Once a shimmering lake 70 km southwest of Santiago, Laguna Aculeo was full of life, fed by the Andes and visited for swimming and sailing. In just a decade, drought, population growth, and water-intensive farming dried it out completely. Where boats once floated, cattle now walk across cracked earth. Still, some hold on to hope — whispering that all it needs is rain, and the lake will return to life once more.
