During the next few years, as the river adjusts to the channel improvements, minor corrective work may be required. No Name Lake is a backwater area located in the Parker II Division. Approximately 1,200,000 cubic yards of material are to be excavated and placed in the designated areas to restore the Lake to pre-1983 conditions. This is a portion of the mitigation for the Parker II Channel Modification Project. Other potential marsh and aquatic enhancement in this division includes the rehabilitation of the Deer Island complex, a large lake and marsh in the Parker I area. Palo Verde Division The division begins at the Palo Verde Diversion Dam and extends to Taylor Ferry near the Imperial County, California line. Channel stabilization and other improvements are essentially complete in the Palo Verde Division and work primarily consists of routine maintenance and repair to structures. Previous work in this area consisted of earthfill training structures and bank protective riprap designed to prevent random meandering. C-8 Backwater is located in the Palo Verde Division south of Blythe. It is a mitigation feature which Reclamation maintains. Rehabilitation work was begun in C-8 but was suspended early in 1995 due to lack of funding. It is currently planned to complete C-8 after the work in No Name Lake. Approximately 10 months of work still remains. Cibola Division The Cibola Division extends 19 miles from the lower end of the Palo Verde Division to Adobe Ruin, near Walter's Camp. Through much of the Cibola Division, the natural channel was shallow due to sediment deposition. A program to correct channel deficiencies by dredging and constructing levees was initiated in 1964 and completed in 1970. The old river channel was essentially abandoned and became a part of the Palo Verde outfall drain. The river channel in this division is totally stabilized through the use of dredging, bankline riprap, training structures and jetties. Three Finger Lake is a decadent wetland located on the old river channel and within the Cibola National Wildlife Refuge south of Blythe, California. Approximately 800,000 cubic yards of material have been excavated and placed adjacent to the design lake configuration to restore the lake to its historic conditions. This is a cost-shared effort with FWS. Imperial Division The waters behind Imperial Dam, including associated backwater areas constitute the Imperial Division. The division extends through the reach from the lower Cibola Valley, to Appendix C - 7
