Federal Water Tap, May 28: Number of High Hazard Dams in the U.S. Increases

/in /by

Roughly one in every six structures in the Army Corps of Engineers dams database is rated as “high hazard,” meaning a dam failure would kill people, according to a recent update. Since 2009, the number of high hazard dams has increased by six percent, to 14,726. Three-fifths of the high hazard dams have an emergency […]

Federal Water Tap, May 20: Fracking Regulations, Arctic Strategy, Infrastructure

/in /by

The Bureau of Land Management’s revised regulations for hydraulic fracturing, aka fracking, on federal lands pleased almost no one outside of Congress. The proposal has three prongs: disclosure of chemicals in the fracking fluid, quality-control for well construction, and wastewater disposal. The BLM’s goal is to streamline the reporting process “without introducing unnecessary new procedures […]

NASA and the California Department of Water Resources are collaborating on a project to provide a near real-time assessment of mountain snowpack. The three-year pilot study of watersheds in California and Colorado began last month. The lasers and spectrometers on the Airborne Snow Observatory, carried aboard aircraft that fly below the cruising altitude of a […]

All Wet – A Stormy Spring Stymies Farmers in the U.S. Midwest

/in /by

In much of the Corn Belt, too much rain has left fields too soggy to sow. Image courtesy of Midwest Regional Climate Center Iowa had its wettest April on record, and much of the Midwest saw precipitation levels at 150 percent to 300 percent of normal. Farmers have delayed planting crops because of soggy fields. […]
