Bugosh, Technical Director & designer of the Natural Regrade module.
His email address is nicholas@geofluv.com

But without further knowledge, you might try beginning the main channel at the head of the middle watershed, and bring the other 2 subwatersheds in as tributaries.
