Fires and fishing in the Yellowstone heat

How hot has it been in and around Yellowstone this summer? Unfortunately, there isn’t a punch-line to end here, but instead two updates detailing how high temperatures and the lack of rain in recent weeks are affecting both fishing and fires.
Fires
As of today, there have been ten fires in Yellowstone so far this year. Most areas of the park have received minimal rainfall dating back to early June, and fire restrictions have been in effect in the park since July 3 (four out of the ten fires have been human-caused). Up to this point, all of the fires save one have been tiny, with only the still active Raven fire spreading across 20 acres. Firefighter numbers for this blaze have been limited, as it’s in the heart of grizzly country some nine miles east of Fishing Bridge, but the blaze is nonetheless over 75% contained. Conditions in Grand Teton to the south are similar, with heavy fire restrictions in effect as well.
All of this doesn’t mean massive fires are on the way, but conditions are prime for such an occurance. All visitor services, park entrances and park roads are open throughout both parks, but we’ll continue to update conditions here as temperatures continue to rise.
Fishing
Minimal snowfalls from this past winter combined with below average precipitation this spring and early summer have begun to take their toll on fish populations throughout the region. The combination of low flows, geothermal heating and high temperatures have raised water temperatures to sometimes deadly levels, and fish have been spotted floating along both Pelican Creek due east of Fishing Bridge and in the Firehole River.
How low are some of the rivers running? According to recent story in the Billings Gazette, last week the Lamar River near Tower Falls had about 27 percent of its normal flow for July 10 compared with records going back 67 years. And along the Firhole River, flows last week were lower than the previous record set in 1988.
To help the already stressed fish populations, park officials have asked that anglers not fish between noon and 6 p.m. on most streams below 7,000 feet. The advisory includes Gardner River below Osprey Falls, the Lamar River below Cache Creek, all of Slough Creek, Soda Butte Creek below Amphitheater Creek, the Yellowstone River below Seven Mile Hole, the Gibbon River below Gibbon Falls, and all of the Madison and Firehole.
