White Lake Barrier
Constructed: 2010
Classification: Lake
Smith-Root pulsators drive a small barrier retrofitted into a round culvert to stop invasive carp from reentering a restored lake.
This barrier was commissioned by Shell Rock River Watershed District to protect White Lake from re-infestation by invasive asian carp.
The barrier is inside a 84-inch ID GRP pipe culvert. There are six 3/16 inch x 3 inch circular electrodes spaced 30 inches apart: three pulsators operate on the four inside electrodes
while the outer electrodes act as parasitic electrodes to reshape the field. Steel gates at each end provide security. Electronics are housed in a nearby small building.
