Hi:

We're doing some work on salmon migrations on the Columbia River 
(Washington State). I have a set of data from an external agency where 
positions are recorded as river miles (miles upstream). Apparently, they 
used a US Army Corps of Engineers River Mile Index to estimate positions. I 
am wondering if anybody knows where I might find a coverage which shows 
this River Mile Index. Thanks in advance for your assistance.
