This pumping action leads to some of the highest growth rates of microscopic plants (researchers call it primary production) in any marine environment. 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. Despite the river's length and relatively large drainage area (308 square miles, 798km2), its source is only 26 miles (42km) from its mouth, and the river drops only 350 feet (107m) from source to sea. 1.
