Abstract

The submerged, floating, and emergent vascular flora of Lake East Okoboji, Dickenson County, Iowa, was surveyed by the senior author in the summer of 1961, with collections made at 21 stations. Emergent species and one hybrid, and 7 submerged or floating species were found. A comparison is made with a 1915 survey in which a very rich flora of about 18 emergents and 26 submerged or floating species was reported. Pollution by sewage and by agricultural fertilizers and other factors that may have caused changes in the vascular flora are discussed.
