We have whittled down the choices for you on popular waters as well as some "under the radar" spots to enjoy some aqua therapy. The interaction of the two water masses of different salinities and densities in the estuary creates underwater turbulence and mixing that naturally flushes and energizes the coastal system. If water gets too warm, it can harm fish and aquatic life, influence undesirable changes in biological communities and increase the likelihood of algal blooms. When concentrations go below this level, sensitive organisms, such as some fish, may become stressed or die, especially if exposed to these conditions for prolonged periods. The phycocyanin measurement is used as a field screening for cyanobacteria and cyanobacteria blooms, also called blue green algae.
