Summary
Heavy rainfall occurred across Louisiana, Texas, Arkansas, and Mississippi in March 2016 as a result of a slow-moving southward dip in the jetstream, funneling tropical moisture into parts of the Gulf Coastal States and the Mississippi River Valley. The storm caused major flooding in the north and southeastern parts of Louisiana and in eastern Texas. Flooding also occurred in the Mississippi River Valley in Arkansas and Mississippi. Over 26 inches of rain were reported near Monroe, Louisiana over the duration of the storm event. In March 2016, U.S. Geological Survey (USGS) personnel made over 490 streamflow measurements at over 375 locations in Louisiana, Texas, Arkansas, and Mississippi. Many of those streamflow measurements were [...]
Summary
Heavy rainfall occurred across Louisiana, Texas, Arkansas, and Mississippi in March 2016 as a result of a slow-moving southward dip in the jetstream, funneling tropical moisture into parts of the Gulf Coastal States and the Mississippi River Valley. The storm caused major flooding in the north and southeastern parts of Louisiana and in eastern Texas. Flooding also occurred in the Mississippi River Valley in Arkansas and Mississippi. Over 26 inches of rain were reported near Monroe, Louisiana over the duration of the storm event. In March 2016, U.S. Geological Survey (USGS) personnel made over 490 streamflow measurements at over 375 locations in Louisiana, Texas, Arkansas, and Mississippi. Many of those streamflow measurements were made for verifying the accuracy of stage-streamflow relations at gaging stations operated by the USGS. Peak streamflows were the highest on record at 14 locations, and streamflows at 29 locations ranked in the top five for the period of record at U.S. Geological streamflow-gaging stations analyzed for this report. Following the storm event, USGS personnel documented 451 high-water marks in Louisiana and on the western side of the Sabine River in Texas. Many of these high-water marks were used to create 19 flood-inundation maps for selected areas of Louisiana and Texas that experienced flooding in March 2016.
This data release contains the actual flood-depth measurements made in 13 selected river basins of Louisiana, Texas, and Mississippi during March 2016. The file types contained in this data release are shape files, metadata, and images created by mapping software. Measurements were made in these 13 basins to document flood depth and assist in the estimation of flood-inundation area. The flood-inundation maps created from these measurements can be found in Breaker and others (2016).
