Narrative:
Three snowcourses had snow on them this month which is below normal.  Runoff up to
this point has been higher than last years values for the streams that have peaked but still below normal.
May has turned out to be another dry month with only .48" of precip. With the normal being 2".  This dryness
during peak runoff equates to more snowpack water going to satisfy soil moisture requirements rather than
overland flows.  Streams are showing a lower than expected runoff due to this major factor even though snowpacks
were close to normal.
