Eastern San Joaquin Groundwater Basin Groundwater Management Plan Northeastern San Joaquin County Section 8 Groundwater Banking Authority 120 Integrated Conjunctive Use Program the Reservoir to Bellota would be re-diverted to the SEWD water Treatment Plant, Mormon Slough, Potter Creek, Mosher Slough, the Lower Calaveras River, and potentially the proposed Alliance Canal for beneficial use or direct groundwater recharge. Evaporation is potentially a major concern for shallow large surface area reservoirs; however, the operation of the proposed Duck Creek Reservoir would completely drain Duck Creek Reservoir to maximize use in anticipation for the next season’s divertible flows. Evaporation rates for the duck creek area are shown in Figure 8-9. Figure 8-9 Duck Creek Reservoir Evaporation Rates Lower River Diversions – Non-Structural and Structural The water right application includes diversions along the lower Mokelumne River from below Camanche Reservoir to Interstate 5. Non-Structural implies the use of existing facilities with minor improvements. Under the non-structural alternative, NSJWCD existing diversion pumps and irrigation systems could be used to maximize recharge and in-lieu distribution. Additionally, the new Woodbridge Dam when completed will be able to supply the WID canal system year round, thus enabling groundwater recharge from Lodi to north Stockton. Structural alternatives consist of new diversion structures such as check dams, pump stations, and fish screens where flows would be diverted to supply direct recharge facilities or irrigation in-lieu deliveries. A diagram of the structural lower river diversion schematic can be seen in Figure 8-10. During the course of Phase I, numerous agencies from the regulatory community warned that the MRWPA would be vulnerable to legal opposition because other less environmentally damaging alternatives to reversing the historic overdraft in Eastern San Joaquin County (i.e. agricultural and urban water conservation, water recycling, tiered water rate systems, etc.). To evaluate the alternatives carried forward, the MRWPA developed the MORE Model of the Mokelumne River System based on the EBMUDSIM proprietary software package. Figure 8-11 is a schematic of the MORE Model. The MORE Model preliminary yield and cost estimates are presented in Table 8-4. 0.0 1.0 2.0 3.0 4.0 5.0 6.0 7.0 8.0 9.0 Oct Nov Dec Jan Feb Mar Apr May Jun Jul Aug SepEvaporation Rates (inches)
