The spillway has washed out and it has Stone dumped in it I plan to build a dam where I can regulate the amount of water flow right now the water just runs through the rocks but I have about 1500 feet of stream and from the spillway to the edge of my property there is a 20'elevation difference. I don't know what size generator I need I just want enough to run a small house I also plan to have a couple wind Mills and some solar panels I would like to not use someone else's electricity at all. I'm not sure what kind of wheel I will build that's why I'm here asking for suggestions I think I can easily get a 10 foot drop by building a dam and moving some dirt I have a dozer
