RE: constructing ditches. It sounds like you have constructed a french drain when you really need an open ditch. Flatten the sides of the ditch so the top of the ditch is about six or seven feet wide. Bottom width is 1 foot and depth is 2 feet. This will provide a slope flat enough so the rocks will stay in place on the sides of the ditch. Then place the filter fabric on the bottom and rocks on top of the fabric.
