Water managers
sound alarms
Basin’s snowpack is only 53 percent of normal

Even if Idaho receives twice its normal precipitation
between now and spring, it probably won’t make up deficiencies in the
snowpack that were left from an unusually dry fall and winter.
South-facing slopes that were bare
Monday received a carpet of snow Tuesday. But water managers fear spring
snows will be too little and too late.
With each passing day this winter, the state’s
percentage of average snowpack numbers have dropped as winter storms
continued to skirt to the south.
The Big and Little Wood river valleys posted 53 percent of
normal water content Monday. That’s 4 percent lower than early January’s
percentages.
All of Idaho’s other river basins show similar low water
content measurements in their snowpacks.
South facing slopes in the Wood River and Sawtooth valleys
were bare Monday, and though there are still about two months of the
winter season left, the state’s water managers are beginning to sound
alarms.
"Are we okay? Probably not," said Dick Larsen,
Idaho Department of Water Resources spokesman. "We’re not going to
be in very good shape this year. Some of the snowpack levels we’re
talking about now are reaching low figures we haven’t seen since the ‘60s."
Snow level at the Ketchum Ranger
District was only 20 inches Monday. Seasonal total so far is 48.5 inches.
The highest mark recorded at the site was 203 total inches in the winter
of 1982-83.
Larsen said much of the state’s snow this year has
fallen at low elevations, not in the mountains where it usually melts off
gradually into summer.
"The snow that’s there is, in many cases, down
low," he said. "That means it’s going to come off early. We
need to see a change in something. The trouble is, we’re running out of
time."
According to the Natural Resources Conservation District’s
Web site, snow water content levels across the state range from 45 percent
to 75 percent of average and summer streamflow forecasts range from 50
percent to 75 percent of normal. And that’s assuming that a near-normal
amount of precipitation falls through the remainder of the winter, Larsen
pointed out.
The Big Wood River drainage is forecast to be among the
lowest flowing rivers this spring, at 42 to 55 percent of average flows.
Also included in that range are popular boating rivers
including the Payette and Snake River through Hells Canyon.
"As a result of the lack of high-elevation snow,
water users will see streamflows return to base levels earlier than
normal," the Web site reports.
Another way of tracking winter snowfall is through
municipal snow removal budgets.
Ketchum city administrator Jim Jaquet said the city
budgets $175,000 for snow removal each year. Two years ago, the city spent
$182,875 on snow removal, exceeding the budget by nearly $8,000.
Last year, the city spent $80,000 on snow removal, but as
of Monday, Ketchum had spent only $19,886 for snow removal this winter.
"But it’s important to remember you can spend a lot
of money in a short amount of time if we do get some snow," Jaquet
said.
Sun Valley Water and Sewer District manager Jack Brown
said he will have to wait and see what happens, but a water conservation
program, similar to what was implemented last August in the city of Sun
Valley, will probably come into play again this summer.
"It just depends entirely on the weather and the
underground aquifer," he said.
In addition, this winter’s low snowpack is beginning to
concern wildfire experts.
The snowpack is a primary factor in predicting what kind
of fire season is ahead. When snow melts in the spring, it provides
moisture for forests and grasslands. Without enough snow, dry conditions
could again invite fires comparable to last year’s.
"One of the cards has already pretty much been dealt
to us, and that is the snowpack," said Rick Ochoa, staff
meteorologist for the National Interagency Fire Center in Boise.
"Conditions may improve a little, but it’s unlikely that the West
will get back to normal snowpack by springtime."
