DASH has two seasons: Fall/Winter and Spring/Summer.
The Fall/Winter season begins in September/October and concludes in February/March depending on swim group level. Gold, Silver and Bronze practice groups all start within the month of September and the Green I, Green II and Blue groups start in October. Competitions are short course yard meets, which are held in a 25-yard pool. The Fall/Winter season is also referred to as short course because training and competition occur in yards. The season concludes with championship meets: Iowa Swimming Regional Finals and 8 & Under Championships, Age Group (14 & Under) Championships, Short Course Championships and SPEEDO Sectionals. These meets are typically the last week of February and the first week in March.
The Spring/Summer begins in late March or early April and concludes in late July and August depending on swim group level. Gold, Silver, Bronze practice groups all start within the month of March and the Green I, Green II and Blue groups start in April. During the spring/summer season an additional group is offered for high school students called Stay Fit which starts at end of the Dubuque school year. Competitions during the spring/summer season is referred to as long course because most competitions are done in 50 meter pools. Fifty meter pools are not always available in every community so training and some competition is completed in 25 yard pools during the season. The conclusion of the spring/summer season is a series of championship meets which include the Iowa Swimming Regional Finals and 8 & Under Championships, Long Course Championships, SPEEDO Sectionals, Age Group Central Zones and national level meets for those who qualify.
