National Geographic – I flow out of a cave at 9,000 feet elevation near Navajo Lake at Cascade Falls, Utah, descend toward Lake Mead at 1,000 feet, and empty into the Colorado River. I could tell you tales of other parts of my course, but the favorite section of my journey is the 8½ miles through the steep Navajo sandstone canyon walls located in what is now called Zion Canyon.
After a dry and mild winter, May in Utah was wetter than usual. Salt Lake City International Airport had a record-setting 18 days with measurable precipitation, said hydrologist Brian McInerney. Mike Tea, a local water master, said the rains helped his irrigation company keep up with demand.
Viewed from space, as in NASA’s “Blue Marble” below, one quickly recognizes that water covers most of the earth’s surface. Even on land, the hydrologic cycle is responsible for its dominant features, from glaciers and rivers to jungles and deserts. Below the land surface, groundwater is found almost …
A mild winter brought record-setting warm temperatures and little precipitation, and Utah’s water conditions are well below average for the fourth year in a row.
“Any hydrologic indices that we have, have gone wrong,” said Brian McInerney, a hydrologist with the National Weather Service in Salt Lake City.
What does the future hold for Utah Lake, its users, and its ecosystem? The concluding article in a five-part series.
Nutrients have long been pollutants of concern in surface waters. Some argue the need to strictly control nutrients entering Utah Lake, while others question the effectiveness of such actions. How do nitrogen and phosphorous affect Utah Lake?
Green infrastructure is becoming a more viable and popular strategy for managing urban waters. Can botanical gardens serve as green infrastructure? Research at the University of Utah investigated environmental benefits and impacts of Red Butte Garden on Red Butte Creek.
Proposals to extract more value from Utah Lake have included reclaiming land for agriculture, dredging to promote water clarity, and constructing artificial islands and trans-lake bridges. Are such projects feasible?
Can Utah Lake ever be clear? What are its real water quality problems, and how can they be solved?
Attitudes towards Utah Lake range from “priceless, beautiful lake” to “worthless, swampy pond.” What is it naturally?
Given several recent inquiries about where to find water data, I have compiled this list of a few common resources which I have found particularly useful. If you would like to share others, please comment.
Some 250 people gathered in Provo on October 28 for the 21st annual Utah Water Summit under the theme “Your Water, Your Stewardship.” Read the highlights here.
At the turn of the “water year,” Randy Julander, Utah Snow Survey supervisor, comments on the state’s status.
With recent summer storms along the Wasatch Front, it is a good time to discuss what happens when it rains. Four processes govern post-precipitation hydrology.
