Like Kauneonga Lake, Swan Lake is part of the historic Borscht Belt, a mountain resort area immortalized in the 1987 film “Dirty Dancing.” In fact, the town’s name has nothing to do with swans — or with the famous ballet. Originally known as Stevensville, Swan Lake was renamed after Alden Swan, a businessman from Brooklyn who purchased the lake (and large tracts of land nearby) around the turn of the century. Today, fisherman like these waters for black bass, sunfish and pike.
