The increase in temperatures and decreasing water levels in bodies of water are setting the stage for an increase in algal growth within our waterways. Littoral (nearshore) algal blooms are already visible, and Cyanobacteria (blue-green) algal blooms have recently closed down beaches in Lake Champlain.
Algae, the base of the aquatic food web is important to our aquatic ecosystems. They provide food for many organisms and create oxygen and shelter. Algae remove nutrients directly from the water column. If excessive nutrients enter our waterways, the nearshore algae will respond by blooming. The more nutrients that enter, the more algal growth there will be. Generally 1 pound of phosphorus will grow 500 pounds of wet algae. Phosphorus is not the only nutrient needed, nitrogen and carbon are needed to cause a bloom. » Continue Reading.
