Dear Congressman DeFazio: 



We are greatly disappointed that we were not allowed to testify 

 at your public hearing. The first public word appeared in the 

 Statesman newspaper on September 21st in Boise. 



We have been working on the Boylan Pipeline Concept since the 

 summer of 1991. I am enclosing copies of presentations I have 

 made to the Northwest Power Council and several other groups 

 responsible for fish passage on the Columbia River System. 



To date we have found no unsurmountable obstacle in using the 

 Boylan system. Recently Morrison Knudson Engineering in Boise 

 has joined us in drafting a proposal to test the systems. Oregon 

 State University and the University of Idaho are also working on 

 the proposals. 



If the proposal proves feasible, it would eliminate virtually all 

 of the impacts on other industries, plus predation on the smolt 

 by squawfish and other predators. 



One comment we got from all groups that looked at our original 

 proposal was "how are you going to get your hands on the smolts 

 before they reach the first dam"? We believe we have that 

 problem solved. We are working with the Sonalysts, Inc. out of 

 Waterford, Conn, who have been using sonic guidance for years to 

 keep fish out bf turbines, at Power plants and to herd fish for 

 other reasons. Each family of fish responds to a specific sound 

 frequency, through their ear structure. 



Once that frequency is found fish will not cross that sound 

 barrier. 



Currently Sonalysts is working with Morrison Knudson engineers 

 who are building the Boston Tunnel. Two or three times a day 

 Sonalysts herds the fish 1200-1500 feet away from the blasting 

 area and MK blasts away rocks and debris from the tunnel area. 

 To date they have found no fish mortality at the site.
