The Greenbelt is mostly opened again, except for a few critical areas. Recreational use of the river is still closed or restricted due to debris (snags etc.) and floating not allowed. Stream flows have gone down but not enough to clear and resume recreational use.
The fireworks display has also been moved from Ann Morrison Park to Expo Idaho (Western Idaho Fairgrounds) this year due to the high water conditions and loss of Greenbelt portions. High heat is a big concern and only safe and sane non-aerial fireworks are allowed in the opinion of state officials, no rockets and devices with flames traveling in excess of 10-12 feet I believe it is and as always no firecrackers. In the past you could buy them in Idaho but not use them there. which is often ignored and led to a devastating wildfire in a residential area of the foothills last year.
