Compton is connected to the broader Los Angeles basin watershed.
* **Los Angeles River:** The paved channel of the LA River forms part of Compton's eastern boundary. While heavily urbanized, the riverbanks host a popular multi-use trail. * **Compton Creek:** A major tributary of the Los Angeles River that runs directly through the city. While mostly encased in concrete for flood control, the creek features a natural earthen bottom in some lower sections, supporting local birdlife and wetlands ecology.
