I will be in Yellowstone during the first week of June. I have been there before and I'm fairly familiar with the waters, but all of my previous visits were in September. I can imagine that the water conditions are very different in June, almost like a different place.

I have studied the fishing regulations on the park site, and I'm aware that the general fishing season opens the Saturday before I will be there, but there are many, many listed exceptions to the general rule. I have also reviewed the "Great Rivers" section on this site, but I still have questions.

Obviously, spring runoff could make some of the waters I have fished look like new streams. Can anyone give me advice on what streams are open to fishing *and* not blown out by spring runoff? What about effective flies (my September fishing has been dominated by hoppers and other terrestrials)? What's the weather like there in early June?

Many thanks.
