Water Management Issues:

1. The Hoopa Valley Tribe's Boat Dance Ceremony was not held this year (they are held in odd-numbered years, typically late August).

2. 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
