Farmers and ecologists are partnering to restore the state’s natural flooding patterns, allowing native fish to thrive.

Until just a couple of centuries ago, inland California was a lush tapestry of wetlands and floodplains that nourished a thriving ecosystem of fish. But as the state — and its vast agriculture industry — has grown, its waterways have been modified drastically. Rivers have been drained, fields dried out, levees and dams constructed. These engineering feats, coupled with extreme drought, have decimated natural habitats. Today, a shocking 83 percent of native fish species in the state are in decline.
