# List of Smallest Rivers in the U.S.

Many towns and coastlines hide tiny waterways that still carry history, wildlife and local pride. These short rivers can be surprising — easy to walk across yet important to their ecosystems and the communities around them.

There are **2 Smallest Rivers in the U.S.**, ranging from D River to Roe River. For each entry, data are organized with Length (m),State,Source & mouth, which you’ll find below.

## How are the lengths of the smallest rivers measured?

Lengths come from a mix of official surveys, mapping data and local records, so reported values can vary by source and season; check the Length (m) column for the figure used here and the Source & mouth column for how each measurement was determined.

## Can I visit the D River and Roe River, and what should I expect?

Yes — both are accessible to the public: the D River is near the coast (short beach access) and the Roe River flows between local springs and a larger river; expect short walks, variable flow depending on weather, and basic signage rather than developed visitor facilities.

### D River

The D River in Lincoln City, Oregon, is famously short—commonly measured around 37 m (120 ft) from Devil’s Lake to the Pacific. Tide-driven length varies, so measurements and “world’s shortest” claims depend on when and how it’s measured.
