Water news for Saturday, April 20, 2024 820 am CDT
Flood Tracker provisional data from USGS streamflow monitors
Fifty streamflow gauges record flooding in the USA Saturday, down from fifty-six yesterday. WT tracks the nation's most common natural disaster dynamics through the states of New York, Ohio, Georgia and Louisiana. As of this report we are watching 14 monitors indicating active flooding: 4 in Georgia and 9 in Louisiana, 1 in Ohio.
Louisiana flooding is down to nine sites left spilling over on Saturday. Region 1 Bayou Dorcheat flooding has ended at Minden, still over at the top end near Springhill. Bayou Bodcau remains ten feet out of the basin near Shreveport. To the east in watershed Region 2, Little River is down another foot overnight, running less than an inch over flood stage as of this report, looking to end flooding Saturday morning. In Region 4, Sabine River flow is down overnight, no longer flooding at the top end near Logansport, down a foot overnight with less than a foot over downstream near Burkeville. The water level is close to four feet over flood stage downstream near Bon Wier, two feet over near Ruliff as the bulk flood water moves down to the Gulf. Calcasieu River is still four inches over flood stage near Glenmora, all downstream stations are quiet now, flooding that peaked near the major flood stage coming down and ending near Oberlin yesterday late afternoon. In Region 7, the east state border Pearl River continues to flood more than two feet over near Bogalusa, a foot and a half over flood stage downstream at Town of Pearl River.
Ohio is under a freeze watch starting late tonight into Sunday. Flooding is recorded Saturday on the Tuscarawas River below Dover Dam near Dover. Olentangy River is still running high near Delaware, Mahoning River is still high at Pricetown and Shenango River is high near the Pymatuning Dam.
Georgia begins Day 45 of continuous flooding, dropping half the number of observed floodings from yesterday. Gulf of Mexico basin and Suwannee tributary Wihlachoochee River stopped flooding at US 84 near QUitman yesterday, still overflowing near Pinetta, FL. Alapaha River is still flooding at Stateville and almost two feet over flood stage near Jennings, FL. In the Atlantic basin, Satilla River is down half a foot overnight, the last station recording flood flows heading to the Atlantic Ocean. The monitor at Atkinson records a water level just less than three feet above minor flood stage. Little Satilla stopped flooding yesterday.
As of this report, New York has no active flooding, two monitors indicate flow above the 99th percentile state wide: Swan River is still recording high flow at East Patchogue on Long Island.
See black tags on the map for active flood, blue for high flow, 99th percentile or more.
As many drinking water facilities are supplied from surface water reservoirs, the streamflow situation is pertinent to both drinking water supply and quality. High flows can stir up sediment and cause turbidity in the reservoirs, requiring additional treatments to render the water potable. Low flow volume is linked to warmer temperatures in the reservoir and can be an issue for water quality where HABs are present. WT tracks streamflow trends with an eye to the impacts on drinking water supply and quality in each of the state's watersheds. Check the watershed layer on the map to see the direction of flow and streamflows that may be impacting drinking water today.
USGS Provisional Data Statement
Data are provisional and subject to revision until they have been thoroughly reviewed and received final approval. Current condition data relayed by satellite or other telemetry are automatically screened to not display improbable values until they can be verified.
Provisional data may be inaccurate due to instrument malfunctions or physical changes at the measurement site. Subsequent review based on field inspections and measurements may result in significant revisions to the data.
Data users are cautioned to consider carefully the provisional nature of the information before using it for decisions that concern personal or public safety or the conduct of business that involves substantial monetary or operational consequences. Information concerning the accuracy and appropriate uses of these data or concerning other hydrologic data may be obtained from the USGS.
