Lily Lake is a glacial lake on Pond Creek in Luzerne County, Pennsylvania, near Pond Hill in Slocum and Conyngham townships. Also called Long Pond or Beach Pond, it covers about 160 acres and is roughly a mile long. Though later managed as an impoundment, its form is fundamentally natural, and it is linked hydrologically to Cranberry Pond and Folstown Mud Pond. Much of its shoreline is publicly owned, and the lake is recognized on the Luzerne County Natural Areas Inventory. It also serves recreation, especially fishing and ice fishing, with stocked trout, surveyed fish populations, a boat launch, and regulated boating.
