Floodplains are extremely productive habitats for native fish and birds, yet floodplains in California are cut off from rivers by levees and development. … Recognizing these constraints, reconciliation ecology encourages land and water managers to re-engineer human-dominated landscapes to be more hospitable for native species without significantly diminishing human uses. California’s Yolo Bypass, an engineered floodplain on the Sacramento River, is an excellent case study of this new approach to native species conservation.

Floodplains in California

With the dual threats of obsolete levees and anticipated rising sea levels, floodplains—low areas adjacent to waterways that flood during wet years—are increasingly at the forefront of many public policy and water issues in California.

Adding to the challenges, many floodplains have been heavily developed and are home to major cities such as Sacramento. Large parts of California’s valleys are historic floodplains as well.

Sacramento-San Joaquin Delta Levees

Sacramento-San Joaquin Delta Levees

With the Sacramento-San Joaquin Delta crucial to California’s overall water supply, roughly 1,115 miles of levees protect farms, cities, schools and people.

Since the 19th century, levees—from the French word ‘lever’, or ‘to raise’— have been erected to protect “reclaimed” marshland, popularly referred to as Delta islands. The levees were built to prevent flooding and allow cultivation of the rich soil while protecting public infrastructure such as highways and pipelines.
