Dredging is not that costly or difficult, but finding a place to put contaminated sediments is a problem. 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. EPA scientists and water quality managers use the data from this buoy to assess water quality conditions and to help track cyanobacteria (blue-green algae) blooms. [35], Starting in 2007,[36] the Charles River Swimming Club has organized an annual race for its members, but obtains a special permit and must monitor water quality and rainfall in the days leading up to the race.

Our mission is to explore and understand the ocean and to educate scientists, students, decision-makers, and the public. Here in south Louisiana it's causing a unique phenomenon, changing the point at which the freshwater river and salty sea meet. For example, sea water will have higher specific conductance and distilled water will have lower specific conductance. When the locks Research showed that these shad were in fact returning to the river to spawn, a testament to the improved health of the river. Are warming Alaskan Arctic waters a new toxic algal hotspot. Because stormwater flushes dirt and other surface pollutants into the River, higher turbidity readings can occur. [42] The diadromous fish (fish that spend parts of their lives in fresh and salt water) that can be found in the Charles are mostly anadromous species (fish that migrate from sea to freshwater to spawn). Jump to content. Unlike fresh water, which rides up and over the saline layer, the sediment falls out of the surface layer into the denser, saltier layer of water moving into the estuary. 360 Bridge. [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. "Saltwater hugs the bottom of the river because it's heavier, denser than the freshwater. Rivers make up 0.49% of surface freshwater. Let's just say, it scared the out of me.

The State of Massachusetts has established protective water quality standards for Class B waters (such as the Charles or Mystic Rivers). These areas are important in preventing downstream flooding and providing natural habitats to native species. "[22] Fish kills and submerged vehicles were a common sight, along with toxic chemical plumes that colored parts of the river pink and orange.
