Out West, a lot of cities figure many more people will be moving in over the next few
decades. Water engineers wish those people would bring along all the water they’ll
need, but of course they won’t. Shawn Allee reports these cities want to pipe more
water from far away, and some people think that’s a bad idea:

The air in Colorado Springs is usually so dry it quickly chaps your lips.

What gives? Colorado Springs sounds wet enough.

“There’re really no springs in Colorado Springs, so when you start talking
about water, it’s a divergence between our name and reality. Sounds like we
had a lot, and in reality we didn’t.”

This is Matt Mayberry, Colorado Spring’s historian.

I’ve heard about this massive water pipeline project the town’s cooking up, and I was
curious just how long the city’s worked to quench its thirst.

Mayberry’s got an exhaustive book on that with an exhaustive title.

“Blah, blah, blah … the emergence and appropriation of rights in Colorado
Springs.”

The crib notes version?

Early on, buffalo manure poisoned Colorado Spring’s creek, so people dug wells.

Then, the wells got infested with grasshoppers.

And the town grew, and grew, and grew again.

“Very soon you had to bring water from further away, and ultimately to the
Western Slope which is a couple hours drive of here.”

Today, Colorado Springs pipes water through the Rocky Mountain range.

Doing the extraordinary for water is kinda ordinary for Colorado Springs.

Its latest pipeline project is called the Southern Delivery System, and it’ll pump nearly
80 million gallons into town each year – and it’ll pump that water forty five miles –
completely uphill.

Impressive, but some people are asking tough questions about it.

“Our concern with this project is the greenhouse gas emissions that it would
contribute to.”

Stacy Tellinghuisen is with Western Resource Advocates, a Colorado environmental
group.

She says there’s a connection between pumping water uphill and a large carbon
footprint.

“Water is heavy. Pumping it over a great distance takes a lot of energy, and
in the process it would require something along the lines of 60 MW of power,
which is about a tenth of a power plant.”

And, for the most part, the utility burns natural gas and coal to generate power. Both
emit carbon dioxide, a greenhouse gas.

Tellinghuisen says Western cities are considering at least five other water pipeline
projects, some with even larger carbon footprints.

She wants Colorado Springs to set an example by using dedicated low-carbon sources
like wind power for its water pumps.

I ask the Colorado Springs Utilities about that.

Keith Riley helped plan the Southern Delivery System.

“We think there are some ways we can minimize the carbon footprint by
looking at some new technologies.”

Riley says there were lots of environmental regulations to wade through before the
Southern Delivery System got approved.

But a large carbon footprint doesn’t disqualify utility projects.

Riley says, even if carbon were considered, the project might have gone forward
anyway because the city’s expected to grow over the next few decades.

“Water is the essential element for all of us, so when it comes to that level of
sustaining our own lives, then you get to some trade-offs on what we’re
willing to do to keep ourselves alive where we we live, where our cities are.
No matter what happens, we’ve got to move water to Colorado Springs, and
we’re uphill from the river, so we’ve got to get the water uphill one way or
another.”

Riley says Colorado Springs Utilities is considering low-carbon renewable power for its
new pipeline.

But it’ll be expensive, and no one’s stepped forward with all the money.

Other Western cities are engineering clever ways of moving loads of water around,
too. And it’ll be a political and financial challenge for them to pay for the carbon
footprint.

Tiny Pest Threatens the Las Vegas Lights

Hoover Dam generates some of the power that lights Las Vegas all night long. But there’s something

Transcript

Hoover Dam generates some of the power that lights Las Vegas all night long. But there’s something
that’s making that job a bit more difficult. Shawn Allee found out, it’s a tiny aquatic pest:

The usual tour of Hoover Dam starts at the visitor’s center – way at the top.

Robert Walsh works with the federal agency that runs Hoover.

He says, go ahead – look over the edge.

Allee: “OK. That’s creepy. Seriously, that’s creepy.”

Walsh: “It’s spooky. Are you afraid of heights?”

Allee: “No, they don’t bother me at all.”

The dam stretches down 700 feet, and it holds an enormous reservoir – Lake Mead.

This tour is awesome, but Walsh says there’s another tour, too.

It’s, um, NOT so awesome.

It’s all about the trouble the tiny quagga mussel is causing Hoover and other nearby dams.

To get that tour, Walsh takes me to Leonard Willet.

Allee: “Where are we right now?”

Willet: “It’s kind of a work station where all the quagga mussel control activities take place
for Hoover Dam.”

Allee: “It’s quagga mussel central for this area?”

Willet: “Exactly.”

Willet first heard quagga mussels were growing in the nearby Lake Mead reservoir in 2007.

He called an expert for advice.

“First thing out of her mouth was, ‘I’m sorry to hear that.’ I knew it was a lot more serious.
And I asked her what we’re in for.”

Willet learned quickly enough – quagga mussels attach to nearly anything underwater.

He shows me a sandal that was in water – and is smothered in them.

They’re like clams the size of your pinky fingernail.

“We went from zero to THAT in seven months.”

And that’s the problem.

Hoover Dam uses water from Lake Mead to spin generators.

The water moves around in pipes – and quagga mussels can attach to them – just like on that sandal.

Allee: “What does that mean in a real practical sense?”

Willet: “Our intake towers would close off. Once you start closing off, you can’t spin the
generators. That’s just kind of the big view of it.”

Zero power generation.

That’s the worst-case scenario. It hasn’t happened – but it’s a fight to prevent it.

“Now, we’re going to go down to the third floor, which is the generator floor.”

The generators are inside broad metal cylinders.

Big water pipes turn the generators. Smaller ones cool them off.

“Well, we circulate cold water from those pipes. If those start to plug up with mussels, then
you can’t keep a generator cool, if those … it shuts down due to overheating.”

Right now, it takes a lot of scraping to keep everything clear.

All this effort’s adding up – Willet says he’ll spend 2 million dollars soon on new equipment.

Even with that, Willet is still a bit jittery about some pipes outside, at the very bottom of the dam.

“The one that’s probably the scariest of all is, we have a fireline that runs around here.
Mussels love it. Then, your firelines, when they’re needed, are plugged with mussels. So
that’s another area you have to really be careful of, safety-wise.”

This didn’t have to happen.

Quagga mussels invaded eastern rivers and the Great Lakes first.

Experts figure the mussels hitched a ride West on someone’s fishing boat.

Apparently – someone didn’t clean their boat properly – and mussels dropped into Lake Mead.

Allee: “When they built this amazing structure during the Depression, do you think they had
any idea that something like this could ever happen?”

Willet: “I think there was a lot of disagreement among professionals that a little mussel the
size of your finger nail could impact a large hydro facility, but we’re quickly learning a bunch
of them can impact water and power delivery.”

Willet says if boaters aren’t careful – they’ll spread quagga mussels to the Pacific Northwest, where
there’re lots of dams and hydro power plants.

After all, if it can happen at mighty Hoover Dam – it could happen anywhere.

Learning to Live With Less Water

Droughts are nothing new for the Western US.
But lately, even some parts of the country
surrounded by water have gotten a taste of
droughts. Rebecca Williams reports as our
population grows, some experts say we’re going
to have to learn to live with less water:

(sound of birds)

Even in swampy, muggy Florida, people have been running out of water.

“This is the first time the well has ever gone dry.”

Ellen Peterson remembers water gushing out of her artesian well when she’d hook up the hose. These days she’s stuck with rusty water from her shallow well.

(sound of faucet turning on)

“Now if I let that sit it would settle out orange.”

We visited Peterson at the tail end of this year’s dry season. In the weeks since then, Florida’s been pummeled by major thunderstorms. But Florida water managers say it’s too early to know how much the rain will help.

This was the driest dry season Florida’s felt in more than 75 years. And it’s the third year in a row of serious drought. That’s meant some changes for people who live here.

Many cities put rules in place that limit watering lawns to one or two days a week. One woman actually ended up with a warrant out for her arrest after she watered her lawn on the wrong day and didn’t pay the fine.

Some cities in Florida are talking about adding a drought surcharge to bills for people using the most water.

Ellen Peterson says local water managers have even been capping wells in her area. Peterson may be 85 years old, but that didn’t stop her from telling her local official to back off.

“They told me they were going to cap my well and I threatened the guy with his life if he ever came back. (laughs) It hasn’t happened yet.”

So it’s not such an easy sell to get people to cut back on water.

(sound at a lake)

But that’s Gary Ritter’s job. He’s a water manager in the Lake Okeechobee area. It’s a giant lake – 35 miles wide – and it’s nicknamed the liquid heart of the Everglades. The lake level is 2.5 feet below average.

“For water to get to the Everglades it has to come from Lake Okeechobee. Now we have a juggling act as to how we manage this water in the system you know for multiple users for the water supply and for the ecosystem.”

The lake’s the center of a huge tug of war. Farmers and cities need the water, and the lake’s also a big tourist draw. And the Everglades are in major trouble – mostly because the water flow to this fragile area has been cut off by people.

Some experts say these kinds of conflicts are just going to get worse.

Peter Gleick is president of the Pacific Institute. It’s a nonpartisan group that studies water issues.

“Places we didn’t think were vulnerable to water shortages in the past are now increasingly vulnerable. As our population continues to grow and our water supply doesn’t. As more and more people try to share that fixed resource there’s going to be growing competition for water and more natural and manmade drought.”

And he says we just don’t know what’s in store for us as the climate changes because of global warming. We could get a one-two punch.

First, from weird new weather patterns. And second, from more and more people moving into dry areas.

People have expected these kinds of problems for cities in the desert Southwest. But nobody really saw this coming in the Southeast.

Peter Gleick says even if you live in a place surrounded by water now, you shouldn’t expect to always have plenty of it.

Rare Right Whale Recorded

Scientist think they’ve found
a rare whale in a place where
they thought they were wiped
out. Sadie Babits reports,
they haven’t seen the whale
but they’ve heard it:

Scientists thought the North Atlantic Right Whale
was gone. Only two of them have been spotted in
the last 50 years off the southern tip of Greenland.

But some underwater microphones picked up right
whale calls.

“They sound like mmmmmmick… kind of like that.”

That’s David Mellinger. He teaches at Oregon State
University.

He says they recorded more than two
thousand right whale calls in a year. That doesn’t
mean there are a lot of the whales, but Mellinger
says hearing any in the North Atlantic is significant.

“Because the population is so endangered. There
are only 300-350 maybe right whales in the world.
So finding any new whales is important.”

But there is a concern. As the Arctic Ice Cap
melts because of global warming, more ships are
expected to pass through the area. That could
mean ships could strike and kill the few right
whales that are left.

Saving Salmon From Sea Lions

The Columbia River in the Pacific Northwest historically has been a super highway for salmon. But dams, development, and pollution have taken their toll on salmon.

The Columbia River in the Pacific Northwest historically has been a super highway for salmon. But dams, development, and pollution have taken their toll on salmon. The fish have declined to the point that several species are endangered. Now the salmon face another threat, sea lions. As Sadie Babits reports wildlife managers are trying to get rid of the sea lions to protect the salmon:

Bobby Begay steers his small boat up the Columbia River. He knows this river, and he
knows the salmon. His ties to the salmon go back generations.

As a member of the Yakima Tribe, he comes out here to tribal fishing sites to catch
salmon. It’s something Indians along the Columbia River have been doing for thousands
of years. He says the salmon are considered sacred food.

“It’s part of our livelihood. It’s part of our health and well being.”

They use the salmon to feed everyone from the tribal elders to the children. Tribal
fishermen tell stories of seeing so many salmon in the Columbia River that you could
walk across their backs. Those days are gone.

A series of dams on the river make it hard for fish to get from the Pacific Ocean to fresh
water and back again. The salmon have fallen victim to over-fishing, agricultural
pollution, and habitat destruction. Pacific salmon are now listed as endangered. And they
face yet another threat on the Columbia River – sea lions.

“Sea lions have probably always been in the Columbia but not to this extent and have
done damage to salmon populations like it has and all of it is due because of a man-made
structure, which is Bonneville Dam.”

Sea lion numbers have exploded along the Pacific Coast. And more than a thousand of
them travel up the Columbia River looking for food. Some of them have figured out that
if they gather at the base of Bonneville Dam, they can easily catch salmon that are trying
to pass by.

Biologists estimate that every year sea lions eat some 13,000 salmon. This year, the
federal government gave state wildlife agencies in Oregon, Washington and Idaho, the go
ahead to kill up to 85 sea lions.

Begay won’t really talk about whether he thinks this is right. He’s torn.

“Well, ah, sea lion is a spiritual animal not only to us but to coastal tribes and we respect
the animal as it is, but also the salmon is a scared food to us as Columbia River Indians.”

So Begay works to protect the salmon without killing the sea lions. He works for the
Columbia River Inter-Tribal Fish Commission.

That’s why he’s out here in this boat. He patrols the river most days using fireworks to
scare sea lions away from the salmon.

Crew: “There he is 1 o’clock, 50 yards.”

(sound of gun shots and boat)

Begay’s crew shoots firecrackers over the sea lion.

“And hopefully we’ll get them into the main stem of the river and start hazing them down
stream.”

“The hazing really is not highly effective. The animals are really quick to learn.”

Robin Brown is a marine mammal researcher for the Oregon Department of Fish and
Wildlife.

Brown says they’ve euthanized seven sea lions this year. He says the decision to kill a sea
lion is made after everything else has failed.

“We have to have observed them killing salmon and steelhead, and they have to have
been exposed to all the non-lethal methods of harassment that you’ve observed here
today and shown that that isn’t detouring them from being here and feeding.”

The Humane Society opposes killing the sea lions. It’s asked the courts to put a stop to it.
While this legal battle plays out, Bobby Begay will keep hazing the sea lions until the end
of May.

That’s when the sea lions leave the dam and head back down the Columbia River to the
Pacific Coast to breed.

Bringing a Fish Back From the Brink

  • The American Shad became so rare that hatcheries had to help restore depleted populations (Photo courtesy of the US Fish and Wildlife Service)

A million year old cycle of fish migration almost came to an end in the waters off of the nation’s capital. But a monumental conservation effort has brought them back from the brink. Sabri Ben-Achour explains:

Transcript

A million year old cycle of fish migration almost came to an end in the waters off of the nation’s
capital. But a monumental conservation effort has brought them back from the brink. Sabri Ben-
Achour explains:

I bet you can’t recognize this sound.

It is the sound of a female shad – it’s a type of fish – having its eggs squeezed out into a metal
bowl.

“In the bowl, it looks like applesauce.”
That’s biologist Catherine Lim. We are on a boat in the middle of the Potomac, 20 miles south of
Washington DC, harvesting and fertilizing shad eggs. Lim picks up a male shad and gives it a
squeeze.

“Yeah, he sprayed out there.”

She mixes the brew around and adds water.

“We’ll bag them up and send them to the fish hatchery.”

This is all part of an effort to restore the population of the American Shad. For millions of years,
the large silver-iridescent fish have swum in from the Atlantic and up the rivers of the East Coast
every spring to spawn. They return to the same place where their lives began, guided by a
unique geological odor that seeps from the earth and mountains that feed each river.

Once upon a time – only a century ago – these fish were so numerous they turned the water silver
and made rivers move.

At least that’s what Jim Cummins says, he’s a biologist.

“On the Susquehanna, there were so many of them they created a wave as they came up the
river, a standing wave.”

On the Potomac they fueled entire industries. According to newspaper reports, Washington DC
exported 4 million barrels of salted shad every year in the 1840’s.

“The wagons would come into Georgetown were so heavy that they crammed up the city – I think
it’s the first report of gridlock in Washington.”

The fish fed more than just commerce – they nourish everything from crabs to dolphins. Bald
Eagles actually evolved to time their egg laying early, so their chicks would hatch just as the Shad
and their relatives appeared in the river. And then came overfishing, dams, and pollution.

“In the 1960’s, there were times when the migratory fish came up to spawn in the area and met
that pollution, and hundreds of thousands of them died and made a stinking mess.”

The clean water act was passed in 1972, but by 1980, the fish were almost wiped out. A
moratorium on fishing at the time was too little too late. Water quality gradually improved as
waste water treatment plants were upgraded and aquatic grasses returned. But still, no Shad.

So Cummins began the Shad restoration project.

They had to use several nets – each hundreds of feet long – just to catch one fish. They got help
from fisheries and even elementary schools. Dams were fixed to let fish go around them. The
Shad population exploded.

At a boat house just outside of DC, anglers Steve Bocat and Louis Covax are enjoying success
that up until recently, few alive have seen here.

“It was great we had incredible fishing. I mean, between the two of us, we had, what, 50-60 fish
up to the boat?”

Another sign of success, a pair of Bald Eagles recently returned to the area following the fish –
the first in decades.

Some States Planning Wolf Hunts

Some states plan to let people hunt wolves. Rebecca Williams reports that’s happening because the US government is taking gray wolves off the federal endangered species list in two places:

This decision means states in the western Great Lakes and several Rocky Mountain states will have control over wolves.

Some states are calling wolves a protected nongame species.

For example in Michigan, a wolf can only be killed if it’s attacking people, pets or livestock. But in other states – like Idaho and Montana – there are plans for a hunting season for wolves.

Jonathan Lovvorn is chief counsel for the Humane Society of the United States. His group and several others are planning to sue.

“Essentially what we’re worried about is that this is basically going to be a declaration of open season on animals that have been protected for decades.”

The federal decision to take wolves off the endangered species list could be overturned in court. That happened last fall.

If the decision sticks, then the Fish and Wildlife Service will be keeping an eye on wolf populations for at least the next five years.

Leaving Something Out on Earth Day?

Earth Day has grown from its counter culture roots. Now there’s a lot of green talk on Main Street. But as Mark Brush reports, the founder of Earth Day might think we’re leaving something out:

In the last several decades, concern about the environment has shifted from college campus protests to board room discussions. There’s a lot more awareness about environmental issues. And the administration in Washington D.C. is much more receptive. That has Earth Day organizers pretty excited.

The man credited for founding Earth Day is the late Senator Gaylord Nelson. He probably would’ve liked all this talk about a green future. But in a 2003 speech recorded by C-Span – the Senator said there was an important topic being left out of the conversation:

“The ultimate key to sustainability is population.”

He acknowledged that taking on population control is a tough thing to do for politicians. But if they’re really serious about taking on environmental problems, he said they’re going to have to get up the courage to talk about population.

Hard Times for Honeybees

Beekeepers are continuing to lose their honeybees. About a third of many beekeepers’ colonies have been dying mysteriously each year for the past several years. Rebecca Williams reports researchers think they’re getting closer to an answer:

Honeybees have had some bad luck.

Researchers think there are a couple of things hurting the bees all at once.

They think bees’ immune systems are being weakened.

Maybe because of pesticides. And maybe because bees aren’t getting the variety of food sources they need.

Bees normally collect pollen and nectar from many different plants. But when they’re used on farms, they’re just visiting one kind of plant.

And then on top of that, bees appear to be getting hit by a virus.

Maryann Frazier is a honeybee expert at Penn State University.

She says, until researchers can figure out exactly what’s going on, she expects beekeepers to keep losing a lot of their bees.

“I think what we’re at risk of, more so than the bees dying out, is the beekeepers giving up and not continuing to truck their bees all over the country.”

Beekeepers use honeybees to pollinate about a third of our food supply.

Commercial Fishing Gets Failing Grade

A new study out in the journal Nature grades countries on their ocean
fishing practices. Rebecca Williams reports even the top countries are not
getting a passing grade:

The US, Canada, and Norway are some of the countries doing the best job.
That means they’re fishing in a responsible way.

But they all come in at 60%. That’d be a D, maybe a D-plus.

Tony Pitcher is the main author of the study.

“Wasn’t very encouraging actually that even the top scoring countries were
not really that good. So it wasn’t anything to write home about – we were
at the top but it wasn’t a great field. At the bottom end some countries
were just disastrous. More than half the countries didn’t even pass the
40%.”

Countries are getting bad grades because there’s a lot of over-fishing going
on. There’s illegal fishing. And there’s a big problem with nets and traps
getting lost. They can snare marine mammals, birds and fish.

Tony Pitcher says it’s not always easy to know where your fish came from.
But he says you can look for a blue and white label when you’re shopping.
It’ll say Marine Stewardship Council on it.
