This is really great!
I love seeing how it is in action, please keep the pictures coming.
Also, what does it mean "on contour" swales?
I know it means on contour with the land..but what does that MEAN?
GP - thats great to see !
What is your annual rainfall there and do you plan on mulching the swale?
Please keep us updated as it progresses.
I plan similar on land with just a slight slope and the swale will be lower in height but with a "basin" for individual trees planted on the downhill side.
