South Texas officials intend to raise $2.5 million by selling 600 acres of a dry salt lake that borders the Lower Rio Grande Valley National Wildlife Refuge.
The La Sal Vieja lake in Willacy County has been a valuable resource for people dating to the ancient Aztecs.
The Delta Lake Irrigation District wants to raise money to repair canals and other infrastructure.
General Manager Troy Allen tells the Valley Morning Star that the district has set a July 16 deadline for bids on the acreage.
The federal government was interested in purchasing the land to expand the size of the refuge, but its funding ran dry.
La Sal Vieja is about six miles from a larger salt lake, La Sal del Rey, that sits atop a massive salt dome.
