Other than two new siphons that <br />were financed by the CWCB in 2002, the system has not had significant upgrades since the canal <br />was constructed nearly 125 years ago. In order to best manage and deliver its water, the Company <br />is planning on the following phased improvements: <br />• Phase 1: Repair the river diversion dike, repair the ditch where there are seepage problems, install <br />and/or replace headgates and flumes, and begin phreatophyte removal. <br />• Phase 2: Add a trash rack to the siphon, install and/or replace additional headgates and flumes that <br />were not completed in phase 1, install supervisory control and data acquisition (SCADA) <br />monitonng equipment. <br />• Phase 3: I�lstall additional SCADA monitoring equipment. <br />Table 2 shows the estimated costs of all of the prioritized capital improvements that have been <br />identified for each phase this Project. All of these improvements are expected to be completed <br />between the winter of 2009 and the spring of 2012. <br />
