## Geography

Rio is situated in the northwest corner of Knox County, 13 miles (21 km) north of Galesburg, the county seat. Like other rural neighbors, the village has rich soil ideal for farming corn and soybeans. A few small, unnamed creeks run through its outskirts, and a few small hills that coast under the streets of the village. A few sizable dropoffs throughout the land almost look like shallow or gradual cliffs as some local agricultural fields are rolling and steep. The land drains to North Henderson Creek, a west-flowing stream leading to Henderson Creek to the Mississippi River near Oquawka.
According to the 2010 census, Rio covers a total area of 0.27 square miles (0.70 km$^2$), all of which is land.

## Education

ROWVA School District #208 comprises five major towns: Rio, Oneida, Wataga, Victoria, and Altona. Pre-K to 2nd grade students attend ROWVA Central in Oneida, 3rd and 4th graders attend ROWVA West in Wataga, and 5th and 6th graders go to ROWVA East in Altona. The junior high, which encompasses 7th and 8th grades, is in Oneida, as is the high school for grades 9th-12th. ROWVA Central, ROWVA Jr. High, and ROWVA High School are all part of one basic building, separated into different sections. ROWVA's school colors are black, gold, and white, with their mascot being a tiger. The school is ending a five-year-long football co-op with AlWood at the end of the 2009 football season, in which they are the A&R Bulldogs (black, silver, and white.) Starting in the 2009 fall season, ROWVA is also part of a sports co-op with Galva where they are the Mid-County Cougars (black, blue, and white.) ROWVA is a part of the Mid-County co-op for golf, cross country, junior high football, and will be adding high school football starting in the 2010 football season.
Previously, Rio had its elementary school, which stands in the town center near the corner of Grande Avenue and North Main Street. It was opened in 1922, the school was closed permanently in 2004 due to high energy costs, a lack of efficient output of students (36 students at date of closing for grades 1–6), and other reasons. After its closure, the building was purchased by Mike Gillette, who agreed to let local children utilize the modest and rusty playground equipment (which has since been removed) as a makeshift park. It has not been transformed into any business, and virtually no architectural or exterior changes have been made.
The village of Rio owns a baseball diamond and the land plot to its west and has turned it into a park with a public pavilion and concession stand for ballgames as well as a large playground structure that was paid for by the village and constructed during a community build day in July 2012.
