<br /> <br />HUG16015-Parks, Trails, and Open Space DRAFT Chapter 15 <br />08/16/17 <br />Aquatic Communities <br />[Insert photo] Lake bed communities are found in shallow-water lakes. These communities are different from wetland habitats in that water is continuously present in <br />lake bed communities. Water is not always present throughout the year in wetlands. Lake beds usually have a cover of floating-leaved plants (waterlily), <br />submergent plants (pondweed) and free-floating plants (duckweed). <br />Many lake beds have been altered by dredging, filling, nutrients, sediments, and invasion by weeds. Aquatic communities, however, provide important <br />habitat for a variety of plant and animal species and are well worth protecting. <br />Hardwood Creek is listed as impaired for aquatic life, specifically, dissolved oxygen for the entire reach and biota for the lower reach. Peltier Lake and <br />Bald Eagle Lake are impaired for nutrients and mercury. Clearwater Creek is impaired for biota and Fish Lake is impaired for nutrients. <br />Prairie / Savanna <br /> <br />xxxx <br /> <br />
