Rio Dell is a city in Humboldt County, California, United States. Its name comes from two words: Río (Spanish for "river") and Dell (English for "small valley in a woodland"). The city is located on the west side of the Eel River. It is about 1 mile (1.6 km) north of Scotia. The city sits at an elevation of 161 feet (49 m) above sea level. In 2020, about 3,379 people lived in Rio Dell.

History of Rio Dell

How Rio Dell Got Its Name

The name Rio Dell comes from the old Rio Dell Hotel. The hotel owner, Lorenzo Painter, combined the Spanish word río (river) with the English word dell (a small wooded valley). This name describes the area well, with its river and green surroundings.

Early Days and Native Peoples

Before it was called Rio Dell, the area was home to several Native American tribes. These included the Wiyot, Nongatl, and Mattole tribes. They reportedly called the area "Tokemuk." After a difficult period for the native people, the area became known as Eagle Prairie. Eventually, it was renamed Rio Dell.

Connecting Communities

The first post office in Rio Dell opened in 1876. For a long time, a ferry connected Rio Dell to Scotia, helping lumber mill workers travel. After a flood destroyed the first bridge in 1905, ferries continued to operate. A new suspension bridge to Scotia was finally built in 1914.

Wildwood and the Lumber Industry

Many Italian immigrants settled in an area south of Rio Dell. This part of town was known as Wildwood, and sometimes as Little Italy. It became a popular place for mill workers. Rio Dell's main street is still called Wildwood Avenue today. In 1928, a big fire destroyed many buildings on this street.

Rio Dell became an important home for workers of the Pacific Lumber Company. This was one of the largest lumber mills in the world. Many immigrants, especially from Italy and Portugal, first settled here.

Becoming an Official City

Rio Dell officially became a city in 1965. This happened because the community was growing after World War II. Also, the local Sheriff's office found it hard to provide enough police services to the area. Becoming a city allowed Rio Dell to create its own police department. This gave the community more local control over safety.

However, over the next 20 years, the city faced some challenges. A new freeway bypass changed traffic patterns. Also, the Pacific Lumber Company eventually became a smaller employer. These changes affected the city's economy.

Recent Events

Rio Dell was affected by an earthquake in 2022. This event caused shaking and some damage in the area.
