Cross Lake Flood Map Files

Heavy rainfall occurred across Louisiana during March 8-19, 2016, as a result of a massive, slow-moving southward dip in the jet stream, which moved eastward across Mexico, then neared the Gulf Coast, funneling deep tropical moisture into parts of the Gulf States and the Mississippi River Valley. The storm caused major flooding in north-central Louisiana.Digital flood-inundation maps for Cross Lake near the community of Shreveport in Caddo Parish, LA was created by the U.S. Geological Survey (USGS) in cooperation with Federal Emergency Management Agency (FEMA) to support response and recovery operations following a March 8-19, 2016 flood event. The inundation maps depict estimates of the areal extent and depth of flooding corresponding to 7 High Water marks (HWM) identified and surveyed by the USGS following the flood event.2016年3月8日至19日，受急流中形成的大规模缓慢南移槽影响，路易斯安那州全域遭遇强降雨。该急流槽先向东横穿墨西哥，随后逼近墨西哥湾沿岸，将深厚的热带水汽输送至墨西哥湾沿岸各州及密西西比河流域部分区域。此次风暴引发路易斯安那州中北部严重洪涝灾害。 美国地质调查局（U.S. Geological Survey, USGS）与联邦紧急事务管理局（Federal Emergency Management Agency, FEMA）合作，为支撑2016年3月8日至19日洪涝事件后的应急响应与灾后恢复工作，针对路易斯安那州卡多教区什里夫波特社区附近的克罗斯湖，制作了数字化洪水淹没地图。该淹没地图基于灾后美国地质调查局识别并勘测得到的7处高水位标记（High Water Mark, HWM），呈现了对应洪水的覆盖范围与水深估算结果。
