Twitchell Island, River delta island near Sacramento, United States.
Twitchell Island spans 3,000 acres in the Sacramento-San Joaquin River Delta, located 22 miles southwest of Sacramento at 6.6 feet below sea level.
During the 1870s, farmers constructed dikes, drained marshes, and burned tules to establish agricultural operations on the island's peat-rich soil.
The island maintains experimental agricultural practices focused on tule and cattail cultivation to prevent soil degradation while supporting local farming traditions.
The State of California owns 85 percent of Twitchell Island, with access managed by Reclamation District 1601 under specific environmental regulations.
Since 1996, scientists conduct research on the island to determine if tule and cattail growth can reverse soil loss and capture carbon dioxide.
