The data below is the SWE (Snow Water Equivalent) for the Galena SNOTEL site.
The number at the far left is the year.  Data is listed for the first of each month from January
through June.  Galena Summit is the SNOTEL that is closest to the headwaters of the Salmon.
Although there is no direct, scientific connection between Galena's SWE and Salmon River flow,
the data can provide an approximate perspective concerning how the upcoming year's Salmon River flow might evolve.
Simply compare any given year's SWE data with that year's river flow above.
