Glad to help.
Here's another thought. Fill the swale with pipes suitable for burial, pour some concrete to stabilize them and cover with fill dirt & topsoil & sod. Now you have an underground stream.
Or see if these people
or some other company make flat, corrugated, coated sheets
capable of supporting enough pounds per sq. ft.
Then cover the swale with several of these sheets and cover with fill dirt & topsoil & sod.
