It does not take long before you arrive at the place that the stream empties out into a serene lake. In the middle of the lake is a tiny, forested isle where a small palace of white stone stands. The water is crystal clear, showing the lake's gravel bottom. Schools of multicolored minnows swim below the surface, mirroring the iridescent dragonflies darting through the air above. In the deeper part of the lake, a group of young otters frolic, rising, submerging, and playing without care. A little way down the shoreline, a wide, flat-bottomed raft rests on the water next to a small wooden dock. A long pole,for guiding the vessel across the water, lies beside the raft.
