Streambed Siltation 
Thirty-three stream-bottom samples were taken in 1951 by forcing the 
open end of a number 2 can horizontally into the gravel with the top 
side of the can as near the top of the gravel surface as possible. 
The samples were separated into four size classes: (1) over one-half 
inch; (2) 0.0489- to one-half inch; (3) 0.0098- to 0.0489-inch; and 
(4) smaller than 0.0098-inch. 
A gravel sampling tool was constructed in 1955 to permit gravel sampling 
to a depth of approximately 10 inches. The tool was eight inches in 
diameter and constructed of heavy metal (fig. 20). The tool is driven 
vertically into the gravel, a shovel inserted under the lower end, and 
the entire sample removed and placed in containers. Sixteen gravel 
samples were obtained from Maybeso Creek in 1955. Separation has not 
been made of these samples to date. 
The accurate sampling of stream bottom gravel to determine its content 
of fine material is a difficult task. The sampling tools used to date 
have not been entirely satisfactory. Large rocks, presence of bedrock, 
and swift, deep water make it difficult to obtain samples in many 
desired locations. A considerable amount of the fine material in the 
sample is lost, as it is washed out in the water trapped in the sample.
