Looks like you have quite a bit of momentum in this direction. If you run into any bumps and are willing to entertain a "natural" lining option we'd love to help out. We're headquartered here in Phoenix, AZ and I can put you in touch with Ron Ciardella our Vice President of Field Operations. We've worked with a lot of fisheries, lakes, and ponds over the years

This looks like a nice project.
