has a moderate gradient and excellent spawning areas. It is of some 

 possible value to migratory fish except at low water stages. 



13U-(U). Dry Creek . — (October Ik, 1°U0; Parkhurst and Frey.^ 

 Dry Creek enters the Wallowa River approximately 19 miles above the 

 mouth. It was UO feet wide near the mouth and discharging about 

 50 c.f.s. at the time of the survey. It is normally a small stream, 

 the high discharge being accounted for by the return flow from a large 

 irrigation diversion originating on the Wallowa River and joining Dry 

 Creek a short distance above the mouth. The gradient is moderate, and 

 the stream contains some excellent spawning area, but because of the low 

 natural flow in late summer above the irrigation return it was considered 

 to be of little possible value to salmon. 



13U-(5). Bear Creek . — (October 16, 19^0; Parkhurst and Frey.) 

 Bear Creek enters the Wallowa River near the town of Wallowa, approxi- 

 mately 22 miles above the mouth, and extends for a distance of about 

 2$ miles. It had an average width of 15-20 feet, and was discharging 

 about 1$ c.f.s. at the time of the survey. Gaging station records 

 indicate that the flow during the water-year usually ranges from a 

 minimum of about 6 c.f.s. to a maximum of about 550 c.f e s., with a 

 mean yearly flow of about 100 cf.s. (Water Resources of the State of 

 Oregon.) There are several small irrigation diversions in the upper 

 section of the stream. The gradient is moderate, and there are some 

 excellent spawning areas. Because of the low volume of flow at the 

 time of the Chinook salmon migration in July and August the stream is 

 of little potential value to this species, but it is attractive to 

 steelhead trout at higher water stages. 



13U-(6). Whiskey Creek . — (October 16, 19U0; Parkhurst and Frey.) 

 Whiskey Creek enters the Wallowa River approximately 2k\ miles above 

 the mouth. It is a small stream, discharging less than 1 c.f.s. at the 

 time of the survey, and is of no possible value to salmon. 



13U-(7). Lostine River .— (October 16, 19U0; Parkhurst and Fray.) 

 The Lostine River is one of the principal tributaries of the Wallowa, 

 and enters the latter stream approximately 26£ miles above the mouth. 

 It extends for a distance of about 30 miles, the upper part of the 

 course being through extremely rugged terrain. Its source is in Minam 

 Lake, at the opposite end of the lake from the source of the Minam River. 

 The stream had an average width of 3h feet, and was flowing at the rate 

 of 62 c.f.s. at a station 10 miles above the mouth on the date of obser- 

 vation. Gaging station records for the years 1912-13 and 192S-U5, taken 

 at the above station, show discharges ranging from a maximum of 2,5uO c.f.s. 

 in May 1913, to a minimum of 10 c.f.s. in November 1936. The average dis- 

 charge for 18 years was 175 c»f # s., according to U. S. Geological Survey 

 records. The gradient is moderate to fairly steep, with numerous shallow 

 riffles and an abundance of excellent spawning area. There are a number 

 of small irrigation diversions in the lower section of the stream. Most 

 of these withdraw about 2 c.f.s., and none is provided with fish pro- 

 tective devices. There is a domestic water supply dam 3| feet high
