This will increase the amount of suspended (neither sinking nor floating) material in the Charles and can increase the measurement of turbidity. The phycocyanin measurement is used as a field screening for cyanobacteria and cyanobacteria blooms, also called blue green algae. [11], Duck Boats regularly enter the Charles near the Museum of Science and river tour boat excursions depart from a lagoon near the Museum. Suspended materials can clog fish gills, reducing resistance to disease in fish, lowering growth rates, and affecting egg and larval development. I don't quite know if there really is a definate line for salt/brackish being as how both the Chick and James are affected by the tide coming of the bay/ocean.

Freshwater is called fresh because its placement in the water cycle removes sediment, salt, and toxins. This designed landscape includes over 20 parks and natural areas along 19 miles (31km) of shoreline, from the New Dam at the Charlestown Bridge to the dam near Watertown Square. Carp and bass are caught in that part of the river, so it's closer to fresh than salt as far as fish are concerned. CSOs occur when the sewer system is overloaded and wastewater is carried through the stormwater pipes and discharged into the River. I just looked at some numbers. With a better understanding of these systems, we can reverse their decline and restore the ecological richness of these valuable, albeit muddy, environments. Let's just say, it scared the out of me.

When river water meets sea water, the lighter fresh water rises up and over the denser salt water. This means that a specific volume of salt water is heaver than the same volume of freshwater. Since pH can be affected by chemicals in the water, pH is an important indicator of water that is changing chemically. High pH readings can occur during algae blooms due to chemical processes associated with photosynthesis. [7], The Charles is renowned as a rowing and sculling locale, with many boathouses and the three-mile Head of the Charles Regatta, the world's largest long-distance rowing regatta.

The tide has just turned, and a tongue of salt water is first creeping, then galloping, back into the Fraser just a few hours after being expelled by a strong outflow during the previous ebb. New policies about land use, water diversion, and even global carbon dioxide production (which affects global warming and sea level rise) will be needed to protect these vulnerable estuarine environments and their human inhabitants.
