Paderewski Park Pond is 16 acres and located within a municipal park. It is surrounded by an area that is completely developed for residential use. A native waterweed (western waterweed, Elodea nuttallii) grew extremely abundantly at the time of our August 2005 survey. The plant grew without interruption from one shore to the other and from the bottom to the surface. It formed dense mats in several areas in water up to seven feet (2 m) deep. All other plants were much less abundant. Small pondweed (Potamogeton pusillus) was observed as isolated plants growing with western waterweed in deep water. It also occurred in a number of patches, primarily in shallow water along the southwest corner of the pond and in a sandy area west of an island. The native large-leaf pondweed (Potamogeton amplifolius) and the invasive annual minor naiad (Najas minor) also were recorded in this area of the pond. The native slender naiad (Najas flexilis) was observed in several patches widely scattered around the pond. Invasive Eurasian watermilfoil (Myriophyllum spicatum) was recorded in several small patches, primarily along the southern shore and in the northwest corner of the pond.
