Water Supply Forecast Shows Record Snow in Northern Parts of West, Parched in Southwest

March storms increased snowpack in the northern half of the West but didn’t provide much relief for the dry southern half, according to data from the U.S. Department of Agriculture’s National Water and Climate Center (NWCC) in its April 2014 water supply forecast.

According to the Natural Resources Conservation Service (NRCS), most of Idaho, Montana, Wyoming, and northern parts of Colorado and Utah are expected to have near normal or above normal water supplies, according to the forecast.  Far below normal streamflow is expected for southern Oregon, California, Arizona, New Mexico, southern Utah and western Nevada.

Measuring the Value of Snow

A stormy February doubled the Mount Hood snowpack from five feet to ten – a relief for northern Oregon, which has been unseasonably dry. Hydrologists have told me about dramatic recoveries, but this is the first time I’ve witnessed it.

I recently joined Julie Koeberle, one of our hydrologists with USDA’s Natural Resources Conservation Service, to collect data that would be released in the March forecast from the agency’s National Water and Climate Center.

We snow-shoed out to the site and weighed the snow, and a local reporter tagged along to see how it’s done. Weighing snow allows surveyors to calculate the snow-water equivalent, in other words, how much water is in the snow. Light, fluffy snow contains less than dense, packed snow. Read more »

Limited water supplies are predicted in many areas west of the Continental Divide, according to this year’s second forecast by the National Water and Climate Center of USDA’s Natural Resources Conservation Service (NRCS).

Right now, snow measuring stations in California, Nevada and Oregon that currently don’t have any snow, and a full recovery isn’t likely, the center’s staff said.

USDA is partnering with states, including those in the West, to help mitigate the severe effects of drought on agriculture. Read more »

Year’s First National Water Forecast Predicts Limited Supply West of the Continental Divide

A limited water supply is predicted west of the Continental Divide, according to the Natural Resources Conservation Service (NRCS) National Water and Climate Center (NWCC) data in its first forecast in 2014.

The NWCC also predicts normal water supply east of the Continental Divide and will continue to monitor, forecast and update water supplies for the next six months.

Monitoring snowpack of 13 western states, the center’s mission is to help the West prepare for spring and summer snowmelt and streamflow by providing periodic forecasts. It’s a tool for farmers, ranchers, water managers, communities and recreational users to make informed, science-based decisions about future water availability. Read more »

NRCS Snow Surveyor Collects Vital Water Data, Lives Dream Job

Koeberle’s job carries her over mountains by helicopter and horse, snowshoes and skis. She has encountered grizzly bears, avalanches and wolves and visited ridges that few people have seen.

Koeberle is a hydrologist and snow surveyor for USDA’s Natural Resources Conservation Service (NRCS) and works on the agency’s snow survey team—a group of specially trained scientists who maintain snow gauges that are important to farmers, business owners and many other people in the West.

Once a month in winter and spring, snow surveyors from USDA’s Natural Resources Conservation Service (NRCS) head for the hills to measure the mountain snowpack. These trained observers ski, snowshoe or snowmobile to established snow measurement courses to record snow data the old fashioned way – by hand. Read more »
