The U.S. Army Corps of Engineers at Carlyle Lake will be collecting used Christmas trees for the annual Christmas tree recycling project.  These trees will provide an effective and economical means of providing fish habitat at Carlyle Lake.  Each year, volunteers from various organizations, clubs and other citizens donate their time to help submerge the trees in the lake to provide fish shelters, which provide fish with breeding areas, resting places and protection.  This helps the fish grow large as well as the population increase.  Trees can be dropped off now through January 20, 2014 at these locations:  Plant Land on Old Route 50 east of Breese, the Olympic Shelter parking lot in Eldon Hazlet State Park and the Little Prairie Nature Trail parking lot, located in the West Spillway at Carlyle Lake.  For more information on dropping off trees or to volunteer, call the Carlyle Lake Project Office at 618-594-2484.
