1950 Map of Bottomless Lakes

About this map

Bottomless Lakes State Park follows a dramatic line of sinkholes and deep water bodies along the eastern edge of the Pecos River valley. This 1950 survey highlights the unique hydrology of the Pecos Valley, where several distinct lakes—including Mirror Lake, Inkwell Lake, Figure Eight Lake, and Lea Lake—formed within the escarpment. To the west, the river creates a wide, braided floodplain, while the Hagerman Canal and various Ditch systems indicate the intensive irrigation efforts of the mid-century era. Land use in the surrounding Chaves County desert is defined by a mix of ranching and early petroleum development, evidenced by the Ervin Ranch and Atkinson Ranch alongside numerous abandoned oil wells and scattered oil tanks. The Fin and Feather Club near Dimmitt Lake suggests the area's established role as a recreational destination for local residents during this period.
