Heavy rainfall occurred across Louisiana, Texas, Arkansas, and Mississippi in March, 2016 as a result of a slow-moving southward dip in the jet stream funneling tropical moisture into parts of the Gulf Coastal States and the Mississippi River Valley. The storm caused major flooding in the northwestern and southeastern portions 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, LA over the duration of the event. Streamflow gaging stations operated by the U.S. Geological Survey recorded peak streamflows of record at 12 locations, and 30 locations experienced peak streamflows ranking in the top 5 for the duration of the period of record. In March, 2016, U.S. Geological Survey personnel made 489 discharge measurements at 375 locations on streams in Louisiana, Texas, Arkansas, and Mississippi. Many of those discharge measurements were made for the purpose of verifying the accuracy of stage-discharge relations at gaging stations operated by the U.S. Geological resulting from flooding. Following the storm event, USGS personnel recovered and 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 areas of Louisiana and Texas for the flooding that occurred in March 2016.
