About Jersey Island
Jersey Island is owned and operated by Ironhouse Sanitary District. The island is located between Oakley and Bethel Island on the San Joaquin River. Ironhouse's recycled water is sent to Jersey Island to 450 acres of irrigated field that grows 2,000 tons of hay per year.
Part of the hay is fed to approximately 2,200 head of cattle owned by Ironhouse. The rest is sold to feed lots in the Central Valley and local ranches. Ironhouse leases property on Jersey Island for natural gas wells.
Reclamation District 830 is responsible for maintenance and levee restoration on Jersey Island.
