The Eas tion Dam is located just above the town of Easton^ Washing ton,, 

 and approximately 186 miles above the mouth of the Yakima River* It is a 

 ooncrete structure built in 1929 and has a crest lenj^th of 248 feet and a 

 drop of about 60 fee to It has a 20 pool fish ladder on the north siAm 

 that is reported to be kept in operation only during, the irri{',ation L^ea^one 

 During the winter months such discharge as is permitted is from two ap3r= 

 trares at the base of the dam, and the dam is then a barrier to f isho Tha 

 fish ladder is steep and not a particularly good one, the pools being small 

 for salmon passage » The drops between the pools are high, requiring fish 

 to J'.jmp from one pool to another, and fish occasionally have observed to 

 jianp completely out of the ladder. This fishway should be rebuilt so that 

 it will operate effectivelyo A few salmon have been seen above the dam by 

 survey parties j, and fish have been reported passing the dam on several 

 oocasloni. o 



The Kittitas Diversion Canal more popularly known as the High Line 

 Canal^ takes off at the south end of the Eas ton Dam but latei' oTossei. 'the 

 Yakima River' in the vicinity of Horlick, Vfashingtono It diverted 50C oof«s 

 in i929„ 1,080 cfoSo in 1936, and over 1,300 cfoS after 1937« Its total 

 length is 76 miles o It is protected by a stationary one-half inch spaced 

 bar screened at the intake™ 



The Lake Keechelus High Control Dam is located 198 miles above the 

 mouth of the Yakima Riverj, and approximately 12 miles above Eas ton Damo 

 It is a rock faced, earth and gravel fill dam, 70 feet high, with a 

 crest length of 6,500 fee to Water from above the dam is normally spilled 

 through a conduit or tionnel 12 feet wide, and hence the dam is impassable 

 to fisho There were originally two small lakes at this site that were 

 accessible to fish and supported a blueback population« Storage first 

 began above a crib dam in 1906, and above the present dam in 1914, although 

 the reservoir was not completely filled until 1920* Because of the great 

 fluctuation m the water level, sometimes over 60 feet, a fish ladder over 

 this dam has not been considered practical «
