Our History




The old building that still stands on the corner of Main and Tecumseh dates back to 1881. It was first called the "Excelsior Mill". At some point in the late 1880's, the mill was converted from the stoneground process to a roller mill. Sometime before 1918, the old mill was called Ottawa Milling Company and was controlled by a flour mill in Kansas City.

In September 1919, the old mill was purchased by members of the Ross family. The mill in Ottawa was then called the Ross Milling Company. Production of flour was raised to 1200 one hundred pound sacks per day and shortly thereafter a new 120,000 bushel concrete grain elevator was built. The Ross Milling Company was operated for thirty-one years, but after several floods in the 1940's it was dismantled and sold in 1950 to the Ottawa Cooperative Association.

In 2001 the Ottawa Cooperative Association purchased several locations from the Farmers Cooperative Association formerly located in Lawrence, KS. This expansion tripled the capacity of the Ottawa Cooperative Association, yielding a total of 14 locations.

From the spring of 2006 to August 2007 the Ottawa Coop added over 800,000 bushels of additional grain storage. The addition was spread across 4 locations - Burlington, Waverly, Ottawa and Scranton. This addition brought Ottawa Coop's capacity to 8,044,000 bushels as of August 31, 2007.

Prior to the 2008 Harvest the Ottawa Coop added a high speed leg and dump to the Elevator "D" Complex in Ottawa, KS and then added a second bin prior to the 2009 harvest. The Midland facility north of Lawrence was also renovated to replace a couple bins which had sustained damage in previous years. This brought the Ottawa Coop to a current storage capacity of 8,386,000 bushels for the 2009 harvest.
