With one month left in what are California’s three wettest months of the year, the snowpack in the Sierra Nevada is at 27 percent of average for the start of February, said the state Department of Water Resources.
President Trump set out to erase the Obama-era Waters of the United States rule in his first weeks in office. Now the EPA has finalized an action that should keep the so-called WOTUS rule from ever taking effect.
Snowpack in parts of the Rocky Mountains is at record lows because of warmer than usual weather, “raising concerns about water supplies and economic damage,” says Inside Climate News.
State officials in Michigan drafted a plan that relies on voluntary action by farmers to reduce phosphorus runoff from fields that eventually flows into Lake Erie, where nutrient pollution feeds algal blooms in the western end of the lake, reports MLive Media Group.
Three new studies show that the West is running low on water, and that much of that decline is a result of climate change, says High Country News.
With hundreds of millions of dollars at stake in carrying out Iowa's Nutrient Reduction Strategy, which calls for a 45 percent cut in nitrogen and phosphorus levels in waterways, "a new and controversial debate is looming," says the Des Moines Register. Environmentalists and scientists want to rely on water-quality monitoring to determine progress while farm groups say the best way is to tally conservation practices put in place on the land.
More than half the flow of rivers in the upper Colorado Basin is derived from groundwater, according to a study by the U.S. Geological Society. The study's authors hope it will compel state water managers to ask important questions, since rivers are a key source of irrigation and drinking water across the west. For instance, should a farmer’s use of a nearby river be limited if he or she is also pumping large amounts of groundwater?
