   Crystal Lake is a small, shallow body of water measuring 5.5 acres.  It is located within a park containing both lawn and forest. 

   Emergent species dominated the northeastern and northwestern portions of the lake.  The middle of the lake was covered in dense stands of Nymphaea odorata and Utricularia vulgaris.  A large patch of Lemna minor was observed in the northwestern side of the lake, and smaller patches were found throughout the lake.  In the southeastern portion of the lake, including Utricularia vulgaris, Brasenia schreberi, Nymphaea odorata and Potamogeton pulcher, were found only along the shoreline.
