Walter posted a thorough update over at his site. Check it out.
Here are some key takeaways for the PFS operations area:
- Good winter snowpack is now melting furiously due to near-record temperatures (in the 80s in Livingston), which has everything except the Firehole and Lower Madison blown-out now.
- Anticipate a brief spring season for the Firehole, Gibbon, and Madison inside YNP, as well as the lower Madison. The Madison basin inside and outside Yellowstone Park has the lowest snowpack in our operations area and it is melting quick.
- The Yellowstone River outside YNP is likely to fall into fishable shape during the last week of June, with the Salmonfly hatch at the same time.
- Waters across the northern part of Yellowstone Park will begin falling into shape around June 15-20, with the Yellowstone in the Grand Canyon and the Gardner first. The Black Canyon of the Yellowstone will come into play around June 25 or so, while the Lamar System will probably come in around or after July 4.
- Slow fishing in late afternoon may occur in late July and August due to warm water temperatures, particularly on low-elevation sections of the Yellowstone east of Livingston, but the Yellowstone has the highest snowpack in our ops area, so except for a few days of “early on, early off” when it’s hot and sunny, we anticipate no other problems. At this time, we do not anticipate any “hoot owl” restrictions on any of our July-September waters. Restrictions are likely on the Jefferson, lower Madison, and other areas we never fish (and no one else fishes) in mid-late summer.
