Delta, Carquinez Strait and San Pablo Bay. This storm water can pass from small open creeks to large underground tunnels; from narrow rocky stream beds to wide concrete channels; all the while gathering debris, speed, volume and power. At key points along the way, large structures have been built into the system to slow down the water and control the power. This allows the water to flow back into wide earthen channels without destroying their natural habitat or causing erosion. These structures are an efficient tool in managing our floodwaters but can be deadly for humans.
Please talk to your children and friends about the flood control channels. Appreciate the great job they do for our community, but leave the channels to storm water and Stay Out, Stay Alive!
