… The Tehama-Colusa Canal, which runs north to south along the western edge of the Sacramento Valley, will function as the primary outlet for Sites Reservoir, a long-planned water storage project. Its construction has been approved to begin later this year. The largest California reservoir project in decades, the reservoir will collect and store water in wet years and release it to customers during dry ones. When it does, it will start in the Tehama-Colusa Canal, which dead-ends just south of Dunnigan. To continue, the water needs to cross miles of farmland, roads and Interstate 5 to reach stakeholders in Southern California and elsewhere that have invested in the project. Engineers from the Sites Project Authority, which is in charge of building the reservoir, designed a solution in the form of the pipeline, which would run underground and dump into the Colusa Basin Drain.
