Cyanobacteria Blooms in Upper Klamath Lake Lauren Senkyr ESR 575 Limnology November 23, 2009

Upper Klamath Lake Oregon’s largest lake Oregon’s largest lake: Volume ~ 536 x 1036 Surface area ~275 km2 Shallow, hypereutrophic Avg. depth 2.2 m Mean depth 2 m Max. depth 15.2 m

Management issues Water diversions ESA listed suckers Agriculture- nutrient inputs + water use Dams along Klamath River

Cycle of Water Quality Degradation in Upper Klamath Lake ↑ Algal Blooms ↑ Phosphorus ↑ pH ↑ Nutrient Loading ↑ Unionized Ammonia Fish Die-offs ↓ Dissolved Oxygen ↓ Algal Blooms

Cyanobacteria Aphanizomenon flos-aquae dominant June-October “Blue green algae” Aphanizomenon flos-aquae dominant June-October 1st appearance 1933 Collapse causes anoxic conditions that lead to fish kills Commercially harvested 1 toxic species in UKL (Microcystis aeruginosa)

Basic Biology of AFA Does not grow in pH < 7.1, water temperature < 11 degrees C Yamamoto and Nakahara, Limnology (2005)

Current Conditions in Upper Klamath Lake Favor AFA High pH High water temperatures Eilers et. al. 2004

Internal P Loading Internal load ~2/3 Total P in Upper Klamath Lake Decrease in total P in top 2 cm of sediment before/ after bloom (Simon et. al. 2009)

The Role of Wind Very strong relationship between climate and water quality in Upper Klamath Lake ↑ wind speeds = ↓ water column stability Wind induced mixing of sediments= increased nutrient availability (Kann and Welch 2005)

Impacts of altered hydrology Sedimentation Nutrient retention Greater internal loading Wind control accentuated by lower water levels Eilers. Et. al. 2004
