Travel by canoe through a freshwater ecosystem teeming with aquatic life from duckweed and water lily to bass and beaver. Determine the primary productivity of this rich pond community through dissolved oxygen studies and investigate the pond's successional stage. Analyze collected data to identify natural and man-induced factors that lead to eutrophication of aquatic ecosystems.
