作为正在进行的地下水管理计划的一部分，Rancho California Water District（RCWD）计划通过位于上Pauba河谷Valle de los Caballos（VDC）区域的一系列补给池，每年人工补给多达3700万立方米（30000英亩英尺）的地下水。该项目的概念是在冬季从南加州大都会水区（MWD）购买未经处理的进口水，用于人工补给，并在冬季进行后续恢复。 该系统还能够过滤维尔湖上游收集的天然径流。RCWD预计，人工补给计划将提供该地区25%的最终供水需求。设施设计包括地质水文勘探、广泛的地下水建模、HEC-2建模、泥沙输移分析、水力分析和各种土壤分析。协调地下水建模和工程，以生成最终设计。初始建模用于生成总体设计标准和基本设计，从而产生更详细的建模工作和详细设计。

As part of an ongoing groundwater management program, Rancho California Water District (RCWD) is planning to artificially recharge up to 37 million cubic meters (30,000 acre-feet) of groundwater annually through a series of recharge basins located in the Valle de los Caballos (VDC) area of the upper Pauba Valley. The program concept is to purchase untreated, imported water from the Metropolitan Water District of Southern California (MWD) during the winter months for artificial recharge and subsequent recovery during the winter months. The system will also be able to percolate natural runoff collected upstream in Vail Lake. RCWD anticipates the artificial recharge program will provide up to 25 percent of the District's ultimate water supply requirements. Design of the facilities included geohydrological explorations, extensive groundwater modeling, HEC-2 modeling, sediment transport analyses, hydraulic analyses, and various soils analyses. Groundwater modeling and engineering were coordinated to produce the final design. Initial modeling was used to generate gross design criteria and a basic design, which led to more detailed modeling efforts and a detailed design.
