LIFE HISTORY IN WOLF LAKE STUDY AREA Wolf Lake is a long (ca. L9 km), narrow (ca. km), and ancient ox- bow of the Big Mudily River (Missis- sippi drainage) situated .south of the LaRue-Pine Hills Ecological Area to which it is connected by bottomland swamp. The lake is apparently still in a fairly natural, undisturbed condition and is estimated to be at least 2,00(1 years old (E. Donald McKay IIL per- sonal communication) . The northern portion of the lake was recently ac- quired by the U. S. Forest Service, whereas the southern portion of the lake is privately owned by the Trojan HABITAT Wolf Lake is characterized by tvro predominant habitats: a heavily veg- etated shoreline with many submerged logs and stumps (Fig. 5) and an open deepwater area in the center of the lake free from vegetation and submerged ob- jects. The lake is not shaded and the water is usually turbid. The vegetated shoreline, where L. symmctricus occurs (Fig. 5), is dominated by spatterdock [Nymphaea advcna), American lotus (Nclumbo hitea) , common arrowhead (Sngillaria latifolia) , coontail (Cera- tophyllum dcmersum) and duckweed {Lcmna spp., Wolffia spp.) . The bot- tom consists mostly of decomposed veg-. Fig. 5—Vegetated margin of Wolf Lake, Union County, Illinois, illustrating the preferred habitat of Lepomis symmetricus.
