River at Tiverton, subject to more detailed design studies of the 

 structures and their effects on navigation, pollution and fisheries. 

 The estimated cost of these barriers, based on optimum founda- 

 tion conditions, is $69, 000, 000. Some revision of this estimated 

 cost may be expected upon completion of the detailed design 

 studies which the Division Engineer recommends. Under the most 

 unfavorable foundation conditions the estimated cost of these 

 barriers is $109, 000, 000.
