The land is fairly flat and there is no water movement. We only bought the land at the end of the last wet season but we have been watching it for a while. Where the beds are going will end in a big dam to take most of the still water and store it all together in a smaller area. There is a slight enough dip to do this. The beds will just steer it a little (hopefully).
Thanks for the advice, holidays are coming up and i want to get started before the wet season comes again.
