Great Miami River Basin With the Flow Report for the Week of June 5 to June 11, 2023

Stream flows, algae blooms, drinking water advisories and spills by watershed in the Great Miami Basin

Find your location in the 3838 square mile area of the Great Miami River drainage basin. Events impacting surface water here may affect drinking water supplies for residents within the same watershed. Contaminants that are mobile in water can travel through this drainage basin to the Ohio River, which is a source of drinking water for Cincinnati and population centers in Indiana and Kentucky. Further Downstream effects from flood or low flow can eventually reach the Mississippi River, and large spill incidents or run-off from industry and agriculture can impact the drinking water supplies of communities through the Midwest and all the way to Louisiana and the Gulf of Mexico. Follow these events and incidents by watershed area.

    • Report Key With the Flow Ohio tracks trends in your watershed, posting updates from USGS WaterWatch Current Streamflow and Ohio EPA Division of Drinking and Ground Waters, Ohio Beachguard (seasonally). Flows: With The Flow describes Ohio’s rivers and tributaries from headwaters to outlet. Locate your “home body” (the river or stream nearest you) to see where the flow originates, how high it has to be for minor flooding to occur. Log in to USGS Waterwatch current streamflow for real time measurements at the monitoring station nearest you and sign up there for high flow alerts. Flow volume can change rapidly during snowmelt and rain events. Streamflow data is subject to review as sensors at the monitoring stations do malfunction from time to time. Refer to USGS Provisional Date Statement for more information. Public Drinking Water Advisories The Safe Drinking Water Act (SDWA) is federal law that safeguards the public drinking water supply. SDWA requires drinking water facilities (DWF) in every state follow national quality standards, monitor, record and report on water quality with quarterly inspections. EPA provides public access to the inspection reports, violations and enforcement actions on all registered DWFs in the USA. Annual water quality reports are required from every DWF, available from the facility, describing the treatment process and source water. DWFs are categorized as follows: - community system serves the same people year round - Non-transient, Non-Community – supplies water to at least 25 of the same people at least six months of the year - Transient, Non-Community – supplies water to intermittent users, temporarily at the location eg. Gas stations, campgrounds Note from Ohio EPA: “Boil advisories that are on record with Ohio EPA often are related to exceedances of E.coli maximum contaminant levels (MCL) at public water systems, or other major events. Staff in Ohio EPA’s district offices update (public drinking water) advisories at least monthly. Many of the advisories are based on sampling results that occur monthly, quarterly, semi-annually, or less frequently, depending on the requirements of state and federal drinking water regulations. All advisories, including those involving more immediate health risks such as boil advisories, are required to be communicated directly to consumers by the individual public water systems. When a boil advisory is not required by rule, a public water system will issue a precautionary boil advisory and the public water system would not be required to submit it to Ohio EPA. Ohio EPA does not have a record of all (or even most) boil advisories for Ohio public water systems.” (Dina Pierce, spokesperson for Ohio EPA) Hazardous Spills Spills, fish kills, rainbow sheen and releases of contaminants in the state of Ohio are reported here by watershed, as per the data source, the Ohio Environmental Protection Agency, Office of Environmental Response. Users of this data should be aware that inconsistencies and inaccuracies may exist if these data are compared to data from other time periods due to changes in methods of data collection and mapping. This report includes spills reported to the Ohio EPA as follows: - 40 gallons or more of petroleum product - toxic chemical materials, corrosives spills of any amount - all reports impacting water bodies Spills marked with asterisk are followed up with Ohio EPA authorities for additional information on the clean-up and recovery, including notices of violation and charges under State environmental statutes, federal charges under the Clean Water Act. See Ohio CrimeBox for more information on criminal prosecutions under the CWA.
