Plymouth County

Plymouth County is an administrative division in northwestern Iowa spanning rolling terrain with fertile plains and extensive farmland throughout its expanse. The landscape is shaped by agricultural activities that define both the character of the region and the livelihoods of its inhabitants.

The county was established in 1851 and developed as an agricultural region. A distinctive red sandstone courthouse rose in Le Mars in 1900 and became the symbolic center of county administration.

Farmers Holiday Group formed during the Great Depression to control agricultural product prices through organized market restrictions.

The county is managed by a five-member Board of Supervisors handling public services and administrative duties. Visitors encounter a rural setting where agriculture shapes the rhythm of daily life and the landscape's character.

The territory maintains an elevation of 358 meters above sea level, featuring fertile soil conditions for extensive farming operations.
