A qualitative evaluation of the terrestrial aquatic biological resources within the Meredosia, Illinois Meredosia Willow Creek and Coon run Drainage and Levee District in Scott and Morgan Counties, Illinois was performed during May and June of 1982. Quantitative sampling was conducted to support qualitative observations. Wildlife habitat is generally limited to the western half of the study area. The dry, sandy soils were observed to support flora and fauna typical of that in the Illinois River Sands Area Natural Division. Smith Lake and lower Coon Run and Willow Creeks were found to have the most productive fishery in the study area. Because no riverfront levee is present, there is a greater exchange between internal fish populations and those of the Illinois River. During low flows, movement is confined to available drainageways connected to the Illinois River. More extensive movement e.g. into Smith Lake occurs during flood events. Author
