History
El Dorado Springs was founded in 1881, near a natural spring by brothers Nathaniel and Waldo Cruce who attempted to capitalize on the namesake's spring water. A post office has been in operation at El Dorado Springs since 1881.
An annual tradition is the Founder's Day Picnic which began early in the town's existence as an annual gathering for residents. It is a three-night event which has grown to be the largest attraction of the year and brings thousands of visitors to town. In recent years a carnival has provided rides and the City Council hires performers to give free concerts in the City Park. This upcoming picnic will be the city's 135th. El Dorado Springs boasts Missouri's oldest municipal band performing in the United States at the longest continually used bandstand.
