artificial propagatioa by the Leavenworth hatchery of the Fish and 

 Wildlife Service and the majoritj; of the resulting fingerlings are 

 liberated into Wsnatchee Lake to aid in maintaining and increasing 

 the abundance of this vaiiiable species^ 



The 'Wanatchea supports a good run of steelhead trout which 

 epawTi in the spring in the upper section of the river and its 

 tributaries,, Cutthroat^ Dolly Varden^ rainbow trout, whitefish, 

 and kokanee are also preaent and are extensively fished in the 

 Wenatohee River watershedo Obstructions and diversions on the 

 Wenatchee River are as follows ? 



The Gunn Irrigation Daa and Diversion is located 6 miles up- 

 stream"o Ifhe oSSTTs built of concrete, has a drop of 1 1/2 feet, 

 and is on the north channel of the iriver at this point. The 

 diversion has a capacity of 40 CofoSo and was screened in 1938» 



Trie Jones-Shotwell Ditch 12 miles upstream has a capacity of 

 25 c ,773 o rt~ms provi3ed~wTth a rotary screen in 1938. 



The Pine Flats Irrigation Ditch 16 1/2 miles upstream diverts 

 4 cofTsT^nd is screened. 



The Dryden Dam formerly owned by the Paget Sound Povrer and 

 Light CoiTipahy~andr'th9 Wenatchee Reclamation District, and now 

 operated by a Public Utility District„ is located 17 miles up- 

 stream and has alwaya been a serious obstruction to the upstream 

 passage of anadromous fish. 



There are three sections of -chis dam; an "upper dam" extending 

 about two-thirds the vmy across the river, a concrete wall extending 

 downstream about 100 j.'ar.iSj, and a "lower dam* continuing to the 

 opposite shore. The '''upper dam** is about five feet high while the 

 •"loir/er daiifis approximately eight feet high. Both dams are constructed 

 of wooden timbers and have wide downstream aprons. Both dams were 

 equipped with small wood fishways. The fish-way at the '"tapper darf'was 

 replaced with a concrete pool=type fishway in 19476 The fishway at 

 the "^x owe r" dam has been virtaally out of operation for a number of 

 years. The situation at Dryden is aggravated insofar as the pas- 

 sage of fish is conoerned owing to the diversion of water at this 

 dam for pawer and irrigation purposes. The power plant is nearly 

 a mile downstream from the dam so that the intervening reach of the 

 river is nearly dry at low water flows, and fish have difficulty in 

 ascending che river at st;ch times. 



The Dryden Power and Highland Canal takes off at the north end 

 of the dsmTand has' a "capeTcily "of 1,37*8 c.foS. A power house located 

 nearly a mile below the intaKe returns a large portion of the water 

 to the river, and the remainder is carried by the Highland Canal to 

 the Wenatchee Reclamation District.
