Sediment

  • How does sediment affect the Bay?

    Sediment is made up of loose particles of sand, silt and clay. It is a natural part of the Chesapeake Bay, created by the weathering of rocks and soil. In excess amounts, sediment can cloud the waters of the Bay and its tributaries, blocking sunlight for underwater grasses, covering bottom habitats (such as oyster beds) as it settles and reducing water quality for fish and other aquatic species.

  • 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.
