Hundreds of dead ducks discovered

DENVER - Almost 200 dead ducks have been found in a chlorine basin at a wastewater treatment facility.

An engineer first noticed several distressed ducks on site January 2nd, and then a week later, the staff discovered a pattern; hundreds of ducks dead in the water.

The Division of Wildlife and U.S. Fish and Wildlife are investigating, as lab tests are being performed in Fort Collins to find a cause to the problem.

For the past 20 years, hundreds of ducks flock to the warm water at this plant, but this is the first time the staff has noticed such an ominous scene.

?It's not unusual at all to have ducks here. The ducks come every winter, but we just don't see ducks die,? said Steve Frank, spokesperson for Metro Wastewater Reclamation District.

Maintenance workers at the plant have a sound gun firing off blank shots each half hour to keep the ducks away from the water, until the root of the problem is confirmed.

Workers are also skimming the water to find any remaining ducks.

Several of the surviving birds sit in cages and towels, with their feathers no longer waterproof, possibly suffering from hypothermia.

The plant increased the amount of chlorine in the water in December, but the staff says there?s no connection.

?When we increased the chlorine dosage we didn't notice any additional ducks, dead or alive, when we decreased it, we didn't notice any change either,? said Frank.

The staff plans to put a net over the basin to keep birds out of the water.

Lab results are expected within the next few weeks.

Why did they increase their chlorine dosage a few weeks ago?

Dead duck mystery widens

By Todd Hartman, Rocky Mountain News
February 5, 2007

<!-- /byline --> A weeks-old mystery over dead ducks at the Metro Wastewater Reclamation District plant in northeast Denver has widened. Dead ducks have been discovered in at least two other locales in the region.


A state Division of Wildlife spokeswoman said Monday that deceased ducks showing evidence of malnutrition and degraded waterproofing ? leading to death from hypothermia ? have also been found at the Northglenn wastewater plant and at a lake within a residential development near the 9000 block of E. Mississippi Ave. in southeast Denver.


At and around the Metro wastewater plant, the total number of dead ducks had climbed to 418 as of Monday morning.


Officials at the facility also announced that dead or injured ducks have been found along the South Platte River, both upstream and downstream of the Metro plant at 6450 York St. in northeast Denver.


Investigators have ruled out avian flu, Metro officials said. Experts have also examined the ducks? organs for disease, but found none, said Jennifer Churchill, a spokesman for the Division of Wildlife?s northeastern Colorado region.


"We?ve mostly just found things it?s not." Churchill said. "We know it?s not avian influenza, it?s not avian cholera. We?re doing a test for botulism, but don?t think it?s that." Ducks have been sent to both a state veterinary lab in Fort Collins, as well as a lab affiliated with the U.S. Fish and Wildlife Service in Oregon.


In almost all cases, the species affected were northern shovelers, Churchill said, with a few cases involving gadwalls.


Mallards were not affected, she said. The cases reported in Northglenn involved 30 to 40 ducks, and about 22 ducks at the Breakers Resort in southeast Denver.


The long run of cold weather could be connected to the deaths, Churchill said, but that?s only a theory. Ducks are used to handling all kinds of weather, but it?s possible a food source has become unavailable to the animals. Furthermore, there?s some evidence the deaths have decreased with a dose of warmer weather in the last few days, she said.


"The deaths of these ducks continue to puzzle us all," said Steve Rogowski, director of operations and maintenance at the Metro wastewater facility, in a statement issued this morning. "We are working with the Colorado Division of Wildlife and the U.S. Fish and Wildlife Service to try to find the cause."
Metro workers are also trying to rescue stricken ducks.


"We?ve placed an emphasis on recovery of any sick ducks that we find," Rogowski said. As of today, Metro employees had turned 84 sick or injured ducks over to two DOW-approved rehabilitation centers, officials said in a statement.


Water quality scientists with Metro found "a number" of dead ducks as they walked along the South Platte last week, from upstream of Metro?s plant at 64th Avenue and York Street to the river?s confluence with Clear Creek.
It's not clear that anything at the wastewater plant is responsible. "We have seen duck carcasses upstream of the plant ... (investigators) saw plenty of them along the river, enough to make you say whatever's happening is not just happening at Metro. That's what it would lead me to believe," said Steve Frank, a spokesman for the facility.


"We hope we can get this problem resolved soon. Protecting the environment, including wildlife, is among our top priorities," added Rogowskii.
Metro is the primary water treatment facility for the Denver area, serving 1.5 million people and treating about 130 million gallons of wastewater per day.

Avian flu ruled out in Denver-area duck deaths

DAILY NEWS STAFF REPORT
February 5, 2007

DENVER - Avian flu has been ruled out as the cause of death of about 375 ducks at a Denver-area wastewater treatment plant, officials said Monday.

The Metro Wastewater Reclamation District said it is still trying to determine what caused the deaths.

Steve Rogowski, the district's director of operations and maintenance, said the state Division of Wildlife ruled out avian flu as the cause.

Rogowski said Metro employees have turned over 84 sick or injured ducks to two rehabilitation centers approved by the state and an unspecified number of ducks have been given to wildlife officials for testing at the state's veterinary lab in Fort Collins.

Dying Ducks a Mystery in Denver

DENVER --

Ducks are a common site at the Metro Wastewater Treatment plant in Denver, but what's happening to them is anything but.

Workers have found 418 dead ducks since the beginning of January, 19 on Monday alone. Officials say tests show the water is basically normal and the facility is not doing anything new or different.

Eighty-four sick ducks are now being cared for at places like the Greenwood Wildlife Rehabilitation Sanctuary in Longmont.

The ducks show no clinical signs of disease but workers say their feathers are hard and crusty. They believe a contaminate of some kind is causing the ducks to lose their water proofing. The ducks become water logged and are dying of hypothermia. But so far no one knows what is causing this to happen.

The Colorado Division of Wildlife confirms today this is not the avian flu.

The Greenwood Wildlife Rehabilitation Sanctuary is providing care for more than 40 of the ducks. The facility is asking for donations.

More than 400 ducks have died at a wastewater-treatment plant in north Denver since the beginning of the year, and now dead ducks are appearing elsewhere along the Front Range.

Re: Denver: Hundreds of dead ducks discovered

Just curious- whether the workers have been given anti-virals as precaution- until more information is forthcoming. .
