In 1953, Morgan Sweitzer of Delta approached what is now Colorado Parks and Wildlife, offering some of his land for a dam to be built. His wish was to create a lake so people could boat, swim, fish and picnic. The land was an alkali draw, so it was too steep and too salty to farm. The state of Colorado accepted the property and constructed the dam. The dam was filled using 19 shares of irrigation water from the Uncompahgre Water Users Canal.
During the 1950s, a boat ramp, swim beach and small campground were built, though overnight camping would be discontinued in 1981. The number of visitors in these early days was quite high (some say as high as 80,000 to 90,000 annually) because this was the only recreational lake on Colorado’s West Slope from Douglas Pass north of Grand Junction south to Red Mountain Pass, and from the Utah line east to McClure Pass.
In August 1960, the newly appointed Parks Board received the transfer of Sweitzer Lake from the Game and Fish Department to the newly formed Colorado State Parks and Recreation.
Since 1972, the area, with its 137-surface-acre lake and 211 land acres, has been managed by Colorado Parks and Wildlife.
