Secchi depth model to forecast freshwater algal and cyanobacterial blooms

How to use the model

Input Secchi depth (meters) in the first white box below.  This value will be used to calculate the predicted concentrations of algae, cyanobacteria, or toxic cyanobacteria and associated risk level for your waterbody.  Note that "risk" is a relative term.  We used our knowledge of our dataset to relate risk with certain water quality parameters.  If you are concerned about your waterbody, we encourage you to contact a local USDA extension agent

Important note about the Secchi depth model

Please keep in mind that these models will be most relevant to systems sampled during warm summer months.  Also, since Secchi depth is influenced by organic (phytoplankton) and inorganic (suspended sediment) particles, Secchi depths collected after rain events may provide spurious predictions.
