When was Moon Lake by Eudora Welty written?

Eudora Welty was born on  April 13, 1909 in Jackson, Mississippi. Her mother was a schoolteacher who instilled in Welty a love of reading. Welty's father was an insurance executive. The Welty family thus belonged to the upper middle classes. After finishing high school in 1925, Welty attended  Mississippi State College for Women, then graduated with a degree in English from the University of Wisconsin. She spent most of her adult life in her home town of Jackson and her writing is mainly set in the Mississippi Delta and based on her own experiences and observations of that region, albeit with an admixture of mythology. She began publishing short stories in literary magazines and commercial magazines such as the New Yorker that catered to educated audiences. 
Her short story "Moon Lake" was initially published in the Summer 1949 issue of the distinguished souther literary magazine The Sewanee Review (Volume 57, No. 3, pages 464-508). It also appeared in Welty's 1949 short story collection The Golden Apples, a collection consisting of seven stories set in Morgana, Mississippi. The story was probably written in 1947 or 1948.
