Both spring and annual flow peak magnitudes in-
creased in wet years in the south and west but re-
mained unchanged elsewhere. The increase of the
spring flow peak magnitude is most likely related to a
thicker snowpack and therefore an increase in spring
snowmelt whereas the increase of annual flow peak
magnitude is either related to an increase in spring
snowmelt or an increase of winter rain and snowmelt.
The timing of spring and annual flow peaks remained
unchanged between wet and dry years, except for
