Water Management Issues:

1.  The Hoopa Valley Tribe's Boat Dance Ceremony will not be held this year (they are held only 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 cfs13 hours24 hours
1000 cfs12 hours20 hours
1500 cfs10 hours14 hours
3000 cfs9 hours13 hours
