The Swan Lake Historic District in Tulsa, Oklahoma, consists of three main additions and eleven smaller additions. It was partially platted as Orcutt Addition in 1908 with the lots first offered for sale in 1910 by Samuel Augustus Orcutt. The land was part of a ranch in the late nineteenth century. The lake was a watering hole for the family’s cattle. In the early twentieth century, an amusement park was operated in the area ~ on the outskirts of town. The end of the line for the streetcar from downtown was at the west end of the lake. A dance pavilion, strung with Japanese lanterns, hosted many party-goers on summer evenings. The natatorium (swimming pool) was on the north side of the lake. The present-day house built on that site still has the curved walls in its basement from the original pool. in 1917, developer E.J. Brennan purchased the land adjacent to the south, surrounding Orcutt Lake, renamed it Swan Lake, and platted Swan Lake Addition. A niece of his lived in a house on the southside of the lake. Today, one of her granddaughtrers lives in that same house, which has been kept in the family. To the west, Park Place Addition was platted also in 1917. Other smaller additions were platted through the 1910s and 20s. Located approximately one and one-half miles southeast of the original Tulsa central business district, the Swan Lake Historic District is generally bounded on the north by East 15th Street, on the east by South Utica Avenue, on the south by East 21st Street, and on the west by South Peoria Avenue, an area of approximately 127 acres.
