It's a pipsqueak of a pond - less than an acre in size - but renovation work on it last week could bring big benefits for wildlife, including a threatened frog species.
"This benefits the Chiricahua leopard frog, ducks and other birds, deer, coyotes, bobcats, javelinas, bears and other mammals" that rely on the pond south of Sierra Vista, said Heidi Schewel, spokeswoman for the U.S. Forest Service.
The pond is part of the Brown Canyon Ranch, a site in the foothills of the Huachuca Mountains that's managed by the Forest Service.
"The work involved replacing the liner for the pond," Schewel said. "That works to keep water in the pond instead of being absorbed into the soil."
She said the work was expected to be completed by the end of last week.
Public access was limited during the weeklong project. No reopening date has been set, Schewel said.
Buildings at the historic Brown Canyon Ranch date to about a century ago and include a four-room ranch house, storeroom and corrals.
