The Hardy River (Spanish: Río Hardy) is a 26-kilometer (16 mi)-long Mexican river formed by residual agricultural waters from the Mexicali Valley, and running into the Colorado River. The river is believed to have been an ancient channel of the Colorado, as well as the primary outflow for the prehistoric Lake Cahuilla.
