I am making my second attempt to put in a swale on the side of a hill on my property. I want to know: 1) Is its ok if the swale is not perfectly level? 2) Is it ok if the swales are not as wide as your swales? Should I knock out more trees to get the doze in to push towards the swale? (hate to make more bare soil; its winter) 3) Here in Texas US, zone 7b or 8 I want to replace my existing "forest" with a food forest so my plan is to plant this swale then cut the existing trees over time to mulch the fruit trees until there are only food and support trees. Is this a good plan? What would you suggest for replacing a east texas young forest. Im working on a very limited budget so the best I could do is borrow a small dozer with a 7 foot wide blade. Here is what I have so far..230 feet of swale with a holding capacity of about 12,000 us gallons. Enough water flows on the drive in heavy rains to cause erosion. I am redirecting that water towards the swale.. My last topo using a cheap laser level. I have since dug down the high points down.. But still have to raise 65' of swale another 1/2 foot to achieve a holding capacity of 12 inches.
