When suspended mud and solids from a river enter the estuary, they encounter the salt front. The Charles River is the most prominent urban river in New England. Power plants' discharges are regulated to have minimum impact on fish and other organisms. When too many nutrients enter the water, algae and cyanobacteria concentrations can take off and form "blooms". During low flow summer conditions the saltwater wedge expands up the river. The vigor of the circulation depends in part on the supply of river water to push the salt water back. Potomac River*: Rt.

The following parks have access to bank fishing. Several factors can affect the concentration of dissolved oxygen: Turbidity is one of the ways to determine water clarity by measuring of how much suspended material is in the water. 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. [32] Overall boatability and swimability of 82% and 54% in 2011 compare with 39% and 19% in 1995.
