hile this program is made up of 

 individual actions, it will be implemented 

 through a structure and process that will en- 

 sure that the region receives the best possible 

 return from its investments. We are commit- 

 ted to the concept of "adaptive management," 

 which means that we treat some actions as 

 experiments designed to gamer knowledge as 



well as effect a change. Through careful 

 monitoring and evaluation, we will judge 

 which of our actions are most effective and 

 which ones fall short of our expectations. 

 Effective measures can then be continued, and 

 ineffective measures modified. 



Our program identifies a number of key 

 biological uncertainties and recommends 

 methods to address them. The program is

The Status of 

 Snake River Salmon 



In 1991 and 1992, Snake 

 River runs of chinook 

 and sockeye salmon were 

 listed under the federal 

 Endangered Species Act. 

 These charts are based on 

 fish counts at dams. Note 

 that the sockeye run is on 

 a different scale, given its 

 extremely low numbers.
