Jyl Hoyt from member station KBSX in Boise, Idaho, reports on threats to the future of the Yellowstone River. Stretches of riverfront in Montana are being lined with hard walls and boulders to protect new homes from flooding. But these barriers are threatening the river's natural flow.
CURWOOD: It's Living on Earth. I'm Steve Curwood. The name Yellowstone brings to mind some of America's most wild and beautiful landscapes. And that's why so many people are moving to the area around Yellowstone National Park. New home construction in Montana's Yellowstone watershed is at an all-time high, but every new home makes the area a little less wild. And along the Yellowstone River in particular, the effects of development are starting to add up. Many new residents have reinforced parts of Yellowstone riverfront with hard walls and boulders to try to protect their homes from flooding. Now scientists say the barriers are disrupting the river's natural cycles and threatening its future as a wild river. Jyl Hoyt of member station KBSX in Boise, Idaho, has our report.
PAIGE: Okay, are we ready, you guys?
MAN: Ready to go.
PAIGE: Okay. Go.
HOYT: Outfitter Julia Paige pushes her raft into the Yellowstone River just north of Yellowstone National Park in Montana, and rows out to the icy current. Majestic purple mountains march across the horizon, throwing jagged shadows over broad green meadows. Eagles, geese, and hawks fly overhead. Great Blue Herons lift off their nest at the top of a cottonwood. Julia Paige points to something else at the top of the trees.
PAIGE: Look at how high all that driftwood and stuff is stacked in those cottonwoods. It was amazing, '96 and '97. You'd come down here and you couldn't believe how much water was coming down this river.
HOYT: In the spring of 1996, then again in 1997, record floods raged for more than a month when the river, bloated with melting snow, roared out of Yellowstone National Park. Gravel-filled waves dug entirely new river channels, swallowing houses, forest, and pastures. Montana hydrologist and environmental consultant Scott Gillilian says the floods were dramatic, but not that unusual for rivers like the Yellowstone.
GILLILIAN: Gravel bed rivers don't have predictable boundaries. They scroll across the landscape, form new channels, abandon other ones. That's the natural behavior of a river. And thereby that much more difficult to try to control and engineer.
HOYT: As we float around a bend we pass a bulldozer digging up cottonwood trees at the river's edge. The Paradise Valley, as this is called, is in the midst of a building boom. And in order to protect their investments, newcomers have been bulldozing trees and hauling in rock, trying to keep the floods away with levees, burns, and rip wrap.
GILLILIAN: There are people moving in with enough wealth that they can afford million-dollar river training projects.
LEONARD: It's not going to work in any kind of long term sense, and it does such harm to the river.
HOYT: The rip wrap is destroying important fish spawning areas, and damaging cottonwood forest that border the Yellowstone River, where song birds rest on their migration from South America. Susan Leonard, a biologist with the Montana Audubon Society, says that as the river is hemmed in from its natural floodplain, the vital cottonwood forests are disappearing.
LEONARD: Flood control structures prevent a lot of the deposition that cottonwoods need. They need to find silt soil and sand that comes downriver, and adequate moisture in order to germinate. Cottonwoods support more species of breeding birds than all other western habitats combined.
HOYT: And it's not just the environment that's suffering.

HOYT: A few miles south of Livingstone, rancher Jerry O'Hair gestures from behind the wheel of his white Dodge truck as he passes through a pasture. His family has lived along the Yellowstone for 125 years. He says he's never seen anything like what he calls the vicious floods of 1996 and '97.
O'HAIR: That rock bank that you're looking at over there is where the river cut a channel through when the river finally abated and went down along in August. The estimate was almost two thirds of the river was running down through Springvick .
HOYT: The river had jumped to a new channel, right through Jerry O'Hair's ranch. Over the next 2 years he spent nearly a million dollars in a largely losing battle to protect his pastures from the river.
O'HAIR: I hired a couple of bulldozers and put those in here, and they worked for 2 weeks 24 hours a day, and they were working in water and mud and fighting the river at that time. And that's when this road was built in here, the early part of '97.
HOYT: The road acts as a new levee and keeps the river at bay, for now. Jerry O'Hair blames the recent floods on the fires in Yellowstone National Park 11 years ago, which he says reduced the forest's ability to hold water. But many others say the major reason is all the impoundments built to protect new houses in the floodplain. In the two years between 1995 and '97, the Army Corps of Engineers issued 82 permits for riverbank barriers along the upper Yellowstone in Park County. More than twice the number approved in the previous two decades. Hydrologist Scott Gillilian says in the past few years, the river became caught up in a vicious cycle. Every flood control structure just increased the chances of flooding downstream.
GILLILIAN: You could look down on this piece of river and what you essentially had going on was dueling bulldozers. People frantically building a dike and levee on this left bank when in fact building that levee and dike put a great deal of pressure on the right bank around the corner, so those people, to defend their property, started throwing up a large levee and dike.
HOYT: So, this stretch of the Yellowstone is becoming less and less like a natural river, and more and more like a fire hose. And it's not just environmentalists that are concerned. Park County commissioners tried to pass a tough new zoning plan, and floated a flood mitigation proposal that would have strictly regulated further development on the floodplain. But both plans met strong opposition from land owners like rancher Jerry O'Hair.
O'HAIR: I can't tell my neighbor what to do or how to sell his property. It's the American way. It's the capitalistic way. When you pass rules and regulations that stop people from protecting their private property, then you're going down the other road. That's the way it is across the water in the Soviet Union.
HOYT: Ranchers are facing low commodity prices, and selling land for development sometimes is the only way to make a profit. The dilemma has left Park County Commissioner Dan Gudibeer almost despairing for a solution.
GUDIBEER: I guess you could say that the financial situation is the worst enemy, you know. People want that right to see and do what they want to do. But maybe we're destroying our history in doing so.
HOYT: The state and federal governments are worried, too. The Montana legislature and the U.S. Geological Survey have funded a study of the problem. And Montana's governor has created a task force on it. But it may be three years before the task force even issues a report. Meanwhile, houses and river barriers will continue to be built, and environmentalists like Dennis Glickman of the Greater Yellowstone Coalition are looking for ways to break the cycle.
GLICKMAN: One of the reasons that we feel like we need a time out is not just to protect the river and the riparian habitat, but basically to protect private property from the effects of what other private property owners have done. Or what the state or communities have done. Some of their bridges and some of the rip wrapping they've done have backed up water and flooded other people's property.
HOYT: Back on the Yellowstone, Dennis Glickman says it would be a tragedy if nothing were done soon to stop the piecemeal destruction of the river. Despite all the problems, he says, it's not too late.
GLICKMAN: It's really America's last best river, and I think we have a tremendous opportunity here to protect what's left and even restore a lot of what has been damaged. And I really hope that we as citizens of Montana have the guts to move forward and do that.
HOYT: For Living on Earth, I'm Jyl Hoyt on Montana's Yellowstone River.
