Dams and Their Impact Salmon and Smolts

by Edward L. Fisk
Idaho Statesman, August 24, 2007

The Statesman continues to call for breaching of the lower Snake River dams. And each year, it seems that more people are getting behind the idea. The consensus is that the dams and reservoirs are killing salmon smolts in such numbers that not enough smolts reach the ocean, grow and return to sustain our salmon runs. This makes the dams and reservoirs "the limiting factor." If this is true, then the limiting aspect should be amply evident in the yearly counts of adult salmon.

One could argue that the dams were limiting most of the time. Granted, but it is also possible they were not limiting clear back in 1947, especially if you take into account the recent research on ocean conditions of David Welch and the similar work of James Anderson.
