本文描述了连接加利福尼亚州散装水输送系统的系统，该系统是世界上最大的。该系统拥有700多英里的运河和管道、23个抽水计划、130个水力发电机组和90多个流量控制结构。控制系统的主要组成部分包括:运行中心、开发和决策支持系统、灾难性备份、位于渡槽沿线的4个区域控制中心；8个主要电厂控制系统、10个次要电厂控制系统、流量控制结构和其他点的129个RTU，以及两个系统通信枢纽。本文介绍了设计原则、测试、使用网桥而非路由器的原因的一些讨论、所选网桥的特点以及警报。

This paper describes the system that ties together the State of California's bulk water conveyance system, which is the largest in the world. The system features more than 700 miles of canals and pipe, 23 pumping plans, 130 hydroelectric units, and more than 90 flow control structures. The primary components of the control system include: the operations center, development and decision support system, catastrophic backup, 4 area control centers located along the aqueduct; 8 major plant control systems, 10 minor plant control systems, 129 RTUs at flow control structures and other points, and two system communications hubs. The paper describes design principles, testing, some discussion of the reasons to use bridges rather than routers, the features of the bridges chosen, and alarms.
