Trends in the timing of snowmelt and associated runoff in Colorado were evaluated for the 1978?2007 water years using the regional Kendall test (RKT) on daily snow-water equivalent (SWE) data from snowpack telemetry (SNOTEL) sites and daily streamflow data from headwater streams. The RKT is a robust, nonparametric test that provides an increased power of trend detection by grouping data from multiple sites within a given geographic region. The RKT analyses indicated strong, pervasive trends in snowmelt and streamflow timing, which have shifted toward earlier in the year by a median of 2?3 weeks over the 29-yr study period. In contrast, relatively few statistically significant trends were detected using simple linear...
