Do you know your snowpack?

9 facts about Colorado snowpack: what it is, why it’s important and how we tell how much of it we have.

By Steve Snyder

You may have seen this map from the Natural Resources Conservation Service of Colorado. It shows how much snowpack we have in Colorado this year compared to normal. But what is normal? For that matter, what is snowpack, and what does it have to do with our water supply? Our Denver Water experts answer these questions and more in the slideshow below:

Snowpack news: San Luis Valley hit hard by storm — the Valley Courier

From the Valley Courier (Ruth Heide):

After unseasonably warm temperatures and extended periods with no precipitation, this past weekend began to make up for some of the winter the Valley had missed so far.

Weekend snowfall reports ranged from 8 inches in Alamosa to nearly a foot farther south in Conejos County and 39 inches of new snow at the Wolf Creek Ski Area.

As snow began to pile up throughout the day on Sunday , area schools started announcing closures for Monday. By late Sunday all of the public schools in the San Luis Valley had declared a snow day for Monday. Adams State University and Trinidad State Junior College also called off classes on Monday, and some businesses and governmental agencies were closed…

However, skies are expected to be overcast all week, and the chance of precipitation will increase from 10-20 percent midweek to 30 percent by Thursday night. Friday and Saturday will bring about 30 percent chance of precipitation , according to the National Weather Service. Temperatures will also remain colder this week, with high temperatures in the mid 30’s . The Valley will not likely surpass 40 degrees again until Saturday.

The San Luis Valley and surrounding mountains were under a hazardous weather watch through most of Monday, and avalanche warnings are in effect in the mountains and backcountry at least through noon today, Feb. 24. The

Colorado Avalanche Information Center issued a warning for the Sangre de Cristo,

Southern San Juan and Northern San Juan Mountains through midday Tuesday , due to the significant amounts of new snow and winds creating dangerous conditions in the backcountry of Colorado’s southern mountains. Wolf Creek Pass was closed on the west side for avalanche control for a time on Monday but had reopened by midday. Avalanche control was planned on Monarch Monday night.

All mountain and high Valley areas will have hazardous travel conditions because of the icy and snowpacked roads, and motorists are urged to use caution.

“Drivers are cautioned to drive slow and be patient,” City of Alamosa officials urged.

“Our crews are set to do their jobs,” Colorado Department of Transportation Executive Director Shailen Bhatt said. “We are asking for the same level of preparedness from drivers. We cannot stress enough the need for folks to know the conditions, prepare their vehicles with good snow tires and topped up fluids, and drive for the conditions.”

He added, “Travelers should check http://www.cotrip. org before heading out.”

Colorado State Patrol was busy responding to accidents throughout the recent snowstorm but accident statistics were not available by press time Monday. Most involved vehicles sliding off the road. CSP urged motorists to take it slow and stay off the slick roads unless absolutely necessary.

On the bright side, in addition to more powder at the ski area and a snow day for school children, this weekend’s snowstorm brought a boost to the area’s lagging snowpack. By Monday the snowpack had risen to 67 percent of normal basin wide, which still offers plenty of room for improvement.

Some areas of the San Luis Valley were showing more positive numbers. For example, Cochetopa Pass was at 134 percent of normal snowpack and Medano Pass at 100 percent, which bodes well for streams at the Great Sand Dunes National Park & Preserve this summer.

From The Mountain Mail (Brian McCabe):

The blue light, announcing 6 or more inches of snow, lit up on top of Tenderfoot Mountain Monday night following a weekend storm that dropped 17 inches of new snow at Monarch Mountain and 5-8 inches around Salida.

The fluffy, dry snow resulted in 0.55 inch of precipitation in Salida.

Monarch now has a mid-mountain base of 70 inches, and the new powder bumped the resort’s numbers for Monday.

“We definitely had higher numbers today,” Jessie Smith, marketing coordinator said. “School having a snow day helped as well.”

Salida schools canceled classes for a rare snow day.

“I’ve been here for 5 years, and it’s the first one I know about,” said Salida School District Superintendant Darryl Webb.

“I talked to school board member Kyle Earhart, who has been around for 9 years, and this is the first one he remembers as well.”

Webb said the school district doesn’t have a hard and fast rule for deciding when to call a snow day for the schools.

“We contact the county first,” Webb said, “and Evalyn Parks (district transportation director) and I will drive the roads early, to see what they are like, before making a decision.”

Webb said in the case of this snow day, they decided the night before after hearing the forecast for snow to continue falling through noon.

Webb said the district has extra days built into its calendar for just such days, so the students won’t have to make up any days at the end of the year.

“Unless we get a lot more snow,” he said.

The National Weather Service has forecast a hazardous weather outlook through the coming weekend for south central and southeast Colorado.

A new weather system will begin Wednesday evening and last through the weekend, bringing a chance of snow Wednesday through Friday and significantly colder temperatures Thursday and Friday.

The South Platte is key to the #COWaterPlan — The Fort Morgan Times

From The Fort Morgan Times (Sara Waite):

The South Platte Basin and Metro Roundtables, which collectively represent the South Platte River Basin, collaborated on a Basin Implementation Plan (BIP). The draft BIPs from each basin were released last summer; the final drafts are due in April.

The two organizations have been seeking public input on the draft South Platte BIP, offering a series of meetings and webinars in various locations throughout the basin.

A video produced by the group to give an overview of the water plan and BIP explains, “A good Colorado plan is a good South Platte plan.” The South Platte basin is a key economic driver of the state, with seven of the state’s top 10 agriculture-producing counties, as well as the Denver metro area and growing communities like Loveland, Greeley and Fort Collins that together account for over half of the state’s economic activity. The basin’s economy is also enhanced by environmental and recreational tourism — skiing, boating, fishing, wildlife viewing and hunting — and is home to the most-visited state parks and the eastern half of the Rocky Mountain National Park.

The South Platte Basin is a leader in water conservation efforts. “Long-standing efforts to conserve and reuse water in order to get the most benefit from available supplies has meant that by the time water flows out of our state, each drop has been used multiple times for different purposes,” the video states.

But a growing population base in the basin and statewide means municipal and industrial water demand could double before 2050, and outpace the state’s current water supply. Following current trends could mean drying up over half of the basin’s irrigated cropland in that time, a practice that, if overused, is “not in the best interest of the Basin nor is it in the best interest of the State.”

The South Platte plan calls for pragmatic solutions that are consistent with Colorado law and property rights. These include a wide range of strategies that could be used in various combinations to meet the gap: conservation and reuse; multi-purpose water projects that include municipal, industrial, recreational and environmental components; agricultural transfers, including alternative transfer methods; Colorado River Basin supplies; and storage projects.

The competing needs present enormous challenges, the BIP notes, and those challenges drive the solutions. Joe Frank, chair of the South Platte Basin Roundtable, has called for public feedback on the solutions outlined in the draft plan to meet current and future water needs.

Arkansas Basin Roundtable recap: Focus on agriculture

Basin roundtable boundaries

From The Pueblo Chieftain (Chris Woodka):

While its purpose is to find ways to fill the municipal water gap, the Arkansas Basin Roundtable wants to elevate the importance of agriculture. That was apparent in several actions at its monthly meeting this week.

The most obvious was the adoption of a statement proposed by Reeves Brown, a Beulah rancher and board member of the Lower Arkansas Valley Water Conservancy District, that stresses the irrigated agriculture to tourism, food production, recreation, environment, general well-being and the economy.

The roundtable also selected a rural advocate rather than a water utilities manager for a vacancy on its executive committee.

Finally, it demanded more details from El Paso County interests seeking a state grant to determine if it would ultimately encourage more dry-up of agriculture.

“I would like to give my thanks to the roundtable for supporting agriculture. This is an important issue,” Brown said.

Support came without objection after Gary Barber, a consultant who chaired the roundtable until becoming a consultant for it, detailed years of projects that aimed at reducing buy-and-dry of farmland for municipal supply.

Some of those projects included : A 2005 Colorado State University study that assigned per-acre economic value for farm crops.

A 2008 template for community considerations developed by roundtable members.

An economic report that pegged farm losses from the 2011 drought at $100 million in the Arkansas Valley. That was followed in 2012 by a roundtable project that estimated the value of agriculture in the valley at $1.5 billion.

A 2013 workshop hosted by the roundtable that brought national speakers to discuss how ag water is valued.

The roundtable selected Sandy White, who touted his upbringing on a Wyoming Ranch and his desire to preserve agriculture, for vice president over Brett Gracely, water resources manager for Colorado Springs Utilities. The vote was not close, 26-5.
