U.S. Geography: Water & Climate

The North American Continental Divide is an imaginary line that runs through the Rocky Mountains and separates the way water flows across the continent. On one side of the divide, rivers and streams flow toward the Pacific Ocean, while on the other side, they flow toward the Atlantic Ocean or the Gulf of Mexico. It is like a giant rooftop, where rainwater falling on one side goes one way, and water on the other side goes a different way. The Continental Divide is important because it helps shape rivers, lakes, and ecosystems across North America!

Contiental Divide

A watershed is an area of land where all the water—whether from rain, snow, or streams—flows into the same larger body of water, like a river, lake, or ocean. Watersheds are important because they provide drinking water, support wildlife, and help prevent flooding by directing water naturally through the land. In Indiana, most of the state is part of the Mississippi River Basin, which drains into the Gulf of Mexico. In Southern Indiana, water flows into the Ohio River Watershed, which collects water from smaller rivers and streams like the White River and Blue River before emptying into the Ohio River. The Ohio River then carries this water into the Mississippi River, showing how smaller watersheds connect to larger ones. Understanding watersheds helps us protect water quality and manage resources wisely.
