A taxonomic study of the diatoms of the Goshen ponds and adjacent wet meadows, Utah County, Utah, was conducted from April 1974 to March 1975. The diatom flora of these warm spring fed ponds consisted of thirty-five genera containing one hundred twenty-one species, twenty-eight varieties, and two forms. The flora was dominated primarily by the following genera: Achnanthes, Fragilaria, Synedra, Navicula, Cymbella, Terpsinoe, and Nitzschia. Nineteen plates with 150 illustrations accompany the text.
