Giant Salvinia Barrier

In 2008, CLI supported the efforts of the Greater Caddo Lake Association, Cypress Valley Navigation District and others to construct an experimental barrier and implement a collection program at Caddo Lake.  The barrier was constructed for 2 miles across the lake by volunteers who then collected the giant salvinia that was trapped by the barrier daily.  During a storm in 2009, the barrier was damaged and, by then, giant salvinia had begun to be widespread in the lake.  It was, therefore, removed rather than repaired.
