high, and is not a barrier to fish except at extreme low water stages. 

 There are no fish protective devices. 



The Harper Valley is 1 to 2 miles wide, and largely in alfalfa 

 grain, and pasture. The valley is bounded by low hills having a 

 sparse cover of sage 



(U) Canyon below Juntura t- 



Above the Harper valley the river extends for 32 miles through 

 a steep, v-shaped canyon 100 to liOO yards wide The canyon is 

 bounded by steep, rocky foothills 20O-U00 feet high having a sparse 

 cover of sage. There is no cultivation in this section. The liver 

 has an average width of 60 feet and a moderate gradient throughout. 

 The river bed is composed of two-thirds medium and small rubble and 

 one- third silt, ^here are numerous shallow riffle areas, but due to 

 the heavy layer of silt deposited throughout it was judged that not 

 more than 10 percent of the bottom should be classified as suitable 

 spawning area. There are numerous small resting pools, but the ex- 

 tremely sparse marginal vegetation, principally sage, provides no 

 stream cover. The water temperature was 69.0°F. at the lower end of 

 the canyon The river flow just below the confluence of the north fork 

 was 685 c.f.s. at the time of observation. 



There is a small unscreened irrigation diversion located 1 mile 

 above the upper end of Harper valley. The ditch was carrying about 

 2 c.f.s. at the time of the survey. The temporary, 1 foot high rock 

 wing dam was considered passable to fish. 



The Harper dam and reservoir and the Vale-Oregon Irrigation Canal 

 are located 11 miles above the town of Harper This dam and reservoir 

 constitute the diversion works of the Vale Project, constructed by the 

 U. S. Bureau of Reclamation for the control and diversion of water im- 

 pounded above in the 7 f 'armsprings and Agency Valley reservoirs. The 

 diversion canals in connection with the Harper dam have a carrying 

 capacity of 60i* c.f.s. At the time of the survey the Vale-Oregon canal 

 was withdrawing 200 c.f.s. The dam is 17 feet high, 702 feet long, 

 and is a barrier to fish. There are no fish protective devices in connection 

 with the diversions. 



(5) Juntura Valley and headwaters i- 



Proceeding upstream, the main Malheur River extends for 2 miles 

 across the lower end of the Juntura valley, and then extends for 20 

 miles through a steep canyon 1/U mile wide up to the Riverside dam 

 and the Warmsprings reservoir. This canyon is bounded by low foot- 

 hills having a sparse cover of sage and a few small jack pines. There 

 is no cultivation in this section except for a narrow strip of pasture
