Columbia River Steelhead Numbers for Perspective
The 2009 summer steelhead run in the Columbia Basin was far better than average. Counts are incomplete for 2009, as there are still nearly two months left in the year. However, in most years few steelhead pass over Bonneville Dam in November and December. At 602,306 it is doubtful that we will beat the 2001 total of 633,464. The best news is that at 171,538, the 2009 run of wild summer steelhead is the largest ever recorded over Bonneville Dam. The numbers below are offered for your contemplation.
The chart below draws no political or biological conclusions. It is only a table of raw data collected at one Columbia River dam for 71-years (about the length of one average human life). It does appear that within this short period of time that steelhead run numbers fluctuate significantly from year to year. Probably over a longer period of observation they would fluctuate even more. It would also appear that during the last ten year period we are on the high end of these fluctuations. We thought you would like a share of this good news.
The period of 2000-2009 saw 3,989,868 steelhead cross Bonneville Dam.
This compares to the ten year period of 1990-1999 when 2,180,512 steelhead passed through the same fish ladders. Trends might be seen more clearly when these numbers are compared to even earlier ten year periods. The 2000-2009 period has over twice the number of steelhead as any ten-period 1940-1979. Wild steelhead were not counted prior to 1994. The 2009 wild steelhead count exceeds 85% of the total steelhead counts prior to the 33-year period before 1970.
