Lower Tubbs Island is a tidal marsh near Midshipman Point in northern San Pablo Bay, California, and is part of the San Pablo Bay National Wildlife Refuge. Historically, Tubbs Island was used as a club for duck hunters, protected by levees that could be opened with the tides to release salt water into the sloughs. In 1969, it was purchased by the Natu

After 100 years of restricted tidal activity to support agricultural use and salt harvesting, the tidal marshes around San Francisco Bay, like this one at Bair Island, are steadily rebuilding, returning to a stunning mosaic of marsh, mudflat, and channels.
