Sorry for the late response. Thank you both for the sound advice.I would like to put some ponds at the key points Where the pink circles are, picture one, But with all the red tape involved I don't think that will be an option, so I'm thinking. Maybe give those swales some fall to move some extra water away from that key area or key point to an area that needs more water. And how are rainfall Comes into the calculation. Our soil type is dolma cobbly loam. And our average rainfall is about 13 inches per year.
