Water in the Intermountain West

What does the West’s water supply look like today? Use these graphs to investigate current data on precipitation, snowpack, drought intensity, and reservoir storage. These graphs are taken from the Intermountain West Climate Dashboard by the Western Water Assessment and are updated daily for decision making support for water managers and users. Find ideas for using these graphs in the classroom and tips for water conservation in your school.

Ideas for the Classroom

Climate or Weather: What's the Difference?

Ask students to explain which graphs represent weather, which graphs represent climate, or if some graphs represent both weather and climate.

You Make the Call: Decision Making
Use the following scenarios for a role-playing exercise with student:
You are the water manager for a suburb of Denver that draws from streams and reservoirs in both the South Platte and Colorado River watersheds (map of the Denver Water collection system). Nearly all of your annual water supply comes from snowmelt in the spring. If you expect a below-normal water supply (less than 80% of normal) this year, you will need to arrange ahead of time to buy water from local farmers to supplement your supply. This is very expensive, but if you don't do it, your city might run out of water. Which information on the mini-dashboard would you look at to decide whether to buy water this spring? Given that information, would you buy water? Why or why not? What additional information would you want before you make a decision?  Are there other choices beyond purchasing water that could make up the water shortfall for your city?

Now you are the water manager for Durango in southwestern Colorado, and your water comes from the Animas River that flows through Durango (part of the Dolores watershed). You have the same situation as the manager above. Would you buy water this spring? Why or why not?

How Does Your Water Footprint Measure Up?
Have students calculate their household water usage using Graces Water Footprint Calculator (gallons/day), then convert to gallons/year, and then convert to acre-feet/year(1 acre-foot = 325,851 gallons). Next, have them find how many acre-feet of water are stored in the closest reservoir in the Upper Colorado Reservoir Storage graph (current acre-feet stored is the first number in the line beneath the reservoir name). How many years would the reservoir last if just the student's household were using it? If the whole city had the same water usage as the student? The whole state? Compare results among students.

Water Now and Water Then
Ask students to find historic precipitation averages in their hometown for the current climate period (1981-2010) and a past climate period (30 year period). Find historic annual precipitation records through the United States Historical Climatology Network. Select your hometown (or the closest town to it), "Get Monthly Data," and select "Annual Precipitation (PRECIP)" under #4. Have students compare the climate periods and discuss changes in precipitation, and hypothesize causes and implications of changes (if there are any).

Glossary

Average: In the figures above, "average" describes the statistical mean of data from years 1981-2010.

Drought: The US Drought Monitor map uses drought indicators including (but not limited to) the Palmer Drought Severity Index, soil moisture, streamflow, precipitation, measures of vegetation stress, and reports of drought impacts.

Intermountain West: The geographic and geological region located between the Rocky Mountains on the east and the Cascade Range and Sierra Nevada on the west in known as the Intermountain West

Percentile (as used in the USGS Streamflow Map): A value on a scale of one hundred that indicates the percent of a distribution that is equal to or below it. For example, on the map of daily streamflow conditions, a river discharge at the 90th percentile is equal to or greater than 90 percent of the discharge values recorded on this day of the year during all years that measurements have been made. [from USGS]

Water Year: From October 1 of the preceding year to September 31 of the following year. Hydrologists use this time period to capture the snowpack and snowmelt of one year, beginning with snowpack accumulation in the preceding October. For example, water year 2014 begins October 1, 2013 and ends September 31, 2014.

Niwot Ridge Live TundraCam

Visit the filming location of "Water: A Zero Sum Game" without leaving your classroom.  Take control of the Niwot Ridge LTER Program HD TundraCam for a real-time, panoramic view of the Front Range from 11,600 feet.  Students can use the camera as part of a virtual field trip to the Niwot Ridge Long-term Ecological Research site.

Mountain Snowpack Data Analysis

In Colorado, the majority of the water supply comes from snowmelt. Researchers at the Niowt Ridge LTER site monitor snowpack properties using snow depth sensors. In this activity, educators and students use real data to play the role of water managers. What is the snow water equivalence, or the amount of water contained in the snow in the Green Lakes Valley Basin? What does that mean for the basin's water storage? Given that the average person uses 82 gallons of water per day, calculate the number of people that the basin could supply?

In Time Of Drought

Alfalfa grown with Colorado River water is a case study of how and why water gets used as it does.

Why Farmers Care About Snowpack

Like much of the far West, northern Nevada is in the grips of a historic drought. The federal government has declared much of the region a disaster area. Snowpack in the Sierra Nevada is at historically low levels. That means feed will be in short supply, which is a big deal, because the alfalfa that's grown here doesn't just stay local. NPR talked with Pete Olsen about drought on his fifth-generation dairy farm in Fallon, Nevada.
