Much below normal streamflows central Ohio
June 3, 2024 1102 am EDT
Current Streamflows from the network of USGS river monitors in Ohio
Seasonal normal is the most common rating for the creeks and rivers of Ohio Monday. An area of below normal activity starts on the Mississippi basin side of the state divide in the tributaries of the Scioto River basin and extend across into the Muskingum River basin. Ten stations are rated below normal in this area, three of these are much below the seasonal normal, ranging from 3rd percentile to 7th percentile. The odd below normal flow pops up in the lower Great Miami Basin and minor tributaries of the Ohio River. At the time of this report, there are no active floodings recorded in Ohio, no extreme high or extreme low flows.
HABs Tracker

Sixteen Recreational Public Health Advisories are on the list Monday, as reported here yesterday. Ten Lake Erie beaches have high levels of bacterial contamination, all in Erie County. Three algal toxin advisories continue for Grand Lake, Shawnee Turkey Creek Lodge and Roosevelt Camp in Scioto County and East Fork Lake in Clermont County populate the beach advisory list. More to follow as new lab results come in throughout the day.
NCCOS uploads new satellite photos of Lake Erie west basin on a near-daily basis. The latest image was captured June 2 at a surface wind speed 14.2 mph. This image is completely cloud obscured. A previous clear image captured May 31 revealed moderate concentration HAB activity in the outer Sandusky Bay area around Johnsons Island. For details, see the report here.
WT USA Flows and Flood Tracker provisional data from the network of USGS streamflow monitors
Forty-five streamflow gauges indicate flow above flood stage in the USA Monday, up from forty-three yesterday. Two floods occur inside the WT coverage area, both in Louisiana.
The State of Louisiana reckons its surface area in watershed regions as a key organizing factor for public decision making, planning and investment. Watersheds organize the areas drained by major rivers, describing the surface area and resources in the impact zone for water-related weather, runoff of nutrients and contaminants and indicates changes in pressure on drinking water supplies and quality. Supporting the coordination of public services and administration by Parishes and municipalities to effectively manage flood, fire and other natural climatic events, WTLA.us communicates water related information using the accepted and common format in use in Louisiana. Watershed Region 4 extends from the west border with Texas to the edge of the area drained by the Calcasieu River, down to the outlet in the Gulf of Mexico. Flooding has been ongoing in Region 4 on the Sabine and Calcasieu Rivers on and off since late January. At the time of this report, Region 4 flooding continues on the Calcasieu River near Glenmora, currently signalling a gauge height five inches over the channel on a slow declining trend. West border Sabine River continues to overflow the lower channel in southwest Louisiana this morning, running the same level nine to ten inches over minor flood stage as reported here over much of the last week. NWS alerts about thunderstorms developing today and tomorrow that could overwhelm the saturated soil in the northwest Regions 1 and 2, possibly leading to flash flooding in some locations. More to follow here. See black tags indicating flow volume and gauge height, 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.
