Box-type parallel-bar barriers are appropriate for hooded inlet, drop inlet and culvert-type overflow pipe spillways (box-type barriers were addressed in an October 1997 Ag News and Views article, Box-Type Parallel-Bar Barrier.

Eventually, they corrode and leak, the pond water level drops, and, in extreme cases, erosion around the failing pipe can tear a hole in the pond dam and destroy the embankment, flooding the neighbors downstream. 23.

Often spillways will support growth of native aquatic plants like cattails. I suggest using a bottom orifice between the storage node and the upstream node of the discharge pipe. The Pond Leveler pipe then becomes a permanent leak in the dam so the beaver pond is controlled at a safe level despite the presence of beavers. These may have partial levees with one side open to receive surface runoff from rains. as plastic pipes are flexible and smooth inside, they can deform slightly
