What is the purpose of the spillway?Is ther water flowing in and out of your pond, and this is for over flow conditions? Or is the spillway there to drain the pond when necessary? How is the pond filled, hose, rain or creek?

Dad has ponds that were dug in the 40's and 50's with creeks flowing iin and out. These are in a cedar swamp. They have 15" to 18" dia culverts on the outlets. There are two steel rods driven in to the bank vertically at the edges of the culverts. Boards can be placed in between rods and culverts to raise water level. Yes, some water gets by, but it has to anyway. We have actually shut off the water flow when we need to work in the creek below the ponds.

On your boards. How about lining your 2x8 PT boards with white trim metal (or whatever color your prefer). Width would be about 8 inches. That extra 3/4" could overlap the lower board. With some type of water seal, grease, foam, etc, maybe the overlap would slow down the water leaks. Or maybe some overlap joint cut into the 2x8's. Just some rambling. Jon

You know those black foam rubber tubes that are used to insulate water pipes. They are slit down their entire length. Find the right size and slip one on the bottom of each board. Then a thick layer of foam insulation on the downstream side of C-channel where the boards go.
