From The Denver Post:
Full reservoirs can mainly be attributed to good snow and reservoir accumulations the previous two years, according to the NRCS. Snow accounts for most of the state’s year-round water supply for drinking and household use, agriculture and recreation. Officials were concerned by the warm, dry weather of early April, but recent mountain storms improved the situation. “These late-season improvements in the snowpack will have positive impacts on this summer’s runoff and water supplies in these basins,” according to a statement today from the federal agency, which measures the state’s snowpack.
