Many of these problems in lakes and ponds were a result of abnormal runoff and poor pond or lake design. The siphon system provides the most economical means of regulating the water in your pond. No more need in most cases to ever have a pipe penetration through the base of your dam again! Siphon spillway can be classified into two categories.

If the discharge area is where you plan to mow, the pipe should be protected by a series of metal fence posts to keep it out of harms way from a bush hog. Gates also note that siphons constructed on lakes in climes colder than the southeast should have a weep hole drilled in the elbow to prevent it from freezing and plugging the end of the discharge pipe.

Ideally, you would want a pipe large enough to remove water that could be generated during a 25-year rain event before flowing out the emergency spillway. The most common design is a standpipe with a barrel through the base of the dam. Spillway siphons are a great addition to your lake if your primary spillway is a pipe through the dam or your emergency spillway.
