Lakewood (AP) - Statewide snowpack dwindled to 76 percent of average, with no major river basin at or above average, according to the Natural Resources Conservation Service.
The agency says the dip amid mild, warm weather means the state remained vulnerable to significant water shortages.
It says that across Southwestern Colorado, where snowpack is down to 60 percent of the 30-year average, only about half the average runoff is expected.
The South Platte, which provides water to the Denver metro area, was the closest to average at 99 percent of the 30-year average.
NRCS State Conservationist Allen Green says it remains to be seen how precipitation in April will shape up.
