Anatomy of a Pond
A step by step description of how to make two ponds with the smaller one cascading into a larger one.
2 of 30: Bottom part slopes down by about a foot. This will help the top pond flowing down but I will have to raise the other end of the large pond.
5 of 30: Bottom slants down from 2 ft at the top to 3 ft at the bottom for easier drainage. A 2x 4 board and level are used to make sure the sides are level.
6 of 30: Sod has been piled at the top end in a circular shape to make the higher pond (5'L x 3'W x 1.5D). Bottom Pond: 1944 gals. Top: 168 gals.
8 of 30: Bottom pond has an extra 1 ft. hole at deep end for pump and easier cleaning. This would increase the liner size.
10 of 30: My old living room carpet makes a nice cushion for liner. Anything really would do that's soft but avoid newspapers or cardboard.
11 of 30: EPDM liner 16 X 20 ft. for an 8' X 13' X 3 hole. The added 1 foot for the pump made the liner barely overlap sufficiently at the corner.
12 of 30: The heavy liner makes you lose all the graceful curves you made in the pond. Separate top liner
13 of 30: Side view of liner with about 2' overlap. I used the carpet underlay for the sides of the pond under the liner.
14 of 30: Both liners in place. Top liner (8'x10') overlaps the bottom one. Held in place by rocks. A nice flat rock is used just under where the water comes out.
15 of 30: A foot long fold is made in the middle front of the top liner, about 6 inches lower than the rest of the ledge so that the water may flow out.
