2. Releases for the Hoopa Valley Tribe's Boat Dance Ceremony (which is held in odd-numbered years) went from Aug 18 through 25, 2023.
3. Times reflect releases from Lewiston Dam, and it is assumed that it takes approximately 12 hours for the water to get to Pigeon Point and 20 hours to get to Cedar Flat. This is a good rule of thumb, though the actual flow travel time is flow dependent (the higher the flow, the less time it takes). Here are some approximate observed numbers:
| Lewiston Release | Time to Pigeon Point | Time to Cedar Flat |
|---|---|---|
| 500 cfs | 13 hours | 24 hours |
| 1000 cfs | 12 hours | 20 hours |
| 1500 cfs | 10 hours | 14 hours |
| 3000 cfs | 9 hours | 13 hours |
