From The Sensors provisional data on river flooding from the network of USGS streamflow monitors
Seventy-three streamflow gauges indicate flooding in the USA Sunday, up from thirty-seven Friday. WT tracks the flow levels on three of these flood events, as the sensors read and record it, all occurring in the state of Louisiana.
Louisiana: Region 7 Amite River flooding ended at Hwy 22 near Maurepas on Saturday. The flooding that began on June 4 in west Louisiana has been receding at a steady rate over the last several days. Bayou Bodcau Lake is down another six inches overnight, currently recorded half a foot above flood stage near Shreveport, indicating the possible end of this flood by Monday morning. In Region 4, Sabine River is still running a shade over flood stage with the expectation this will be over today near Logansport. Downstream near Ruliff the water level is eight inches over the channel, the flow volume down to 17 thousand cubic feet per second from a peak flow in the 50 and 60 thousand range. For more info on the flooding in Louisiana, see black tags indicating flood flow volume and gauge height updated daily on the map to the right.
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.
