2015 wildfire season a record-breaker


EarthSky

Worst recorded years for U.S. wildfires are 2005, 2006, 2007, 2011 and 2012. This year has already joined that list, and wildfire season is still going strong.

The ongoing drought in the U.S. West is not helping the wildfire situation in 2015.  Current info about 2015's drought in the U.S. here
The 2015 wildfire season in the United States has already broken records. So far this year, more acres of land have burned as of mid-September than the total annual amount in 2011, which was the 4th worst year for wildfires at least since the 1960s. So will this year be the new fourth worst, third worst, second worst, or worst wildfire year since then? Read on, and take a guess.
The National Interagency Fire Center in Boise, Idaho, publishes a ton of useful statistics on wildfires that are critical for helping state and federal agencies manage the flames. These records date back to the 1960s.
The chart below, created with the National Interagency Fire Center data, shows that the worst years for wildfires in the U.S., since these records began being kept, were 2006 (9,873,745 acres burned), 2007 (9,328,045 acres burned), 2012 (9,326,238 acres burned), 2011 (8,711,367 acres burned), and 2005 (8,689,389 acres burned).
Already as of September 18, 2015, 8,821,040 acres of land have burned across the U.S., and this number exceeds the total number of acres burned for 2011. Hence, 2015 has already earned a spot as the 4th worst year on record, and the 2015 wildfire season is still going strong.

Nevada Marina Deemed Safe Despite 100K Fish Kill





Most locals reacted like Rick Dinoso when he first heard that all the fish in the Sparks Marina were dead — an estimated 100,000 trout, bass and catfish.
"All the fish don't just die," said Dinoso, 37, an assistant manager at a nearby tavern who grew up in Sparks.
"That's a lot of fish," Wayne Weaver said Friday as he walked the 2-mile loop trail around the 77-acre, man-made lake with wife, Dee. "That's a lot of recreation lost."
Scientists say the massive fish kill was caused by a dramatic drop in the water's oxygen content, which they say is not all that uncommon. They believe it was triggered by a weeklong cold spurt in December when lows hovered near zero at the former gravel pit converted into a marina 15 years ago along Interstate 80 just east of Reno.
Though testing is incomplete, state wildlife and environmental officials are convinced there's no danger to humans or animals. There's been no sign of any contamination like the pollutants that leaked into the pit in the 1980s from a petroleum tank farm across the highway, they say.
Despite those assurances, city officials have been forced to respond to concerned citizens. Most worry whether it's safe to let their dogs in the water.
"It's not good for the fish obviously, but the water quality itself is great and there's no health or safety issue," city spokesman Adam Mayberry said. "Other than fishing, there's no indication you can't do anything else out there that you have always been doing."
Sudeep Chandra, a limnologist at the University of Nevada, Reno known for his research at Lake Tahoe, agrees.
"I really don't think it is other contaminants, it's just the low oxygen," he said. He said it likely occurred when the oxygen-rich warmer waters on the lake's surface quickly cooled, sinking to the bottom of the lake and causing a violent "turnover" of the waters.
A hot, dry summer may have contributed by spurring growth of oxygen-sucking algae, he said.

Mystery of Nevada lake where 100,00 fish died off in a single MONTH

  • Fish at Sparks Marina near Reno, Nevada, died from lack of oxygen
  • Biologists can't determine what is causing the loss of oxygen
  • 100,000 trout, bass and catfish washed up dead on the shores of the lake
By Associated Press Reporter

State wildlife officials are trying to figure out why all the fish have died in a northern Nevada marina where the stocked fishery has flourished since the man-made lake was created nearly 15 years ago.
An estimated 100,000 trout, bass and catfish have died over the past month in the Sparks Marina along U.S. Interstate 80 east of Reno, apparently the result of a dramatic, unexplained drop in dissolved oxygen levels, Nevada Department of Wildlife spokesman Chris Healy said Wednesday.
Scientists say a bitter cold snap could have caused oxygen-poor waters to rise from the old rock quarry's bottom to the surface, but they don't understand what sparked the massive die-off.
All of the fish died in the lake at Sparks Marina in Nevada - 100,000 in a single month

Fish biologists confirmed low oxygen levels caused the death of an estimated 3,000 fish in one corner of the lake in mid-December, but Healy said they thought at the time that the event was localized and of limited impact.
Since then, they've been unable to detect any live fish in the 77-acre lake. Numerous dead fish have been removed from the lake's shoreline, and Healy said it's likely the rest sank to the bottom.
'The 100,000 dead fish figure is something that is probably a pretty conservative guess,' said Healy, who estimates they've stocked close to 1 million adult fish in the lake since they started in 1998.

Pneumonia outbreak threatens bighorn sheep in California, Nevada

LOS ANGELES | Tue Jun 25, 2013 8:22am IST

(Reuters) - A pneumonia outbreak is threatening hundreds of bighorn sheep in California's Mojave National Preserve, and wildlife officials said Monday they see no promising options for saving the state's biggest herd or protecting a nearby population in Nevada.

The disease is believed to have killed 20 bighorn sheep during the past month in the 1.6-million-acre (650,000-hectare) desert preserve, which lies 50 miles southwest of Las Vegas, National Park Service spokeswoman Linda Slater said.

"I suspect that many more are infected," Slater said, adding that the entire herd, numbering as many as 300 animals, is in danger. "The biologists seem to be very pessimistic."

Potential options under consideration include shooting some or all of the remaining members of the herd in a bid to prevent further spread of the disease, or continuing to monitor the situation and essentially let nature run its course, wildlife officials said.

"There really are no good options," Slater said.

Episodic waves of disease have thinned bighorn herds for years. Fewer than 100,000 sheep are believed to roam the rugged mountain slopes of the West today, compared with an estimated 1.2 million head that inhabited the region at one time.

A series of nine separate outbreaks across five western states, including Nevada, in the winter of 2009-2010 claimed roughly 1,000 bighorn sheep, prized as game animals for the prominent curled horns of the adult males, or rams.

Description
It is day four of the Carpenter One wildfire on the back side of Mount Charleston near Pahrump and there is still no containment. A mandatory evacuation order for the Trout Canyon area was issued on Thursday afternoon. According to the Bureau of Land Management, 21 homes are affected. It is not known though if all of those homes are currently occupied. The latest estimate on the size of the wildfire is 1,250 acres. At one point, the BLM estimated the size at almost 2,000 acres but lowered that number later. The reason for the mandatory evacuation because changing weather patterns increased the likelihood of the fire moving towards the homes. A shelter is being opened at the Hafen Elementary School in Pahrump and the American Red Cross will be providing assistance.

Mount Charleston 'closed' as growing wildfire threatens homes





Fanned by increasing winds, a burgeoning wildfire began descending the east side of Mount Charleston on Thursday, prompting mandatory evacuations and sending cars full of residents and their possessions down the mountain.

The building winds made it difficult to fight the blaze encroaching Kyle Canyon, Las Vegas police spokesman Bill Cassell said. At 9:45 p.m., the fire was climbing the west side of Cathedral Rock.

The wildfire kindled by lightning Monday morning in Carpenter Canyon, on the west side of the Spring Mountains, has grown beyond the 1,250 acres reported before 1 p.m. Thursday and has crested the peak of Mount Charleston, officials said.

Multiple sources told the Review-Journal that the fire was descending the ridge between Griffith and Mount Charleston peaks. The Bureau of Land Management said late Thursday no reports of structure damage had been made. Officials did not update information about the size of the fire or exact location throughout the night.

Trout Canyon, near the original source of the fire, also was evacuated, and a shelter was set up in Pahrump for the residents of the 21 houses there.

Officials began evacuating Lee Canyon, which neighbors Kyle Canyon, late Thursday night.

“They told me to get off the mountain,” Rose Meranto, a resident of Old Town in Kyle Canyon said. “They just said don’t waste time and go. So I got my kitty cats and my son’s cats and I moved.”

About 500 people were affected by Thursday’s escalating rounds of evacuations. At 11 p.m., Cassell said officers were returning to the homes of those who were reluctant to leave and requiring them to do so as a matter of public safety.

“Mount Charleston is closed,” Cassell said.

It’s not known when evacuees will be allowed to return to their homes. It’s common in a blaze like this for evacuations to last seven to 14 days, Cassell said fire officials told him.

State routes 156 and 157 at U.S. Highway 95 leading to Mount Charleston have been closed, along with Trout Canyon Road at state Route 160.

No one is being permitted up the mountain.

“The fire reached the trigger point; burning embers are shooting out,” Cassell said.

A Review-Journal reporter in the Rainbow community on Mount Charleston witnessed flames twice as tall as the pine trees overlooking Kyle Canyon before they were obscured by smoke.

Sue Mowbray, a tourist staying in a Rainbow cabin with her children, said: “The sky was just bright red. I’ve never seen anything like this before.”

As Mowbray went down the mountain, she noticed people still at campsites. She left on her own at 5 p.m., before she was told about the evacuation.
