The king made many such changes, but only four survive today, one of which is the Charles River which Charles named for himself.

The goal of the destratification project was to mix the extensive salt water wedge at the bottom of the river with the lighter fresh water at the surface to aerate the entire water . Higher water temperatures will increase the likelihood of algal blooms, which trigger increases in chlorophyll and phycocyanin measurements from the buoy. The Charles River runs for 80 miles from Hopkinton to Boston, Massachusetts. Tidal currents, which act independently of estuarine circulation, also add to the turbulence, mixing the salt and fresh waters to produce brackish water in the estuary. "Saltwater hugs the bottom of the river because it's heavier, denser than the freshwater. 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). 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.

A detailed depth chart of the lower basin of the Charles River, from near the Watertown Dam to the New Charles River Dam, has been created by a partnership between the MIT Sea Grant College Program and the Charles River Alliance of Boaters (CRAB). Temperature reduces the levels of dissolved oxygen since warmer water cannot dissolve as much oxygen as colder water.
