CASPER, Wyo. (AP) — A week after Wyoming's snowpack showed signs of improving, snow levels have declined.

The Natural Resources Conservation Service in Casper said Monday that the snowpack statewide is 80 percent of average, down from 88 percent a week ago.

Last year at this time the snowpack statewide was 114 percent of average.

Now, there's just one basin that's above average, the Powder-Tongue.

Lee Hackleman of the NRCS says the lagging snowpack is concerning but thinks there could still be time to make up for the lack of snowfall, especially with big spring storms. He said the good news is that reservoir levels are still good because of last year's wet year.

There's no help in the immediate future. Some snow is expected in western Wyoming late Tuesday but it's forecast to be light.
