Environmental Impacts

The construction and operation of Strom Thurmond Dam have had significant environmental impacts on the Savannah River and its surrounding ecosystem. These impacts include alterations to water flow, habitat loss, and changes in sediment accumulation patterns.

Alterations to Water Flow

The dam’s primary function is to regulate water flow, creating a large reservoir that significantly alters the natural flow patterns of the Savannah River. This regulation has both positive and negative consequences for the river’s ecosystem.

• Increased Water Levels and Reduced Flow: The reservoir created by the dam significantly increases water levels upstream, reducing the natural flow of the river and altering the river’s flow regime. This can negatively impact aquatic species that rely on specific flow conditions for spawning, migration, and habitat.
• Reduced Water Temperature Fluctuations: The reservoir acts as a thermal buffer, reducing the seasonal temperature fluctuations that are important for many aquatic species. This can affect the timing of biological processes, such as fish spawning and insect emergence.
• Increased Water Clarity: The dam traps sediment, leading to increased water clarity in the reservoir. This can be beneficial for some species that prefer clear water, but it can also negatively impact species that rely on turbid water for shelter or food.

Habitat Loss

The construction of the dam and the creation of the reservoir resulted in the loss of significant riverine habitat, including floodplain forests, wetlands, and riparian areas. This habitat loss has impacted numerous plant and animal species, some of which are considered endangered or threatened.

• Floodplain Forests: The reservoir inundated extensive areas of floodplain forests, which are important for providing nesting and foraging habitat for numerous bird species, as well as habitat for amphibians, reptiles, and mammals.
• Wetlands: The dam altered the hydrological regime of the river, leading to the loss or degradation of wetlands, which are vital for water quality, wildlife habitat, and flood control.
• Riparian Areas: The reservoir submerged riparian areas, which are transition zones between the river and its surrounding terrestrial habitats, providing important habitat for a variety of species.

Sediment Accumulation

The dam traps sediment, preventing it from reaching downstream areas. This can have both positive and negative impacts on the river’s ecosystem.

• Reduced Sediment Supply: The reduction in sediment supply can lead to erosion downstream, as the riverbed is no longer replenished with sediment. This can impact the stability of the river channel and the habitats of benthic organisms.
• Nutrient Accumulation: The sediment trapped in the reservoir can contain nutrients, which can lead to eutrophication in the reservoir, causing algal blooms and oxygen depletion.
