Even really small hydro is not so green.  PGE's Centerville Powerhouse 
outside of Chico is rated at 5.8 MW.  As we all know that is a misnomer 
since during the critical low water period of summer, it rarely produces 
more than 2 MW.  When you you realize that prior to 1992 the minimum 
flow in the prime salmon holding and spawning areas was 20cfs in normal 
years and 10 in dry years, Centerville was a major fish killer for a 
paltry amount of power 
(http://buttecreek.org/documents/SpringRunNumbers.pdf).  Even today PGE 
struggles to maintain temperature in the low flow section (now with a 
40cfs normal year and 20 cfs dry year flow since 1992) because they try 
to squeeze out a few more KW's.  2002 and 2003 saw major fish kills 
(7000 and 11,000 prespawn endnagered salmon) that were characterized as 
natural loss due to high temperatuere.  Never mind that PGE controls the 
temperature in the low flow section.  Recent temperature data from the 
relicensing of the project show great benefits to shutting down the 
Centerville Powerhouse (at least during summer) and running all the 
water down the creek.  Please join me in requesting PGE to shut down the 
Centerville Powerhouse and let the creek run free.  We have nearly 
20,000 endangered spriing run salmon  this summer and they will be hard 
pressed to make it thorugh the summer with only 40cfs.  Normal summer 
flow ranges from 80 to 120cfs.  PGE would like to spend 40 million to 
replace the powerhouse which would buy a nice solar generating plant 
anywhere.  For more information on Butte Creek visit www.buttecreek.org
