ABSTRACT:
An apparatus for use in conjunction with a silt collecting pond to prevent silt from being washed from adjacent land by rainwater comprises a base adapted to rest on the bottom of the pond and a cylindrical cage defining an upwardly open interior volume extending upwardly from the base. A conduit communicates between the interior volume of the cage and the exterior of the pond. Silt cloth is mounted about the cage and a floatable safety lid is adapted to cover the upper opening of the cage. In operation, silt bearing rainwater enters the pond and rises about the apparatus. Water passes through the silt cloth at a predetermined rate such that the water stands in the pond a sufficient time to allow silt to precipitate therefrom. When the pond has been filled with silt, a sleeve is slipped into the cage and a grated lid placed atop the sleeve so that the device thereafter provides for drainage of surface rainwater from the land.
