LANDER, Wyo. — That old Christmas tree may still be good for something after all.

Officials in Fremont County are collecting used Christmas trees to drop into Ocean Lake to improve fish habitat.

KOVE in Lander reports that the Fremont County Solid Waste Disposal District is encouraging people to recycle their clean used trees at collection sites in Lander and Riverton.

The trees will be dropped through holes in the ice at designated locations at Ocean Lake in late January. Officials say they provide good habitat for the fish.
