Flood Tracker provisional data from USGS streamflow monitors
Twenty-five streamflow gauges record flooding in the USA Thursday ahead of the noon hour, up from twenty three this morning with some variance in the specific sites. WT tracks the nation's most common natural disaster as a dynamic event in four states, New York, Ohio, Georgia and Louisiana. As of this report, ten monitors in these states indicate active flooding.
Pearl River has breached flood stage again near Bogalusa after a brief break over the last twenty-four hours. Pearl crept back into the channel around 2 am yesterday and stayed out of trouble until 7:30 this morning, currently out and flooding once again. Downstream at the Town of Pearl River, flooding is measured 11 inches over. In northwest LA, Bayou Dorcheat is slightly less than a foot over near Springhill. Bayou Bodcau is up six and a half feet above flood stage near Shreveport. On the west LA border, Sabine River is running four inches over near Ruliff, TX.
Georgia: A new flood signal picked up around 230 am this morning on the Satilla River at Atkinson, making five active floodings on the network of streamflow monitors in Georgia, up from four yesterday. The Satilla River flooding kicked up briefly at GA158 near Waycross, subsiding around midnight of March 27. A little more than a day later, Satilla runs over at Atkinson. Flooding in the south is the tail end of the event beginning with heavy rains March 6. Today is Day 22 of continuous flooding in Georgia, with Savannah River running three and a half feet over flood stage near Cylo, Altamaha River running nine to ten inches over near Baxley, Altamaha tributary Ohoopee River is running higher today, nine inches over flood stage near Reidsville. Little Satilla River is also higher overnight, running almost a foot over flood stage near Offerman.
For New York, Long Island posts the highest streamflows, four high flow levels in the 96 to 98 percentile range Thursday, with three creeks flowing much above normal. No active flooding reported in NYS. Update on a flood signal reported here two weeks ago: provisional data indicating flooding in Reynolds Channel at the east end of Long Beach Barrier Island turned out to be erroneous. USGS New York Water Science Center Hydrology Chief Chris Gazoorian confirmed provisional data coming from the Reynolds Channel station was incorrect, the sensors were malfunctioning. An email yesterday confirms this station is repaired and back online.
Ohio streamflows are back to normal in the east, below normal in the west. As of this report, no active flooding or high flows.
See black tags on the map for active flood, blue for high flow, 99th percentile or more.
