Suspended materials can include soil particles (clay, silt, and sand), algae, plankton, microbes, and other substances. [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. Specific conductance measurements are affected by the presence of dissolved solids such as salts. We will develop better policies only if we can ground them in better science.

During low flow summer conditions the saltwater wedge expands up the river. You cant see these swirling waters from the surface, but a fisherman may find that his net takes on a life of its own when he lowers it into seemingly placid water. The diversity and the high energy of the ecosystem make estuaries remarkably resilient. These dams sometimes allow some saltwater to enter during high tides, lower river flows and during boat locking which can increase salt levels and thus specific conductance. fresh water Water is not to exceed 28.3C (83F).
