Yeah, blutski has it right. Quick bear rundown...
2007 - good year, ran above 300 for a while, ran for over a month
2006 - no runoff in spring, couple of boatable days during monsoon rains
2005 - Peak about 200, only a handful of boatable days
2004 - No runoff in spring, day or two of monsoon flows
2003 - Peaked at 275, ran for a couple weeks
2002 - no runnable flows
2001 - no runnable flows
2000 - no runnable flows
1999 - peaked at 660 and ran for about two months with a monsoon spike too.
so in the last 9 years, its had three seasons with decent flows for a couple of weeks or more. 99 was the last time it ran big, 2003 was the last time it really got above scrapy levels.
