Project 1: image 2

45 mil EPDM Fish Safe liner (with a 20 year manufacturer's warranty to not break down even if in full sun) and underlayment are being put in place. The falls box is in place and the falls have been built. We used rounded boulders to cover the liner and act as a retaining wall to keep the edges from collapsing inward. We have since changed to field stone, a flat rock that allows more stable stacking and appears more natural for Missouri waterways.
