Missouri has been traditionally blessed with abundant and diverse water resources like few other states in the nation. The quality of life for each Missourian can be closely tied to the health of our state’s natural resources. Ensuring we are able to enjoy our Missouri waters today as well as ensure the same for future generations is the essence of the Missouri Department of Natural Resources’ mission.

A watershed is an area of land that drains water into a particular lake, river or wetland. A group of watersheds that drain into a major water body is often referred to as a basin. For instance, all of the land that drains water into the Missouri River from Three Forks, Montana, to St. Louis, Missouri, is referred to as the Missouri River Basin. Watersheds can be divided into smaller watersheds such as an area surrounding a specific small creek or stream. Learn about the benefits of a healthy watershed, why your watershed is important and how you can help protect our watersheds.
