With the Flow Ohio tracks trends in your watershed, posting monthly updates from USGS WaterWatch Current Streamflow and Ohio EPA Division of Drinking and Ground Waters.

Flows:

WTOH logs a snapshot of the volume of water flowing through the state’s rivers and tributaries, as per USGS Waterwatch current streamflow monitoring stations. The report captures your watershed flows from headwaters to outlet as of the date indicated.

Rivers, creeks flowing much above normal or high (in the top 10% of flow volume recorded for that system) are shown in boldface;
flows that have breached action stage appear in red,

flows in flood stage appear in boldface red type.
Ice-affected flows are shown in italics.

Flow volume can change rapidly during snowmelt and rain events. All readings are posted as they appear as of our monthly update. Check your local upstream station flow levels at the USGS WaterWatch Current Streamflow site and sign up for high flow alerts. Streamflow data is subject to review as sensors at the monitoring stations do malfunction from time to time.

Groundwater Monitor

With source data from USGS Groundwater Watch test wells, the “depth to water” in feet and inches is updated monthly here; the higher depth to water measurement represents a lower groundwater level.

Ohio Department of Natural Resources has launched a new groundwater vulnerability map, with a higher number indicating an area that may absorb and transport contaminants into the groundwater more readily.

Hazardous Algae Blooms (HABs) Beach Alerts

Hazardous Algae Bloom is the common term for cyanobacteria. HABs present in different forms, from what appears as grass clippings to spilled paint, growing in lakes and ponds, increasingly common as the water temperature increases and nutrients are in excess. HABs are capable of producing toxins dangerous to humans and pets. The toxins can be present in the water when the bloom itself is no longer visible; samples tested for the presence of toxins may lead to public health advisory or beaches being posted with warnings. Avoid contact with HABs.

Bacterial Contamination Alerts - High levels of E. coli are associated with intestinal illness. Ohio Department of Natural Resources, County Health monitor E. coli contamination on public beaches, posting alerts when the levels are above the safe threshold. While the advisory is posted, the beach remains open, however the public is advised to stay out of the water.

Alerts from the BeachGuard site are reported here in the watershed area, listing the water body impacted, including bacterial contamination and algal toxin sample test results and location details. If you see a bloom, fill out the report on Ohio EPA found here: https://survey123.arcgis.com/share/ac459f1f0b344bfa93c0486b028fbba6

Spills

Spills and accidental releases of contaminants in the state of Ohio are reported here weekly 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 of:

40 gallons or more of petroleum product
toxic chemical materials, corrosives spills of any amount
all spills impacting water bodies

Spills marked with asterisk * are followed up with Ohio EPA authorities for additional information on the cleanup 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.

Impaired Water Bodies EPA 303d list

As per the Clean Water Act, federal EPA requires all states update a list of impaired water bodies, (the 303d list) every two years; providing a period for public comments before presenting the new draft list to the EPA. The final 303d list is published as approved by the federal EPA, roughly every two years.

Impaired water bodies are defined as with contaminants measured above threshold levels set by the EPA Clean Water Act, or where the desired use is impaired.

Refer to the Impaired Water Body list for Ohio on WaterToday Ohio.
