Grinnell Lake, Lake Josephine, and Swiftcurrent Lake, at an elevation of approximately 5,000 feet in northwestern Montana, are comparable with lakes in the montane zone defined by Pennak for lakes at elevations between 8,200 feet and 10,500 feet in the Rocky Mountains of northern Colorado. Five species of Copepoda, six Cladocera, and four Ostracoda were collected in the lakes studied. The population of microcrustacea in these lakes was most dense in or slightly above the masses of rooted aquatic vegetation growing to a height of six to 10 inches above the bottom wherever the water was between three feet and …
