Mud Lake Barrier
Constructed: 2009
Classification: Lake
Smith-Root pulsators drive a small barrier retrofitted into two round culverts to stop invasive carp from reentering a restored lake.
These barriers were commissioned by Shell Rock River Watershed District to protect Mud Lake from reinfestation by invasive asian carp.
The barriers are inside 54-inch diameter Hi-Q pipe culverts. 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 culvert end provide security. Electronics are housed in a small building nearby.
