(Radio Iowa) – Tourism is down in the Iowa Great Lakes after heavy rains and high water forced the implementation of issue boating restrictions. The Executive Director of Vacation Okoboji , Kylie Zankowski, says summer business is important to the area.

Zankowski estimates flooding has decreased tourism by 40 to 60 percent.

Zankowski says some hotel occupancy was cut in half during the Independence Day holiday. Juli Redig has been coming to the Iowa Great Lakes from Minnesota since she was the age of her grandchildren. And they saw very few boats on the water during a visit to Arnolds Park due to a five mile and hour speed limit put in place to preserve the shoreline.

Redig says she’s still making the most of her family’s vacation. They brought their pontoon boat to enjoy the water slowly. Zankowski she says there’s hope as water levels and quality continue to improve. She says the Arnolds Park amusement area and other attractions, along with the food, and entertainment give tourists other options.

(Radio Iowa) – Iowa State University researchers say a sugar molecule they’ve found in the mammary glands of cattle is the so-called receptor that transmits highly pathogenic avian influenza. Professor Todd Bell, in I-S-U’s veterinary pathology lab, says their study could lead to measures that prevent the spread of bird flu, which has infected more than a dozen large herds of dairy cattle in northwest Iowa in recent weeks. “Our team across the street in the vet diagnostic lab kind of figured out the ‘what’ which is we have influenza in the mammary tissue of dairy cattle,” Bell says, “and now here in pathology, we’re trying to understand the ‘why’ and look at mammary tissue to understand why this virus is getting in.”

Researchers in Ames are working under the hypothesis that milking machines may be involved in spreading the virus from cow to cow.  “There’s multiple different routes that influenza can infect different species, but we want to look at that as a potential route,” Bell says. “What we’re trying to do is not only understand maybe how externally the virus is getting to the mammary gland, but more specifically, we’re trying to understand how and why this virus can infect mammary tissue, which prior to this, had been unreported in mammary glands of cattle.”

If they can track the transmission of the virus to milking machines, Bell notes one possible solution to stop the spread is quite elementary. “If a virus is present on milking machines and then is getting into mammary tissue as you attach those milking machines,” Bell says, “one way to potentially stop that would be to disinfect or clean those milking machines prior to milking.” Milk sold in grocery stores and by other retailers is pasteurized, and the F-D-A and dairy industry are stressing that there’s no threat to the milk supply because the pasteurization process neutralizes viruses. Bell agrees. “Everything that we’ve seen so far from a research perspective does say that,” Bell says, “that pasteurized milk is very safe, that heating to that extent renders the virus inactive.”

Bird flu isn’t usually deadly for cows, but it’s often fatal for birds. Since the start of the outbreak, the U-S-D-A says more than 97-million birds have been affected, while commercial poultry flocks where the virus is found are typically euthanized. The study was published in the July edition of Emerging Infectious Diseases, the Centers for Disease Control and Prevention’s peer-reviewed journal. Thirteen of its 14 co-authors are from I-S-U, including researchers and faculty from across the College of Veterinary Medicine.

(Radio Iowa) – The Iowa Natural Resources Commission gave final approval Thursday to antlerless deer quotas that include a drop in the number of does that can be taken in western Iowa. The D-N-R held hearings on the issue and commissioner K.R. Buck of Denison says there was support for the cutback at the hearing he attended. “I think there was 35 or 36 at our meeting. I think if everybody was asked to raise their hand they were willing to give up a doe season through the paid season and archery for two years,” he says. “They see the devastation that our deer population has taken in western Iowa.”

Buck says the lack of deer in the area is concerning. “Our deer population last two years has been wiped out. I mean it’s amazing,” Buck says. The D-N-R’s Tyler Harms oversees the state deer populations and told the commission one of the reasons for the big drop in western Iowa’s deer herd is overhunting. “It’s very obvious that overharvest over an extended period of time from really the mid 2000s to the early 2010s contributed to the population decline,” he says. Harms says disease outbreaks in the deer herd are also an issue. -H-D outbreaks in western Iowa starting in 2012,” Harms says. “Since then there’s been at least five severe outbreaks statewide, which certainly hasn’t helped the situation over in that part of the state.”

The antlerless deer licenses will be cut from 200 to 0 in Cass County, from 250 to 0 in Harrison, Monona, and Pottawattamie counties, from 150 to 0 in Page County, from 200 to 150 in Montgomery County. Some western Iowa counties, including Woodbury and Worth, already had no antlerless deer tags available.

The D-N-R has some new meetings about deer management underway now which they say will help shape how they manage the deer population in western Iowa through the next five years.

DES MOINES, Iowa — Late-night TV icons with Iowa ties will be immortalized in butter at next month’s Iowa State Fair. Johnny Carson, who was born in Corning, and Des Moines native Steve Higgins will be in the Agriculture Building’s cooler next to the wildly popular butter cow and another special guest — “The Tonight Show” host Jimmy Fallon. State Fair butter sculptor Sarah Pratt and her team will also make a butter version of the sky glider to celebrate its 50th year.

Fallon, known for his on-air impressions, will get his own impression in butter at the 2024 Iowa State Fair. Fallon will be sculpted alongside the Tonight Show’s announcer, producer and Des Moines, Iowa, native Steve Higgins in celebration of 10 years with Jimmy Fallon as the host of the show.

Another Iowa native will also be featured in butter – longtime Tonight Show host Johnny Carson. Johnny Carson lived in Corning, Avoca and Red Oak as a child. Carson took over the Tonight Show in 1962 for a run that lasted three decades.

The butter cow, along with butter versions of Higgins, Carson and Fallon, will be featured alongside an iconic sky glider chair as the main Sky Glider celebrates 50 years in 2024. All of the sculptures will be on display in the John Deere Agriculture Building 9 a.m. to 8 p.m., during the Fair, August 8-18.

The butter cow has been an annual attraction at the State Fair since 1911. Sarah Pratt of West Des Moines was named the fair’s fifth butter sculptor in 2006 after 15 years as an apprentice to Duffy Lyon. Companion sculptures of the butter cow have been a tradition since at least 1996 when Grant Wood’s famous “American Gothic” painting was immortalized. Last year’s fair featured iconic Iowa athletes Jack Trice, Kurt Warner and Caitlin Clark.

The 2024 Iowa State Fair annual parade kicks things off Aug. 7 in downtown Des Moines.

(Radio Iowa) – The latest Drought Monitor report for Iowa is dramatically different than it was one year ago. One year ago 100 percent of Iowa was either in drought or abnormally dry conditions. The latest Drought Monitor map shows just Scott County and a small part of Clinton County now show abnormally dry conditions. That amounts to less than one percent of the state.

State Climatologist Justin Glisan says the last time Iowa had no abnormally dry areas was in early May of 2020. The state has been free of actual drought conditions since late May of this year – which stopped four-years of drought conditions.

DES MOINES, Iowa [WHO-TV] — The Iowa State Fair is cancelling two attractions amid concerns over Avian Influenza infections in dairy cows. The Milking Parlor and the I Milked a Cow Experience will not be a part of the fair this year to prevent the spread of avian flu. So far this year there have been at least ten confirmed cases of bird flu in Iowa dairy herds.

Jeremy Parsons, CEO of the Iowa State Fair, said safety is the fair’s first concern. “I think for the average fairgoer you’re still going to see dairy cattle at the Iowa State Fair,” Parsons said. “The dairy industry is important in Iowa agriculture so we’re still showcasing that, just showcasing it a little different in terms of no milking parlor and no hands-on experience of I Milked a Cow that many fairgoers have done over the years, so just a chance to still walk through the barns, see the cattle, honestly just trying to keep the livestock safe quite frankly as we showcase Iowa agriculture.”

(Ames, Iowa)  – The Iowa Department of Natural Resources says the City of Audubon has agreed to pay an $8,000 fine for repeatedly expelling too much ammonia nitrogen in its wastewater that flows to the East Nishnabotna River. The Iowa Capital Dispatch reports, according to a recent DNR order, Audubon violated its ammonia limits in nearly every month of 2021 and 2022 and in several months of 2023.

Elevated levels of ammonia can be toxic to fish and other aquatic life and can deplete oxygen in water. The city has said its pollution woes were the result of large amounts of contaminants from a truck stop that pipes its wastewater to the city’s treatment facility. Waspy’s Truck Stop opened about six years ago and has a truck wash that is used to clean the insides of animal trailers. That debris was believed to be the source of the excessive ammonia levels in Audubon’s treated wastewater. The DNR also fined Waspy’s $8,000 this year and said it had violated its pollutant limits — for ammonia nitrogen, waste solids, oil and grease — more than 500 times.

The truck stop has installed barriers to collect the manure and help prevent it from being discharged to the treatment facility. Audubon’s public works director was not immediately available to comment for this article, but he has said the situation was improving. The DNR order noted that Audubon was warned multiple times that it was exceeding its contaminant limits but that it failed to expeditiously remedy the problem.

Treated wastewater from the city flows through a creek to the East Nishnabotna, which was polluted downstream in March by a large fertilizer spill near Red Oak. The spill killed nearly all the fish and other aquatic life in about 60 miles of the East Nishnabotna and Nishnabotna rivers.

(Radio Iowa) – It’s been almost four years since a powerful derecho blasted across Iowa, causing some 11-billion dollars damage, and the rebuilding of our landscapes is still far from complete. The storm’s winds of up to 140-miles an hour wiped out millions of trees and a grant program is offering funds to help communities recover and replant. Ellie Jones is the Iowa D-N-R’s community disaster recovery coordinator, and she’s partnering with Trees Forever. “We lost a lot more trees than we can replace within a couple of years,” Jones says. “Between urban and non-urban areas, we lost over seven-million trees. We’ve had this grant program going on pretty much since the year after the derecho happened, but unfortunately, with the amount of funds that we have available and the sheer amount of recovery that needs to be done, it’s probably going to – hopefully – continue for the next 10 years as well.”

The Community Forestry Grant Program offers grants of between 500 and 10-thousand dollars to purchase and plant trees suitable to Iowa. “This is a grant that’s for public landowners,” Jones says. “Unfortunately, we’re not able to work with private landowners, especially with this grant, but if you are a public entity or work on behalf of a city, you can apply and you have to be in one of the 27 counties that were in the governor’s proclamation of disaster.” Unlike with previous grants, she says matching funds are -not- required from communities with this effort. Cedar Rapids was one of the worst-hit communities, losing more than half of its tree canopy to the derecho’s winds on August 10th of 2020. Jones says trees help to purify our waterways, and they filter out carbon and other harmful pollutants from the air. Trees also help to offset what’s known as the urban heat island effect.

“In cities, because there’s so little green space, they tend to be a lot hotter. Since we have these really high temperatures in our cities,” Jones says, “people are more prone to heat-borne illnesses and things of that nature. When we lost a lot of these trees in our urban areas, you’re making that problem worse and we’re not getting the benefits that those trees provided.” The deadline to apply is August 26th.

(Des Moines, Iowa) – State regulators have taken action against three men they say share responsibility for illegal fires that torched 10 large chicken confinement buildings last year near Villisca. The Iowa Capital Dispatch reports one of the men, Tyson Means of Villisca, has agreed to pay a $10,000 fine, according to a recent Iowa Department of Natural Resources order. Two others, Shawn Gohlinghorst and Darrel Schipansky, were issued violation notices, but no orders regarding them have been publicly released.

State law generally prohibits the deliberate burning of buildings and requires their debris be taken to a landfill, but there are exceptions for agricultural buildings. In this case, Villisca had annexed the property, and burning the buildings had additional requirements, such as gaining approval from the local fire chief. That didn’t happen, according to the DNR. The building fires were ignited simultaneously about 3 p.m. on June 29, and they burned for hours. Each building was 50 feet wide and 728 feet long. Iowa DNR Senior environmental Specialist Kristi Burg said “There’s no way you would have had enough fire departments and water nearby if it got out of control.” The Villisca fire chief became aware of the fires about seven hours after they began and decided “it was too big to be put out,” the DNR order said.

Several rural homes are located nearby, along with a site for storing and distributing liquid fertilizer. The property lies about a mile west of residences and businesses in town. Montgomery County Emergency Management Coordinator Brian Hamman said the smoke and glow from the fire was visible for miles, and residents in four different counties made emergency calls to report it. Hamman said the men burned the buildings after recent rainfall, and that the fires did not stray. “From my point of view, there was nothing dangerous,” he said.

Schipansky owned the property, and Gohlinghorst and Means later bought it on contract. They razed the site with the intention of growing crops on the land. The men had also neglected to inspect the site for asbestos. The DNR tested samples of the debris and found no asbestos, but “a thorough asbestos sampling could not have been conducted since the buildings had been completely burned,” the department’s order said.

Gohlinghorst and Means rid the property of the remaining building debris in September and October 2023 and disposed of it at a landfill, the order said.
