Tempe Towne Lake is a water body created by inflatable bladder dams that were constructed along the highly regulated and formerly-perennial Salt River in Phoenix, Arizona. The dam ruptured on 20 July 2010, exposing organic and clay-dominated lake bedsediments that had been submersed for approximately 10 years. A riverine marshland developed on the wet sediments, and during a site visit on 27 Sept 2010 twenty taxa were collected (Table 1). Below is a discussion of 3 species of interest.
