How is fresh water brought into the Chesapeake Bay?

Fresh water enters the Chesapeake Bay primarily from its rivers and streams. Fresh water also enters via rain, snow and groundwater.

What causes poor water clarity?

Nutrient and sediment pollution are the main causes of the Chesapeake Bay’s poor water clarity. Nutrients fuel the growth of water-clouding algae blooms, while particles of sediment can float in the water. Weather also plays a role in water clarity: rain storms wash dirt and pollutants into the Bay, muddying the water.
