These efforts transform the landscape, initially focusing on flood control and, subsequently, irrigation. Early irrigation was dominated by small-scale initiatives and groundwater usage, but by the 1970s, irrigation districts became the primary water suppliers.

There are eleven provinces, including the Great Valley, Modoc Plateau, Klamath Mountains, Sierra Nevada, Transverse Ranges, Cascade Range, Coast Ranges, Peninsular Ranges, Basin & Range, Mojave Desert, and Colorado Desert. These provinces offer diverse landscapes.

The valley formed through the subduction of the Farallon Plate, leading to sediment accumulation. Over time, it evolved into a fertile landscape rich in natural resources, including oil and gas, but it is also prone to natural hazards like earthquakes and floods.
