The U.S. Army Corps of Engineers at Mark Twain Lake encourages local citizens to participate in the eighth annual Christmas tree recycling program. Christmas trees can be brought to a collection site at John Spalding Boat Ramp. Christmas trees will be accepted at this location until January 31, 2013. Residents of the Mark Twain Lake surrounding area can contribute to these efforts by donating their trees. The trees will be bundled together and sunk in Mark Twain Lake, creating underwater fish structures. Artificial or flocked trees (with artificial snow) cannot be accepted. Remove all tinsel, decorations, stands and plastic bags from the tree. Individuals or fishing /outdoor organizations are encouraged to help place the trees in the designated locations. Anyone wishing to volunteer or wanting more information should contact Brad Stamp at the Mark Twain Lake Project Office at (573) 735-4097.
