When water slows down, such as when it flows from a creek into a lake, suspended sediment can drop out of suspension and settle on the lake bed.

Lake Accotink is a 55 acre lake in Fairfax county which suffers from high rates of sedimentation. As the lake fills with sediment, it loses volume. This animations shows how the lake might continue to lose volume over time if dredging does not continue.

Lake Accotink is a 55 acre lake in Fairfax county which suffers from high rates of sedimentation. The lake is fed by Accotink Creek, which includes the Long Branch tributary. These two streams deliver most of the sediment to Lake Accotink.

Water levels in a fractured rock aquifer fluctuate as seismic waves move past.

Groundwater Response to Seismic Waves

Earthquakes can sometimes cause rapid changes in water levels. As seismic waves travel through rock formations, they can squeeze and stretch the rocks. This deformation can cause groundwater levels in aquifers to rise and fall, and it can rapidly force water in and out of nearby wells.

Accotink Creek is an urban stream in Fairfax County, Virginia. Like many urban streams, its banks are heavily eroded, and that eroded sediment is transported downstream. This impacts downstream water quality and contributes to lake sedimentation in Lake Accotink.

Accotink Creek is an urban creek and a tributary of Lake Accotink. Accotink Creek suffers from high rates of streambank erosion, which causes the steep, unstable banks seen on the far side of the creek in the above image.
