State of Water Infrastructure reports warned, Atlanta and Calgary experienced

Drinking Water Advisories
From the US Army Corps of Engineers and US Bureau of Reclamation report on the status of the national drinking water infrastructure released earlier this year, and Utah State University Water Research Lab report released in December, the the serious issue of the condition of North America's water infrastructure blasted into mainstream focus this past week. Atlanta, with a metro population of more than 6 million, and Calgary, Alberta in western Canada with a population 1.6 million have been under States of Emergency this week due to the failure of potable water lines. In Atlanta, the BWA has been rescinded, potable water service restored to more than one hundred thousand customers including a hospital. Similar events in Calgary this week resulted in an Emergency Order. Service has been restored, however the City of Calgary is asking residents to conserve water as the consumption rate exceeds what the City can supply. See a breakdown of the USU report here.
Current Streamflows
Ohio streamflows run normal to much above normal in all but three reference sites in the state. The highest flow levels are found in the west on both sides of the height of land divide. Much above normal flows are recorded on the Sandusky River and the Maumee River watershed. Much above normal flows dominate the Scioto River basin. Great Miami basin runs normal to above normal with one station above 90th percentile. For the remaining area of Ohio, streamflows are normal to above normal levels. Rated flow in the Raccoon Creek system is normal today, however the seven day average flow has categorized Raccoon-Symmes watershed to moderate drought overnight. The adjacent Shade River watershed is still below normal, Guernsey County Wills Creek watershed and Grand River watershed are patches of Ohio ground rated below normal on the drought map Saturday.
As of this report, there are no flood events recorded, no extreme high or extreme low flows.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Fifty-four floodings appear on the USGS network Saturday, the same as Friday. WT USA is tracking twelve of these reference flood events through our coverage area in New York, Ohio, Georgia and Louisiana. At the writing of this report, all active flood sites are located in Louisiana.
Watershed Region 4 Calcasieu River is back to flood stage near Oberlin as of 545 am this morning, this is reference flood event 12 on the Louisiana flood map. Region 2 Little River breached flood stage near Rochelle around 230 am yesterday, becoming the eleventh reference incident. Region 1 watershed Bayou Bodcau Lake is up a foot higher Saturday morning, now three and a half feet above the basin near Shreveport, on a steady rise. Caddo Lake continues flooding, monitored in two locations near Mooringsport. As of writing, the water level appears to have peaked, running not quite a foot over the basin at the dam. Bayou Dorcheat continues to flood, the level is just shy of two and a half feet over flood stage near Springhill and a shade more than two and a half feet over flood stage downstream near Minden. South into Region 4 watershed, border river Sabine appears to have peaked in moderate flood stage, four feet four inches over the channel near Logansport. Still in moderate flood stage near Burkeville, more than five and a half feet over the channel. Downstream near Bon Wier, Sabine is in moderate flood stage nearing five feet above the channel. At the last monitor, water level is a foot and three inches over, up three inches in the last 24 hours with the bulk of flood water still coming down. The east side of this same watershed is drained by the Calcasieu River, flooding more than two feet over near Glenmora and as of this update, back to flooding near Oberlin. Two flood reference locations in Regions 1 and 2 along the Texas border run above the 99th percentile, flood stage is not documented. For more information on the flood trend in Louisiana, see black tags indicating flood flow volume and gauge height, blue tags for 99th percentile flows, updated daily here.
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.
