Estero River Water Quality

DO = Disolved Oxygen, you want 4 or more for good fishing.
Salinity in the Gulf is around 37-38. distilled water is 0. (your well can be around 1 in the the dry season).
Nitro = Nitrates from fertilizer. Florida Nutrient Plan Goal 0.52
Phos = Phosphates, some is natural, some from soap and some from fertilizer. EPA recomendation <0.05
             The goal in the Florida Nutrient Plan is .04
Chl = Chlorophyll, an indicator of algea EPA has not developed a standard I can find.
Colif = Fecal Coliform. 0-199 Good, 200-399 moderate, >400 bad ... they close beaches.
