 Fourth Avenue bridge in the city of Yakima o It leads to two mill ponds, 

 from which a channel returns the water to the river. This ditch or flume 

 is not being used at present^ the water for the mill now being supplied by

Taylor Ditch takes off on the west bank approximately 2 miles above 

 the town of Selah, Washington and has a capacity of 27 c.f.s A rock wing 

 dam shxrnts water into the ditch, which was screened in 1938, 



Pomona Dam of which only remnants are left, is located approximately 

 106 miles above the mouth of the Yakima River and midway between the mouths 

 of Wenas and Selah Creeks o This dam was built so long ago that it is 

 difficult to obtain data on it. The structure is now owned by the Cascade 

 Lumber Company of Yakima, Washington, who report that they bought it from 

 the Yakima Boom Company in 1919., They further state that the dam was 

 evidently built to store water which was used to float logs down the Yakima 

 River to the saw mills. The dam has not been in use for over 30 years » 

 Older residents along the river have stated that this dam together with the 

 Sunnyside Dam (before it was laddered) were important factors in the early 

 decrease in the numbers of fish in the Yakima River because both structures 

 blocked part of the runs from their former spawning grounds for many years,

 upstream. It has a capacity of 140 c.f»s and was screened in 1938o 



Roza Dam locate^ approximately 115 miles upstream is one of the 

 more recent structures on the Yakima River, having been built in 1940 by 

 the Bureau of Reclamation. It is a concrete structure having a crest length 

 of 220 feet and a drop of over 20 feet. A fish ladder is located at the 

 east end of the dam.

 and is supplied with water by a diesel operated pump. The intsJce is 

 protected by a panel screen. 



The Stone-McGaff Ditch System takes off from a small side channel 

 135 172 miles upstream. The ditch loops for about one-half mile and is 

 joined by a drainage ditch before it returns to the river. The five 

 lateral diversions are equipped with screens which force fish to con- 

 tinue on through the main ditch back to the river. 



The Demon Mill Ditch originally took off from above a log wing dam 

 on the west bank of the river 136 1/2 miles upstream. It had a capacity of 

 12 CofoSo, and passed through a conduit under a dyke and supplied several 

 small irrigation ditches, as well as the mill. Several years ago the mill 

 was torn down, the dam was removed, and the ditches are now supplied by a 

 new intake located one-half mile downstream. The intake and the small 

 laterals are unscreened.
