California is home to a diverse network of waterways, including rivers, lakes, and coastal areas. Major rivers like the Sacramento River and San Joaquin River play crucial roles in the state's water supply and ecosystem. The Colorado River also provides water to Southern California, while numerous lakes, such as Lake Tahoe and Mono Lake, offer recreational opportunities and support local wildlife. The state's coastline stretches over 800 miles along the Pacific Ocean, featuring estuaries and wetlands that are vital for marine life. These waterways are essential for agriculture, drinking water, and recreation, making them a key part of California's environment and economy.
