Every day throughout the Chesapeake Bay watershed, sediment from the ground is being washed or blown away by water and wind. This natural process is called erosion. When erosion happens too quickly—primarily due to water running off from agricultural land or excessive development in cities and towns—it can cause problems in waterways and the Bay. Too much sediment in the water makes the water cloudy, blocking sunlight from reaching underwater grasses. In addition, the excess dirt can potentially smother oysters. In this video, join CBF Educators Morgan and Kate at Maryland’s Calvert Cliffs as they explain why reducing erosion is good for the Bay.
