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.。“新谢泼德”飞行器的设计目标是将宇航员和科研载荷送入太空,其飞行高度可达约107千米,超过距地表约100千米的“卡门线”,这是国际航天界定义的地球大气层与太空的边界。蓝色起源公司表示,在此次试飞前,“新谢泼德”飞行器已连续成功完成22次飞行测试,其中包括3次逃生测试,表明飞船的逃生系统能够在飞行任何阶段安全启动。
