From mavensnotebook – California.com – Nestled in the heart of California’s vast Central Valley lies a shimmering oasis, a testament to human ingenuity and the ongoing quest for water management: the San Luis Reservoir. This magnificent reservoir, holding both natural beauty and immense significance for the Golden State’s water system, is much more than just a large lake. Here’s everything you need to know about this impressive structure. Water is pumped into the reservoir primarily from the Sacramento-San Joaquin Delta during periods when water is abundant. The reservoir then releases the stored water during dry periods, ensuring a consistent water supply for agricultural, municipal, and industrial users downstream. The water stored in San Luis Reservoir not only quenches the thirst of urban areas such as Los Angeles, San Jose, and San Francisco, but also irrigates the fertile farmlands of the Central Valley, which contribute significantly to California’s economy. The reservoir acts as a buffer, ensuring that water is available throughout the year, especially during California’s frequent and sometimes prolonged droughts. (more)
