I know from experience that parks like Yosemite have the full waterfalls & river in the spring & then come August they just about completely dry. Is it the same in August for Yellowstone? Or are Tower Falls, The Grand Canyon Falls & rivers pretty much full the whole year? I do not know how much of the Yellowstone water is from snow run off.

I also know the more still water, the more mosquito's. How are the mosquito's in Yellowstone in August? Thanks.

indicates that the water goes over these falls throughout the summer (none are listed as 'seasonal'), although the best time to see them is in spring.

"Just accept it now; no matter what month you visit Yellowstone Park there will be bugs. ... cool areas in July and August that have mosquitoes. If it makes you feel any better.......the deer flies are the worst."

The main thing that can dry up is the Mammoth Hot Spring Terrace. In dry years, it doesn't run at all. In many many trips I've never seen the waterfalls any drier than another year.

We've never had much trouble with bugs in Yellowstone--usually go in mid to late July. We've had terrible trouble just north east of there camping along the Beartooth Highway.

We were in Yellowstone in early September 2009 and the waterfalls and rivers were flowing pretty good. We've also been in Yosemite in the fall and seen the Yosemite Falls down to a drip. I'm sure spring is better in Yellowstone, but it's not going to be like Yosemite in the Fall.

I was just there the first week of August.

Mammoth was totally dry and I was talking to a ranger about Crystal Falls and he said the water was a bit lower there this time of year. Every other water falls seemed to be running heavy.

I didn't have an issue with bugs and didn't use the spray I brought with at all.

We were there in August 2 years ago, grand canyon falls was beautiful lots o water. Mammoth was pretty dry, the rangers said it had been drying up over the past 10 yrs or so.
