8 c.f.s. The water temperature ranged from U7°F. to 53°F. The 

 gradient is moderate in the lower 5 miles, and becomes steep in 

 the upper section. There are numerous shallow riffles and small 

 pools throughout the section surveyedo It was estimated that 

 there were 23,000 sq. yd. of medium and small rubble constituting 

 7U percent of the stream bed in the section surveyedo A large 

 part of the stream bed provides excellent spawning area. 



Two small irrigation diversions were found on Cummings 

 Creek. The first, located about 1/2 mile above the mouth, was not 

 in use at the time of inspection but had a capacity of about 2 

 c.f.s. The second, located about a mile above the mouth, was with- 

 drawing about 2 c.f.s. There were no fish protective devices* The 

 wing dams in connection with these diversions were not barriers to 

 fish, 



Cummings Creek formerly supported a good Chinook salmon 

 population, but there has been no Chinook run in recent years. A 

 good spring run of steelhead trout still enters the stream, and 

 there is also a large population of resident rainbow trout in the 

 upper section* The stream is of excellent potential value to 

 salmon* 



2F* Watermelon Creek * — (June 18, 1935 J Suomela and Shuman*) 

 Watermelon Creek enters the Tucannon River approximately 39 miles 

 above the mouth. It is a small, short stream, and of no value to 

 salmon* 



2G. Grub Canyon Creek ,— (June 18, 1935; Suomela and Shuman.) 

 Grub Canyon Creek enters the Tucannon River approximately Ul^ miles 

 above the mouth. It is a small, short stream, and of no value to salmon* 



2H* Little Tucannon River , — (April 28, 1937; Suomela and 

 Burrows*) The Little Tucannon River enters the Tucannon River approxi- 

 mately Uii miles above the mouth, and extends for about 6 miles* It 

 has a steep gradient with many cascades, and a stream bed composed 

 chiefly of large rubble and boulders. The discharge was about U c.f.s. 

 at the time of observation* Because of its small size and lack of 

 good spawning area the stream is of little possible value to salmon 

 or steelhead* 



21. Panjab Creek* — (June 19, 1935; Suomela and Shuman*) 

 Panjab Creek enters the Tucannon River approximately U6 miles above 

 the mouth* The stream is about 8 miles long, of which the lower k 

 miles were surveyed up to the mouth of Turkey Creek* Above this 

 point the stream was flowing less than 5 c.f.s,, and was too small 

 and steep to be of more than slight possible value to salmon* The 

 stream was 19 feet wide at the mouth, and was discharging about 60 

 c.f.s* The gradient is fairly steep and the velocity is high, being 

 3-1; feet per second throughout the section surveyed. The water tempera- 

 ture ranged from U5°F to U9°F, There are many fast riffle areas, and
