A 19-ha Colorado montane reservoir was kept thermally destratified by continuous aeration for 1 yr. Total phytoplankton abundance was reduced, but phyla varied in their response. Green phytoplankton (Chlorophyta) decreased in abundance and diatoms (Bacillariophyacea) were nearly eliminated during destratification. Blue-green algae (Cyanophyta), however, increased in abundance and this phenomenon may limit the use of destratification in water management. Vertical distribution of phytoplankton was not affected by destratification.
