The CyanoFluor device the Lake Anna Civic Association recently purchased to test for the presence of cyanobacteria. Both types can create algal blooms, the rapid growth and build up of phytoplankton in an environment. The assessment focused on an 865-acre area of Lake Anna in the upper North Anna River branch (see Figure 1). Since then, it has caused fish kills in five major river systems and over 25 lakes or reservoirs in Texas. Do not move water, aquatic wildlife or plants (fish, frogs, tadpoles, clams, crayfish, aquatic weeds, etc.) LACAs decision to focus on near-term mitigation approaches was developed over several years of research and data analysis. Sometimes algae rapidly grow out of control, or bloom. Note: Although ponds and lakes smaller than a few hundred surface acres can be treated successfully, these treatments may not be economical or feasible in the larger and more complex reservoirs and rivers. Based on the results of the LAAC assessment, major federal, state, and local funding is needed to get long-term results from watershed management. It has been found in Saguaro Lake, Canyon Lake and Apache Lake. LACA recently approved the purchase of devices that can assist in detecting the presence of cyanobacteria and algae and give preliminary warnings of potential toxins in the water column. The Virginia Department of Health is asking people to avoid swimming in or contact with waters on the western side of Lake Anna and its tributaries due to the presence of a harmful algae bloom.
