Streamflow Situation provisional data supplied by USGS
East Ohio streamflows run normal shifting to predominantly below normal for west and central Ohio, Friday. Blanchard River is no longer rated extreme low near Findlay.

Drought Map USGS 7-day average streamflow against seasonal average
Extreme hydrologic drought rating holds on to Blanchard River watershed Friday, Ohio River minor tributaries Raccoon-Symmes watershed area remains at severe drought. Moderate hydrologic drought ratings are applied on Auglaize River, Tiffin and Upper Wabash River watersheds in the Lake Erie west drainage basin. East Ohio watersheds not rated Thursday include Upper Ohio River minor tributaries Shenango and Mahoning Rivers, Little Beaver Creek, Wheeling Creek, and now Shade River is off the drought map. In the Lake Erie basin, only the Black-Rocky watershed misses the drought map. Muskingum River basin is clearing, Tuscarawas River watershed is no longer rated, Little Muskingum River remains unrated. Scioto and Great Miami basins are still rated below normal.

Flood Tracker provisional data from USGS streamflow monitors
Thirty-seven streamflow gauges record flooding in the USA Friday, up from twenty-five yesterday. WT tracks the nation's most common natural disaster in New York, Ohio, Georgia and Louisiana. As of this report, twelve monitors in the four states above mentioned indicate active flooding.

Ohio streamflows map resembles that of New York today, below normal in the west, normal in the east. As of this report there is no active flooding or high flows.

Georgia, Day 23: Gulf of Mexico basin has an active flood going on today for the first time since Flint River flooding ended at Bainbridge on March 18. This is the first we have heard from Ochlockonee River, flooding just after 9 am this morning as observed and recorded across the GA line near Concord, Florida. On the Atlantic side of the drainage divide, Alabaha River is back on the flood radar at GA 203 near Blackshear, overtaking flood stage for the second time in a week. Alabaha was late to join in the March flooding frenzy, waiting until March 23 to make a three day excursion out of the channel. That flood stopped on Tuesday this week, and back again yesterday, running and inch over flood stage at this report. Little Satilla and Satilla Rivers are actively flooding near Offerman and Atkinson, respectively. Savannah River is still more than three feet over flood stage near Cylo; Altamaha River running almost a foot over near Baxley, Altamaha tributary Ohoopee River is as high as yesterday, if not not higher, ten to eleven inches over flood stage near Reidsville.

For New York, east state streamflows run normal to much above normal, the highest flows occurring now in the Delaware River watershed and Long Island creeks and streams. Quite the opposite, the west interior and counties bordering Lake Erie and Lake Ontario are below normal to much below normal, with moderate hydrologic drought on Alleghany River watershed in the southwest and a larger area of west interior Finger Lakes region rated below normal on the drought map Friday.

In Louisiana, Pearl River, the east state border continues to overflow near Bogalusa in Washington Parish and at the Town of Pearl River in St. Tammany Parish. In northwest LA, Bayou Dorcheat is still flooding near Springhill and Bayou Bodcau is still six and a half feet above flood stage near Shreveport. On the west LA border, the Sabine River runs three inches over flood stage near the Ruliff, TX monitoring station maintained by the Texas-Oklahoma Water Science Center.

See black tags on the map for active flood, blue for high flow, 99th percentile or more.
