Turbity and Sedimentation
Habitats Affected: Water column, shell bottom, SAV, soft bottom, ocean hard bottom
Common Sources: Construction sites, runoff from agriculture, forestry, roads, mining, resuspension from dredging, and bottom-disturbing fishing activities
- Elevated turbidity impacts the ability of SAV plants to survive and grow.
- Suspended sediment in the water column can clog fish gills, deter successful recruitment of invertebrates onto shell bottom or ocean hard bottom, reduce feeding success of visually oriented predators.
- Excess sedimentation can cover shell bottom and ocean hard bottom, and fill in shallow creeks and rivers.
- Suspended sediments transport bacteria and toxins through coastal waters, making them available to aquatic organisms in the water column.
