YELLOWSTONE NATIONAL PARK, Wyo. (AP) -- A heat wave has warmed the Firehole River to as much as 82 degrees, killing hundreds of rainbow and brown trout.

Park officials noticed the kill Friday. Yellowstone spokesman Al Nash said temperatures above 73 degrees can be stressful or even fatal for trout.

He said the trout died within the previous three days.

Meanwhile, park officials enacted voluntary fishing closures at several areas because of the stress that warm water places on fish.

"We have a strong, involved, responsive user group here," said Nash. "We know that people come here because of the world-class fishing opportunities. We know how important it is to them and we know they'll join us in protecting this resource."

He said the current advisory is earlier and more widespread than in years past.

"I am not aware that we've involved this many rivers and creeks before," he said.

In northern Yellowstone, the advisory applies to the Gardner River below Osprey Falls; Lava Creek below Undine Falls; Lamar River below Cache Creek; all of Slough Creek; Soda Creek below Amphitheater Creek; and Yellowstone River below Seven Mile Hole.

On the west side of the park, the advisory applies to the Madison River, the Firehole River and to the Gibbon River below Gibbon Falls.

In southern Yellowstone, the advisory covers the Bechler River below Ouzel Creek; Fall River below Rainbow Falls; Mountain Ash Creek below Union Falls; Proposition Creek; Boundary Creek below Dunanda Falls; Robinson Creek; and the Snake River below Six Mile Ford.

What trout is native to the firehole? I'm amazed any fish can survive with all the thermal features spewing hot water in there. Hopefully some of the trout were able to run up the smaller, cooler feeder streams.

The Firehole is a crazy river. You can stand in one spot and it will feel like a hot tub. Move upstream 10 feet and it's back down to the 50s. Not sure what fish are native to it. I think I remember reading that the Firehole had no native fish at all at one time.

This was supposed to be year 4 for my back-country trip into the third meadow of Slough for a few nights. Not sure if I'll use that permit now.

The previous messagage was correct, both the rainbow and brown trout were stocked after the Park was opened. That's why there are no whitfish in the firehole above the falls.

I fished Wyoming much of last week, every river was MUCH lower and warmer than normal. This is going to be a brutal water year in the West. Time to conserve, oh wait, that will never happen, right?

Yeah, that's true. My guess would be at that time was when the caldera was molten lava... ;)

I am all for conserving water. I think that is why my lawn is dying. But I don't think conserving water will help the free flowing streams that rely on snow pack and water tabel high in the mountains. We neither take water from those streams nor put water back into them. It could help the reservoirs and tail waters though.

True, I was talking more for here in UT regarding conserving. It is sad to see those high elevation waters so warm and low.

I fished a small stream on the north slope of the Uintas a few weeks ago (mid June and usually the peek of the runnoff) and it was lower than it was when I fished it in mid July last year. I am worried about what it will be like in Late August.
