Abstract
A decorative pond which includes a pond area, a water feature for discharging water into the pond and a skimmer construction for receiving pond water, separating debris from the pond water and recirculating filtered water to the water feature. The skimmer construction includes: a housing which defines a fixed pond-water receiving aperture, an internal assembly positioned adjacent the fixed aperture defines a movable pond water receiving aperture that is selectively positionable relative to the fixed aperture. The combination of the fixed and movable apertures define an inlet opening to the skimmer for receipt of pond water in said housing. A debris collection member is positioned rearwardly of the inlet opening to receive incoming pond water from the inlet opening so as to collect debris. A controllably positionable discharge assembly is provided in association with the skimmer construction so as to permit control of water levels in the skimmer.
