Biofouling protection of elevated volume/velocity flows

A device for reducing biofouling in a water system, the device comprising:

• a contained water feature positioned within an open water environment, wherein the contained water feature comprises one or more permeable or nonpermeable walls separating a volume of water from the open water environment so as to form contained water within the contained water feature;
• and
• one or more structures positioned in the contained water within the contained water feature, wherein each of the one or more structures defines a shape;
• wherein the each of the one or more structures includes biocide thereon or therein that contacts the contained water in the contained water feature to aid in forming conditioned water within the contained water feature,
• wherein at least some of the conditioned water from the contained water feature is provided to the water system for use therein, the conditioned water staying within the contained water feature for a dwell time prior to entering the water system.
