# Mio, Michigan

Mio (/ˈmaɪoʊ/ MY-oh) is an unincorporated community and census-designated place (CDP) in Oscoda County in the U.S. state of Michigan. It is the county seat of Oscoda County. The population of the CDP was 1,690 at the 2020 census.
Mio is situated along the boundary between Mentor Township on the east, Big Creek Township on the west, and Elmer Township to the northwest. As an unincorporated community, Mio has no legal autonomy as an incorporated municipality.

## History

The community was founded in 1881 and was originally called "Mioe", in honor of Marla Deyarmond, the wife of town founder Henry Deyarmond. Other founders included Colige Comins, Reirlo Fosdick, and John Randall. A post office named Mioe opened May 3, 1882. The name changed to Mio on November 21, 1883.

### State high temperature record

Mio holds the state record for the highest recorded temperature, when it reached 112 °F (44 °C) on July 13, 1936. An identical temperature was also recorded on the same day in the village of Stanwood, in Mecosta County.

### PBB contamination event

In 1973, a polybrominated biphenyl (PBB) contamination event caused farmers in the area to destroy their herds. This event occurred when a dock worker accidentally shipped five hundred pounds of fire retardant Fire Master instead of the feed supplement Nutrimaster, leading to the contamination of various farm animals, including cows, pigs, chickens, and sheep. Shortly after, the farmers noticed deformities and sickness among their livestock and newborn calves. More than 35,000 cows were found to be contaminated and had to be destroyed. Out of these, 1,300 were dumped into a clay-lined pit in Mio. As of 2014, PBB is still detectable in the blood tests of some people in this area.

### Detroit-area hunters murdered

For nearly eighteen years, Mio was thrust into the local and national media spotlight due to a case involving two Detroit-area hunters who went missing in the fall of 1985. Progress in the investigation was stymied by area residents' refusal to help, citing fears of violent reprisal. On November 21, 1985, childhood friends David Tyll and Brian Ognjan were beaten to death with baseball bats outside of a local bar. The case was eventually cracked in 2003, when two brothers, Raymond and Donald Duvall, both from South Branch, in Iosco County, were convicted of murdering the pair near Mio. It was rumored that the murderers had disposed of the bodies by feeding them to pigs. When the two brothers were sentenced to life in prison without parole, Tyll's father said, "They took my son. It doesn't bring him back, but it's something." A true account of the crimes was detailed in Darker Than Night, a 2006 book by Tom Henderson.

### Historical markers

There are two historical markers in Mio.
* Mio Hydroelectric Plant was built in 1916 on the lower Au Sable River. William W. Tefft, a Consumers Power civil and hydraulic engineer, invented and patented the so-called "conduit spillway", which channels excessive flow through channels built into the plant. This was the first plant to use it, and it is cheaper than other forms of spillways.
* Oscoda County Courthouse was built in 1888. It was destroyed by a fire on May 5, 2016. Construction of a new building officially began on May 20, 2019, and was completed in February 2020.

## Amish community

In 1900, Mio’s first Amish settlers arrived from Geauga County, Ohio. These settlers were considered "Old Order Amish" and followed strict rules. The fairly inexpensive land prices brought in more Amish settlers, and in the first five years, the community grew rapidly. The settlers took advantage of the once wooded land by growing clover, hay, peas, corn, and potatoes, as well as other bumper crops. Eventually, the Old Order Amish began to dwindle in numbers due to a large number joining the Amish-Mennonite congregation, which held more progressive beliefs. In 1954, the Old Order Amish became extinct when the congregation's last bishop passed away. In 1970, a new group of Amish, also from Geauga County, Ohio, settled in Mio, founding the fourth oldest Amish community. The three church district community is home to around 400 individuals. Although many of the Old Order Amish transitioned to following the Mennonite congregation due to their more progressive beliefs, the Amish that are settled in Mio today still follow a strict set of commands. However, Amish commands do vary from community to community.

## Education

The area school district is Mio-AuSable Schools, which includes all of the CDP.
Mio-AuSable Schools is a Kindergarten through 12th grade school, with all grades contained in one building. Middle school and high school students are enrolled in seven classes each day, and the year routine follows a semester schedule. Mio-AuSable currently offers two Advanced Placement (AP) courses, AP Biology and AP Calculus AB. The school does not offer any Honors courses, but to make up for the lack of advanced classes, students are encouraged to dual-enroll through Kirtland Community College. Sophomores, juniors and seniors can choose to take online classes through the nearby community college, and if the students receive at least a C in a course, they will be granted college credit in that course which may transfer into the university of their choice after high school.
The high school has about approximately 170 students and 17 teachers, some of which double as middle school teachers.
