Lesson 4: Transforming the Land

Key Idea

As people settled and worked in California's different regions, they began to change the environment to meet their needs. They saw the land and its features as natural resources that could be used for farming, mining, and building communities.

To make farming possible in dry areas, settlers developed systems of irrigation, building canals and dams to move water from rivers to their fields. In the mountains, miners rerouted streams to search for gold, and forests were cleared to make way for growing cities and towns. These actions reshaped California's landscape, allowing the state's economy and population to grow.

Key Idea

In areas with little rainfall, farmers needed a way to bring water to their crops to ensure a successful harvest. This was a major challenge for growing food and supporting a settlement.

To solve this problem, people built irrigation systems. They dug canals and ditches to channel water from rivers and lakes directly to their fields.
