Biohazard Cleanup Near Downtown Ada Ada, MN

Ada is the county seat and largest city of Norman County in Minnesota's Red River Valley, at the junction of State Highways 9 and 200.

Ada was laid out in 1874 and incorporated on February 9, 1881, and a post office has been in operation there since 1876.

The city was named in honor of Ada Fisher, a daughter of William H. Fisher, the attorney and superintendent of the St. Paul and Pacific Railroad who oversaw construction of the Red River Valley rail line.

Ada had 1,740 residents at the 2020 census, living in 751 households.

Ada calls itself the 'Heart of the Valley,' and three of its buildings — the Norman County Courthouse, the Congregational Church of Ada, and Ada Village Hall — are listed on the National Register of Historic Places.

Ada survived a determined county-seat challenge from Twin Valley in the early 1900s, and when Mahnomen County was carved out in 1906, Ada became Norman County's geographic center.

Ada's students attend Ada-Borup Schools; the high school building was constructed in 1998 after the devastating 1997 Red River flood destroyed the former 1953 building.

Ada hosts the annual Norman County Fair on the last full weekend in June and the 'Fun in the Flatlands' festival each fall, featuring Pioneer Days at Prairie Village.

The Norman County Index, a weekly newspaper founded in 1883, is headquartered in Ada, and KRJB 106.5 FM broadcasts from the city.

Ada's weather station has recorded extremes of 111°F and −53°F, reflecting the Red River Valley's harsh continental climate.
