In December of last year, High Country
News ran a news report about the severe drought then
plaguing the West. Ski slopes were brown, wildfires were still
burning in California and New Mexico, and weather forecasters were
calling for an ultra-dry Western winter. By the time the issue hit
the streets, those streets and everything else were buried in snow,
and it didn't stop falling 'til spring. Storms pounded much of the
West Coast, with especially heavy rain and snow in the Northwest;
high country roads were repeatedly closed in the Rockies; and 36
people had died in avalanches in the U.S. by the end of April.
Now, some parts of the high country are still trying to
dig out from one of the heaviest winters on record (more snow fell
in the Rockies May 1), and those in the low country are gearing up
for floods. Thanks to an above-average snowpack in the mountains,
the rivers in the upper Colorado River Basin are running strong.
All that water, says the Bureau of Reclamation, will push Lake
Powell's levels up by 50 feet, meaning the reservoir will be closer
to being full than it has been since 2002. But even so, it will be
far below capacity. When the reservoir reaches its midsummer peak,
the white bathtub ring on Powell's sandstone cliffs will still be
some 60 feet high. Then the ring will start growing again, as extra
water is released from the dam to generate juice for the
Southwest's air conditioners and to give the depleted Lake Mead a
bit of a boost.
If forecasts are to
be believed, Powell will continue to drop after that. A recent U.S.
Geological Survey report found that even modest warming from
climate change could dry up the Colorado River. Faced with the
report, Utah Division of Water Resources director Dennis Strong
told the Deseret News he's not too worried:
"We're fairly confident the water supply is not going to crash.
It's not going to stop flowing immediately."
Perhaps
scoffing at models and forecasts is the wisest thing to do, given
the wacky weather the region has experienced over the last several
months. In mid-April, for example, a winter storm dumped up to
three feet of snow in Colorado's San Juan Mountains, closing a
major highway. A few days later, huge winds swept across the
region, dumping red dust all over that new snow (speeding up the
snowmelt) and fueling two wildfires in Colorado, one of which
killed three people.
For a week, at least, avalanche
season coincided with wildfire season, and the idea that the
weather, or even the climate, can be predicted was thrown out the
window.
