History of Underwood, Iowa

Underwood is part of Norwalk Township. The early history of this area helps us understand how the town grew.

Early Settlers and Mills

The first people to settle in this area arrived between 1845 and 1850. In 1847, two important mills were built on Mosquito Creek. There was a flour mill to grind grain and a saw mill to cut wood.

However, in 1850, a big flood destroyed the flour mill. Even so, more homes were built near the saw mill and the first school, which opened in 1863. This small settlement became known as Downsville. It even had its own post office.

How Underwood Got Its Name

The town of Underwood began in 1869 when the Chicago, Rock Island and Pacific Railroad came through. It was built about three miles northeast of Downsville. Eventually, Downsville was left behind and disappeared, though its cemetery remains.

In 1882, another railroad, the Chicago, Milwaukee and St. Paul line, built a station here. They also added a water tank and a switch for trains. These new railroad features were built on land owned by two local farmers.

The town was named Underwood after the first engineer who drove a train on the Milwaukee tracks. Two farmers helped by clearing a path through their cornfields for the depot. This path later became the town's "Main Street."

Growing as a Town

Underwood officially became a town in 1902. The town council appointed a marshal to keep order and built a jail. They also started building sidewalks.

In 1903, the town grew with its first new addition of land. The old school building was moved and became the town hall. By 1905, the town bought five street lamps and extended its sidewalks and streets.

Between 1907 and 1910, modern services arrived. The telephone came to town, a water system was installed, and more cement sidewalks were built. A fire department was organized in 1917 to protect the community.

In 1926, a new, larger school was built for about $75,000. It had 62 high school students and 116 younger students, taught by seven teachers.

Recent Developments

In 1965, sewer pipes were installed in the town. A new Western Electric plant was completed in 1974, which helped update the town's sewer system.

More recently, in 2012, Jack Link's opened a distribution center in Underwood. They also gave a $15,000 donation to the community.

Geography and Location

Underwood, Iowa, covers about 0.46 square miles (1.2 square kilometers) of land. It is located in a special area called the Loess Hills. These hills are a unique prairie formed by windblown soil that was deposited after the last Ice Age.
