“The river is dry because everybody’s taking water out”, says Austin. “We’re putting water in.”
Austin’s Rancho El Coronado, not far from famed 19th Century Indian leader Cochise’s mountain stronghold, and Rancho San Bernardino, spanning the international border near Douglas, Arizona, and Piedras Negras, Sonora, are Cuenca Los Ojos’ project sites for reviving the Rio Yaqui.
They were once
ciénagas, or swamps, as indicated by the telltale dark silty talcum powder like soil. They are part of a once-vast wetland, now reduced to a fraction of its former self by poor land use practices, such as lumbering in the mountains and cattle ranching in the valleys.
“We’re trying to raise the level of stream beds so water will overflow again, spread out, and plants associated with the
ciénaga will start coming back,” says Austin.
“It was dry where we are, and now there are three miles of water running through Rancho Coronado. There is water year round in the river. The land holds it like a sponge. The sponge becomes more and more beneficial for the whole Rio Yaqui system. You want to get the whole river to do that.
A century after Geronimo, CLO sent out teams to construct loose rock structures up hillsides and to shovel up earth berms with heavy machinery in order to plug erosion and capture water. This serve the purpose of slowing down the runoff from monsoon rains and catching sediment that would otherwise wash away.
They built larger dam-like structures called gabions by filling wire baskets with rocks. Eventually the gabions became buried and the riverbed was raised. Now each year the gabions are being built higher. The sediment is expected to collect enough for water to spill over the surface of the terrain, re-forming the wetlands.
Austin’s concerns are for the long term and the big picture.
