Other than that Matt, how was your trip?
I've been making an annual 10 - 11 day trip ever since 1995. When I was still working it was always the first 10 days in August due to a plant wide shutdown. By August the PMD's were gone and all we had were Tricos and a cinnamon caddis and we had great fishing. After I retired in 2005 I have gone between June 23 and July 23. Up until my 2010 trip the fishing was really great with days of at least a dozen 17" - 21" fish with at least a couple 22" during the trip.
Since 2010 the fishing has fallen off (IMO) and both the boating and wading angler pressure has increased significantly. In 2011 I canceled due to high water, in 2012 Tony and I went out and the fishing was horrible. It was the first year when I saw there were far fewer rising fish. I felt bad because I had raved about the river to Tony and it had been very good up through 2010. Ever since 2012 I've had less than stellar fishing. 2014 was really poor for me and I said to myself that I was done with the Missouri and even shipped my frameless pontoon boat back home. Well by January 2015 I wanted to go out again and was pretty excited but when we got there the fishing was really off. It was an early PMD year and by the beginning of June there were good numbers of bugs and guys were finding lots of rising fish and the river was uncrowded. Also guys who were willing to watch a bobber float down the river were boating 20 - 30 fish a day.
I arrived on July 04 and I would say there were at least 200 drift boats, rafts, pontoon boats and recreational floaters on a six mile section of the river. I was lucky to catch 3-4 fish a day. Admittedly I don't float from 6 - 10 like my partner and two friends who always go out at the same period. They had many good evenings with 6 - 8 fish each plus the 4-5 they would catch during the morning float.
To sum it up it was my worst trip in all my Missouri River trips. I left my pontoon boat there on the chance I might go back again someday but I am already planning my 2016 trip and it won't be to the Missouri.
Edit: Due to limited lodging in the Wolf Creek and Craig areas you must make your next years plans many months, even a year, in advance or you won't be able to book a room in the entire prime time window from June 15 - July 15.
It is also the same situation with booking your flight. Those seats get booked quickly and by mid January many flights are filling up. Therefore you are booking a trip before the winter snows have really begun. If it is a high snow pack year you could be blown out. Any flow of more than 6500 cfs pretty much ends all wade fishing and I can't afford $75 a day drift boat rentals (2 guys split the $150 price) Conversely in a low snow pack/spring rain condition you could have flows under 3000 cfs which warms the water quickly and hastens the growth of aquatic grasses. Pretty much every fish you hook once the weed growth has bloomed will run into the grass and either the tippet will break or the hook will pull out. During my 2013 trip I lost at least 80% of my hooked trout in the grass.
