About the City of Filer

The city of Filer was named after Walter G. Filer, who served as general manager of the Twin Falls Water and Land Company. The city was established in 1906 as the terminus of the Oregon Short Line branch of Twin Falls. Walter Filer was a mining engineer and surveyor from Sharon, Pennsylvania, who supervised the construction of the Milner diversion dam on the Snake River. Since 1916, the City of Filer has been the home of the Twin Falls County Fair and Rodeo (Magic Valley Stampede).


One of the biggest attractions every year is the Twin Falls County fair with fair grounds located in Filer. Usually starting the last day of August and into the first week of September this fair is one of the biggest and most known in the state of Idaho. From rides to concerts from some of country music's biggest names the Fair is one of the most exciting events of the year.
