Lake Christina Barrier
Constructed: 1991
Classification: Lake
Smith-Root constructed a concrete culvert to include a barrier for exclusion of invasive species.
This turn-key project included the design and construction of a 10 foot x 5 foot rectangular concrete culvert. Seven steel flat bar U-shaped bolted electrodes are located three feet apart in slots in the Insulcrete™ walls and base slab.
Steel gates at each end provide security. At the downstream end, an additional fish gate automatically drops down in the event of a power loss. Electronics are housed in a nearby small building.
