RICH LAKE. Rich Lake, also known as Laguna Rica, is eight miles northeast of Brownfield in northeast Terry County (at 33°17' N, 102°11' W). The moderately saline Rich Springs feeds the lake. Potsherds and flint points have been found around the lake. Legend is that the lake and springs were so named by Spaniards because of the rich deposits of salt at the site; the salt was later used by buffalo hunters in curing meat. Anther story is that Spaniards about to be attacked by Indians buried a treasure there.
