Water Management Issues:

1.  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 Cedar Flat 
500 cfs24 hours
1000 cfs20 hours
1500 cfs14 hours
3000 cfs13 hours

2.  The Hoopa Valley Tribe's Boat Dance Ceremony is not scheduled to be held this year (they are held only in odd-numbered years).

3.  The above schedule is based on information provided by the U.S. Bureau of Reclamation.
