Abstract
The seasonal successions of phytoplankton in Onondaga Lake during 1975-77 were generally similar to the 1973-74 period immediately after the reduction in P entering the lake. Diatoms and flagellates were dominant in spring and replaced in importance by chlorococcalean green algae and the diatom Cyclotella glomerata during summer. A die-off of summer algae was observed in 1977. During the summer, silica was depleted in the epilimnion by diatom growths and P by chlorococcalean green algae. Enrichment studies indicated that availability of P to green algae and silica to diatoms may have contributed to determining their periods of dominance. Blue-green algae continued to be relatively unimportant in the plankton, in contrast to the conditions before 1972 when they caused late summer blooms.
