"Turbidity barrier" protects lake fish from excessive sediment

When South Carolina Department of Transportation work crews expanded Lake Murray in Lexington County by replacing a causeway with a bridge, they stretched floating and weighted turbidity barriers across the lake on both sides of the construction, leaving space at the bottom for fish to pass underneath. Most of the suspended sediment was trapped by this thick "curtain" and deposited on a small area of the lake bottom. Thanks to the simple device, Lake Murray's bream, crappie, and famed striped bass were protected from potentially damaging sedimentation.
