number of Columbia River salmon is one tenth of what it was. Keep in
mind this estimate includes all runs of Columbia River salmon--spring,
fall chinook; coho; summer and winter steelhead; sockeye; and chum.
The number includes for both wild and hatchery produced salmon. The
number is for those salmon entering the Columbia River and does not
include natural and human caused mortality in the ocean. Post-1938
estimates come from the ODFW and WDFW annual Status Report.
For 1770, estimates come from a combination of sources including Chapman,
Craig and Hacker.
