Water clarity improves when less pollution washes off the land and into streams, rivers and the Chesapeake Bay. You can help improve water clarity by fertilizing your lawn less and planting a buffer of trees and shrubs around your property. Also, when boating, make sure you obey wake laws so you don’t stir up bottom sediments in shallow areas.
Poor water clarity is usually caused by a combination of suspended sediments, organic matter and excess nutrients that fuel the growth of water-clouding algae. Weather also plays a large role in water clarity. Rain storms can wash dirt and pollutants into the Bay and cause the water to look muddy. During drier conditions, the water is usually clearer.
