The open end of any AquaDam® should always be tied off to the bank that is supporting it. Cutting a hole with a knife and simply putting a rope through it will always be the fastest way to tie off your dam. However, the following pictures will show you the best method to tie off your AquaDam®.

Find a medium sized rock and fold some of the outer material at the end of the AquaDam® around it. Make sure that you don't also grab the inside tubes.

Make sure the material completely surrounds the rock.

Place a loop of rope around the piece of material containing the rock.
