暴雨和大雪使图莱里湖恢复生机
Floodwater (dark blue) stands out against the vegetation in agricultural fields around Tulare Lake near Corcoran, California, in this enhanced color image taken by Landsat 8 on March 29, 2023. Heavy rain and snow in the first three months of 2023 have once again brought water to Tulare’s lakebed, but also flooding several nearby towns. 2023 has been the wettest year in the region’s history.
Tulare Lake, in California’s San Joaquin Valley, was once the largest freshwater lake west of the Mississippi River. By 1920, the rivers that fed the lake were dammed and diverted for uses such as irrigation. Since then, the lakebed has been covered with farms that grow a variety of crops.

2023年3月29日，在这张由陆地卫星8号拍摄的增强彩色图像中，洪水（深蓝色）与加州科克伦附近图拉里湖周围农田的植被形成鲜明对比。2023年前三个月的大雨和大雪再次给图莱里的湖床带来了水，但也淹没了附近的几个城镇。2023年是该地区历史上最潮湿的一年。
图莱里湖位于加州圣华金河谷，曾经是密西西比河以西最大的淡水湖。到1920年，流入该湖的河流被筑坝改道用于灌溉等用途。从那时起，湖床就被种植各种作物的农场所覆盖。
