A near 10-year project aimed at improving the environment and water quality at Possum Kingdom Lake came to a positive conclusion in 2015 thanks to the cooperation of hundreds of lakeside dock owners. Concerns for fish and wildlife as well as water quality at the reservoir prompted the Brazos River Authority Board of Directors to pass a resolution in 2006 to phase out the use of non-encapsulated foam flot\ation on docks.  At the end of the decade-long timeframe, 99 percent of all commercial and residential docks at PK have been converted by their owner’s, eliminating the buildup of floating foam trash and residue that was negatively impacting fish and wildlife habitat on the lake.

Along with typical trash and debris, non-encapsulated foam used on floating docks deteriorates, breaking loose and creating an artificial snow-style buildup on the water, in coves, and along shorelines, reducing the service life of floating docks and creating an eyesore on the lake

However, most importantly, small pieces of loose foam are an environmental concern.  As the foam breaks into tiny pieces, it can be mistaken for food and consumed by fish, birds, and other wildlife, thus negatively impacting their environment and potentially degrading their health.

The resolution requiring replacement of non-encapsulated foam was passed in 2006 with the adoption of the PK Shoreline Management Plan.  At that time, the BRA Board set a deadline of January 1, 2015 for all PK lakeside docks and commercial marinas to convert to encapsulated foam. This requirement was reaffirmed in a subsequent resolution passed by the Board in October 2014.  Since that time, dock regulations for all BRA reservoirs state that all dock flotation must be encapsulated with a rustproof, non-corrosive, UV resistant shell.  

Encapsulated foam replacement is a great way to help keep the water cleaner and promote healthy marine habitat. The Brazos River Authority works continuously to maintain the health of our reservoirs, working with lakeside property owners to ensure the health and safety on the lakes.
