California considers stepping in to manage groundwater basin in farm country_我的网站

It is the first time the state has made such a move, and the first step in a lengthy process that could end up requiring large farms in the area to report groundwater use and pay fees.California is starting to regulate the pumping of groundwater after years of drought and overpumping left rural residents’ wells dry and led to subsidence, or the sinking of land, in some communities. Both issues have affected the largely agricultural region, which is home to 145,000 people, and stand to worsen absent revisions to the local groundwater plan, officials said.“This is an urgent issue,” said Natalie Stork, an official at the State Water Resources Control Board. “There are urgent impacts from continued overdraft in these basins.”The state enacted a 2014 law tasking communities with forming groundwater agencies and making plans to manage the resource sustainably, starting with the most critically overdrafted basins, including the Tulare Lake Subbasin.Five groundwater agencies joined together come up with a plan for the subbasin where farmers grow cotton, almonds and pistachios. But the plan was one of six that California's Department of Water Resources deemed inadequate this year.Now, the State Water Resources Control Board will hold a hearing April 16 to decide whether to place the Tulare Lake Subbasin on probation. If it does, large pumpers would report their groundwater usage and pay fees while the local agencies draft a new plan for the basin. If they don't, the board could eventually implement its own plan.Many communities rely mainly or solely on groundwater for drinking water and farmers count on it for irrigation, especially in a drought. California muddled through a spell of dry years until a series of winter storms drenched the state and dumped massive amounts of snow in the mountains. When the snow melted, it flowed down to form the reemerging Tulare Lake, which covered vast stretches of farmland with water. California has long tended toward wet and dry periods, but scientists at University of California, San Diego’s Scripps Institution of Oceanography have said they expect climate change will lead to drier dry years and wetter wet years.。         　　中央气象台预计，今年第19号台风“紫檀”(热带风暴级)将先在北部湾海面回旋少动，23日傍晚起，将以每小时5至10公里的速度向东北转偏北方向移动，强度逐渐加强，最强可达强热带风暴级，并逐渐向广西沿海至广东雷州半岛西侧一带沿海靠近。         　　另外，今年第20号台风“简拉维”(热带风暴级)的中心23日5时位于台湾省台北市东北方向大约115公里的东海南部海面上，预计“简拉维”将以每小时5至10公里的速度向西偏南方向移动，强度逐渐减弱，将于24日在台湾海峡减弱消散。

三 |                         　　23日至25日，预计受台风“紫檀”及“简拉维”影响，海南岛西部、广西南部、广东中东部和南部、福建、台湾岛、浙江东部和南部等地部分地区有大到暴雨，局地大暴雨到特大暴雨。此外，四川盆地西南部、湖南、江西、云南等地多分散性强降水。         　　23日至24日，西北地区东部、内蒙古中东部、华北、东北地区等地多阵雨或雷阵雨，局地有暴雨或大暴雨，并伴有短时强降水、雷暴大风或冰雹等强对流天气。

四 | 25日至28日，北方地区自西向东还将出现一次降水过程，部分地区有大雨到暴雨。(完) 【编辑:王琴】。
