If you’re a steelhead trout wanting to start a family, it’s a long swim from San Francisco Bay to the sheltered breeding grounds of Alameda Creek. But now, for the first time in nearly three decades, that winding 40-mile path from Union City to the rolling foothills of Sunol is finally flowing free. “The flows get really high here,” says California Trout Regional Director Claire Buchanan, pointing to the running creek. The environmental group helped push through the final removal of a structural barrier allowing migrating fish to reach the shaded banks.
