Rivers & Water

The Brazos River Borders Johnson County to the Southwest

Johnson County has two main waterways — the Brazos River on its southwestern edge and the Nolan River running through the middle of the county.

Johnson County The Great Outdoors

The Brazos River forms the county's southwestern boundary. It is one of Texas's major rivers and can flood after heavy rains. The Nolan River flows north-south through the county and was dammed to create Lake Pat Cleburne in 1961.

If you own land near either river, check FEMA flood maps at msc.fema.gov before buying or building. Low-water crossings on rural roads can become impassable quickly after storms. The TSHA Handbook has more on the county's geography and waterways.
