Where Did Mount Diablo Creek Go?

Streams on the north side of Mount Diablo (like Mitchel Creek) drain into Mount Diablo Creek and flow towards to Bay. Mount Diablo Creek once supported a healthy run of Steelhead. Those fish are now long gone. The Creek changed directions after oil, gas and water pipelines were laid across it in the floodplain near Clyde and an earthen berm built up. It now disappears into the marsh ground water instead of flowing in it's historic channel out to the Bay. We were out there with colleagues recently after the rains to see if it could be reconnected. We think it can be. Here are some photos that we took:
