Lakes of the Southern Mountains Professional Review and Guide
"Each lake has its own particular characteristics, and each has certain species that are more likely to be found. Lake Julian is about a mile long and about 0.3 to 0.5 mile wide. Compared with other lakes in the area, Lake Julian is much deeper and much warmer in winter (it never freezes over), since it is used as coolant for a coal-fired power plant. In fact, in winter it is best to bird this area in the afternoon because thick fog frequently shrouds the lake in the morning. Lake Junaluska, which is about the same size as Lake Julian, is mostly shallow.
Lake Osceola is about 0.5 mile long and 0.1 mile wide. Lake Osceola is the smallest and the shallowest of the three lakes, with weeds at the surface in about a third of the lake. Nearby Four Seasons Marsh is not a lake but a weedy marsh that is about 0.3 mile long and 0.1 mile wide. Habitats: Weedy marsh and three small to medium-size lakes surrounded by residential areas, parks, industry, and a conference center. Key birds: Winter: Horned Grebe; Hooded and Red-breasted Merganser; Greater Scaup. Migration: White Ibis; Snowy Egret; Little Blue Heron."
