O'Brien County Conservation Board now own the park!
On March 12, 1935, bonds were offered for sale by the First National Bank of Paullina. The $20,000 raised was used to purchase land for the park and to initiate park improvements. The park was transferred to the ownership of the State Conservation Commission on October 25, 1935. Seventy six years hae passed and the O'Brien County Conservation Board has now received ownership of Mill Creek State Park.
Due to vision and diligence of community members, the park project began. Through the years, many citizens, the City of Paullina, and the O'Brien County supervisors have continued to make improvements
