Purchase Back Issues The records track 31 freshwater species, 59 saltwater species and 17 spearfishing categories. Higher water temperatures will increase the likelihood of algal blooms, which trigger increases in chlorophyll and phycocyanin measurements from the buoy. The landward intrusion of salt is carefully monitored by engineers because of the potential consequences to water supplies if the salt intrusion extends too far. This will increase the amount of suspended (neither sinking nor floating) material in the Charles and can increase the measurement of turbidity.

Starting at the Watertown Dam, the Basin is a 476-acre section of the Charles that is dotted . High pH readings can occur during algae blooms due to chemical processes associated with photosynthesis. Lower pH readings are sometimes seen in fresher waters due to acid precipitation or even naturally-occurring organic acids, which can be found in bogs and some wetlands.

Algae and other aquatic plants also have an effect on dissolved oxygen. Turbidity is measured in Formazin Nephelometric Units (FNUs). This teeming population of plankton provides a base for diverse and valuable food webs, fueling the growth of some of our most prized fish, birds, and mammalssalmon, striped bass, great blue heron, bald eagles, seals, and otters, to name a few.
