RD 2.122, located northeast of the City of Pittsburg, is 428 acres in size. The property is only accessible by boat, and there is no ferry service to the island. The sole landowner, Winter Islands Farms, operates a private duck hunting club on the island. There is no permanent residential population on the island, no anticipated development, and no growth anticipated for the foreseeable future. The District employs no full-time or part-time staff positions. Maintenance of levees and flood control facilities are completed on an as needed basis and no regular assessments are collected or budgeted. RD 2122 maintains five miles of levees. The District reports that 1.5 miles of levees meet the HMP standard, and the remaining 3.5 miles of levees do not meet the HMP standard.

In June 2012, the District approved a Five Year Plan to support future planning efforts by the District and the DWR. The District's goal is to complete all rehabilitation work on the levees to meet the HMP levees standard within five years. Engineering, planning, mitigation and construction are expected to cost approximately $4.482 million, according to the District's Plan. For purposes of the Plan, the District assumes that funding will be available under the Special Projects Program and the Subventions Program over the five-year period.
