This tools allows you to visualize or download historical simulations and 2-week predictions of water quantity, nutrients and phytoplankton for Lake Okeechobee and surrounding rivers and canals.
The user interface displays individual monitoring stations (red shapes) for which the forecast and historical data are provided. Simply click on the selected station, and then a menu appears with multiple options to plot or download data for water, nutrients (phosphorus or nitrogen), or algae (chlorophyll-a).
Please take a look at the demonstration video (link).
Forecasted streamflow data are provided by the GEOGLOWS River Forecast System (RFS).
