Seventeen genera and 60 species of diatoms were identified from four different substrates in a warm spring-fed pond near Goshen, Utah. The diatom forms sampled included both plankton and periphyton. A minimum of 400 individuals were counted from each sample. Diversity and similarity indices were calculated, and substrate relationships were identified on their basis.
