The Lower Lake Powell system warrants more detailed analyses of the aquatic components analyses which will not only confirm the uniqueness of this desert impoundment but also serve as a base from which impact due to inevitable change can be assessed. It is hoped that this study will serve as a preliminary guide to the diatom components and stimulate further interest in the aquatic oasis of the Southwest. 120 pp.…
