One area had a 3 in. tall barrier along the edge to prevent water from falling, so I was able to avoid putting gutters across this area, and instead put downspouts at either end of the barrier.

Though all the gutters are connected to each other, The catchment area is roughly divided into three sections, one for each downspout and storage area. The water flow to the downspouts is controlled by providing a slope of one quarter inch per foot.  The water from the left side of the roof is funneled along the fence across the yard and into the pond using salvaged 2 inch P.V.C. pipe. The downspout is flexible 2 inch plastic tubing. The placement of the pond was chosen for convenience and to minimize the amount of energy needed to pump the water to the trees and beds around it.
