In a remarkable display of environmental innovation, the California Department of Water Resources (DWR) has released compelling footage showcasing the activation of their cutting-edge bioacoustics bubble barrier. Installed above the confluence of the Sacramento and San Joaquin rivers at Georgiana Slough, the barrier employs underwater sounds, bubbles, and flashing lights to deter migrating Chinook salmon from entering the area.

The video, captured on a clear evening on November 30, 2023, provides a mesmerizing glimpse into the barrier's operation and its vital role in protecting the sensitive salmon population. Viewers witness the barrier's dynamic display of lights, illuminating the water's surface with vibrant hues as it works to safeguard the salmon from potential dangers lurking within the slough.
