Wow glad to hear from you. Been kinda holding back until I do more research. I think I am going to build the water falls first. I am going to Rome Georgia to Berry collage to look at a 45 ft water wheel in the next few weeks and then to Alexandera , Alabama to look at a 35 ft water wheel. There is one about a mile from my sons home that I am going to try and get permission to visit in Lee County near Opelika , Alabama. I want to take a close look at some of the ones that ran factories many years ago. How large is the creek that you put your oak spiral water wheel pump into???? Do you have flow the year round? My 8 acrea lake is down abut 3 feet and I want to be able to pump water out of the 12 acre lake up about 12- 15 feet verticle to help keep the 8 acre lake full. richey
