Snowpack in the mountains that feeds the Colorado River is slightly above the long-term average, welcome news in the drought-stricken Southwest.
But experts say it's too early to predict how deep the snow will get or how much of it will turn into water that makes its way into Lake Powell in Utah and Arizona.
April is the key time for predicting how much water will flow into into the lake from the snow melting in the Rocky Mountains. The bulk of the snow has fallen by then, and the runoff has begun.
On Tuesday, the snowpack was 104 percent of normal in the Upper Colorado River Basin. That includes the western half of Colorado, the eastern half of Utah and smaller portions of Wyoming, New Mexico and Arizona.
