Lagerman Reservoir: A Look Into The Future of Cyanobacterial Freshwater Algal Blooms Public Deposited
- Abstract
Lagerman Reservoir is a saline, closed evaporite basin subject to changing hydrologic regime, algal blooms, and fish kills. This ecological survey was conducted to obtain scientific data for future management decisions and recreational safety. Weekly shore samples and monthly depth profile samples were taken, along with data synthesis of EPA’s CyAN satellite monitoring system. Dissolved oxygen was low, indicating unfavorable conditions for fish and macroinvertebrates. Transparency and nutrient concentrations were also low, with nitrogen limiting the system. The algal biomass was dominated by Synechococcus, as well as Dolichospermum, Lyngbya, Oscillatoria, and Merismopedia. Chlorophyll-a analysis indicated similar trends to the CyAN satellite data, with a peak of algal growth around late June, followed by a die off of algal biomass. This reservoir ranged from eutrophic to hypereutrophic. Lagerman Reservoir is considered to be unsuitable for fish and vulnerable to toxic algal blooms that could be hazardous to human health.
