The last run of silver salmon that was observed to enter 

 the stream occurred in October, 1929* A small number of these fish 

 probably still appear© 



In 1938 the Columbia River Investigation made an attempt to 

 determine the size of the Chinook run in the Tucannon River* A 

 counting weir was installed at a point 2 miles above the mouth, but 

 recurrent flash floods washed it out on several occasions, preventing 

 an accurate count* However, it was shown that the run had been 

 depleted to a negligible size. Only 2U Chinook salmon were observed 

 to pass through the weir, and later a careful check of the stream 

 failed to disclose any spawning activity* It was reported that a 

 total of 26 Chinook salmon were taken by sports fishermen during the 

 same season* 



The Tucannon is apparently of little value as a salmon pro- 

 ducer at present* However, it has excellent potential value, and 

 could support a good run if provisions were made for the passage of 

 fish over existing obstructions, and all diversions were adequately 

 screened to prevent the destruction of downstream migrants* 



2A* Kellogg Creek *-— (February, 1935} Suomela and Burrows*) 

 Kellogg Creek enters the Tucannon River at Starbuck, k miles above 

 the mouth* The stream is small and intermittent, and of no value 

 to migratory fish* 



2B. Smith Hollow Creek *— (February, 1935; Suomela and 

 Burrows.) Smith Hollow Creek enters the Tucannon River about 8 

 miles above the mouth* The stream is small and intermittent, and 

 of no value to migratory fish* 



2C* Pataha Creek * — (April 28, 1937; Suomela and Burrows*) 

 Pataha Creek enters the Tucannon River approximately 11 miles above 

 the mouth* The stream is about 35 miles long. At the time of 

 observation it was discharging about h c.f.s. It was reported that 

 the stream nearly always becomes dry during the summer* There are 

 no runs of migratory fish into Pataha Creek, and it is of no potential 

 value to them. 



2D* Tumalum Creek *— (June 18, 1935; Suomela and Shuman.) 

 Tumalum Creek enters the Tucannon River approximately 32^ miles above the 

 mouth* It is a small stream, and of no value to migratory fish* 



2E* Cummings Creek *— (June 18, 1935; Suomela and Shuman*) 

 Cummings Creek enters the Tucannon River approximately 3U miles above 

 the mouth* The stream is about 12 miles long, of which the lower 6 

 miles were surveyed* It is too small and steep above the terminus 

 of the survey to be of value to salmon. At a point 2\ miles above 

 the mouth the stream was 10 feet wide and flowing at a rate of about
