We have some rain catchment that i use to water trees, but its not nearly enough because we have lots of young trees and plants that dont yet have established root systems. I'd like to get more rain catchment.

Yes, many rainwater catchment tanks (15k gal total) Series of berms and swales downslope of deep litter piles (large chicken run and hugel piles) to help filter water that flows down to us from houses above Deep mulch (almost 1' deep at this point over heavy clay) and infiltration basins anywhere there was runoff Redirecting driveway runoff to debris filled tree basins with water bars (mostly at 45's) All lawn is bordered by mounds of mulch to get the water to slow and sink into the grass and tree roots Probably not as doable on larger acreages but works well for our urban homestead. Our last big rain event in July caught over 100,000 gallons of water with no runoff. I may play with some small ponds next, have 2 separate micro key points that could be ideal..

Nice. We have keyline swales installed in our grazing system that will be covered and do mention ponds as well!
