You are now in California and the U.S. category.

Gov. Jerry Brown declared an end to California’s drought this month, lifting emergency water restrictions in all but a few counties across the state. This winter has been the wettest on record for Northern California, but that doesn’t mean California’s problems are over. Here & Now‘s Jeremy Hobson talks with Jay Lund (@JayLund113), professor of civil and environmental engineering and the director of the Center for Watershed Sciences at the University of California Davis.

Just a week after Governor Jerry Brown declared the end of the California drought emergency, the northern half of the state logged its wettest year into the record books. But that doesn’t mean California’s water problems are over. On 13 April, rainfall measuring stations in the Sierra Nevada mountains recorded 89.7 inches of water. The previous record set in 1983 was 88.5 inches. In the past 12 months, California has simultaneously dealt with the effects of not enough water and far too much of it.

When Hurricane Katrina struck Louisiana in 2005, cities inland saw an influx of evacuees escaping the storm and its aftermath. Now, a new University of Georgia study predicts that this could happen again as a result of sea-level rise. In a paper published today in Nature Climate Change, researchers estimate that approximately 13.1 million people could be displaced by rising ocean waters, with Atlanta, Houston and Phoenix as top destinations for those forced to relocate.

Oregon and Washington lead the way in state programs that facilitate environmental water transfers. A new Stanford study concludes Colorado Basin states, including California, have lots of catching up to do. Water transfers are an important way to share a limited resource, especially to help fish and habitats that were historically left with scraps when water rights were parceled out around the West. The water for such transfers usually comes from farmers, who free up water through some kind of conservation measure. By transferring the saved water, a farmer can help imperiled fish and make some money.

Another storm system will pass through the Central Valley on Tuesday, bringing light, scattered showers. Rain will start developing around midnight on Tuesday and will continue into the afternoon. The bulk of the system will pass through between 7 a.m. and noon, said Scott Borgioli, WeatherAg chief meteorologist. Scattered showers will bring less than a quarter-inch of rain. Tuesday’s high temperatures upper 60s, but a warming trend could push the mercury above 85 this weekend.
