In the 1920s, what was purportedly the largest outdoor swimming tank in the state stood in Bend on the banks of the Deschutes River just downstream from Pioneer Park. The 50 x 150 foot steel tank held 330,000 gallons of water. Its water came directly from the Deschutes River, was heated by a burner using sawdust from Bend sawmills, and then returned to the river. The swimming tank was part of the Bend Auto Court complex built in 1927 by the three Kirtsis brothers, immigrants from Greece who had earlier homesteaded east of Bend. The tank was open to the public as well as Auto Court guests, and the daily entrance fee was 10 cents.
