Abstract:
In ponds and small lakes having standpipe overflows, a method of complete pond management including preventing of clogging of the overflow from debris, preventing loss of fertilizer added to the pond to promote fish growth and addressing environment concerns comprising:installing a capped sleeve having at least one exterior valve means communicating with the interior of the sleeve over the standpipe and providing standoff means in the lower portion of the sleeve to hold the sleeve in predetermined spaced relation with the standpipe, the cross-section area between the sleeve and the standpipe being equal to or greater than the cross-section area of the stand pipe;leaving the valve means open to equalize atmospheric pressure from the interior and the exterior of the capped sleeve whereby pond overflow into the standpipe will remain normal;closing the valve means to prevent equalization of atmospheric pressure from the interior and exterior of the capped sleeve whereby water flow will create vacuum within such sleeve to raise the water level above the top of the standpipe to completely fill the standpipe with water whereby the standpipe will flow fully which will drop the level of the pond until air enters the bottom of the sleeve to break the vacuum and stop the overflow.
