Thanks for all the quick replies.

Davedavidson1,
The source of my water will be coming from rain or a pump from water at my house.

I am in the process of creating a layout using smart draw trial version.

Once I get this ok'd I will start looking into locating a professional pond builder.
Btw I have searched the net for a local one but couldn't find anyone. Is there another way of locating someone for this.

Thanks
