Streamflow Situation from USGS Waterwatch based on real-time flow monitors across Ohio
Seasonal normal flows dominate the current streamflow chart for Ohio Thursday with one station recording much above normal on Sandusky River and seven rated stations registering below normal flows statewide. No extreme high or low flows show as of this update.
Drinking Water matters
Ohio EPA publishes current drinking water advisories with the following notation "Public water systems are required to monitor their water regularly for contaminants. Currently, more than 95 percent of community water systems meet all health-based standards. When a system doesn't meet a standard, consumers are notified. Notifications may be in the form of signs or multimedia announcements."
WTOH.us checks in on the OEPA issued list regularly for new DW advisories and for the resolution of long term advisories. These drinking water advisories result from the standard monitioring and measurements in violation of quality parameters. Boil water advisories posted to the map as a result of water main breaks, service disruptions, loss of water pressure come up intermittently with advice provided by the drinking water facility to their impacted customers.
Drought map from USGS Waterwatch 7-day average streamflow compared with historic flow for today's date
No part of Ohio is rated below normal or any degree of drought.
Harmful Algal Bloom update based on the National Centers for Coastal Ocean Science (NCCOS) satellite monitoring program
The latest image from NCCOS was captured on Jan 16 with surface wind conditions measured at 22.2 mph. This image is completely cloud obscured. The image of Jan 15 shows some open water off Catawba Island.
In spite of high wind, widespread HAB is visible off Catawba Island occupying open water in and around South Bass, Middle Bass and Kelleys Islands at 100 thousand cells per 100 ml. The image captured Jan 14 showed extensive HABs north of the international border up to the north shore.
See the HABs button to the right of the map for more information.
The height-of-land divide in Ohio runs from Mercer County in the west angling northeast up to Ashtabula County on the east state border. Streamflows north of the divide feed Lake Erie, flows south of the divide run to the Ohio River, part of the Mississippi River basin that drains the majority of interior North America to the Gulf of Mexico.
As streamflow conditions shift and change in the Ohio River basin, track the effects south down the Mississippi River into to Louisiana. Louisiana is experiencing drought relief. As of Friday January 12, the Mississippi River channel through north Louisiana departed the drought map following the most prolonged and severe dry conditions in decades. As of this update, higher Ohio River flows help to shift the drought map of Louisiana. As of this update, moderate drought remains along one river channel in southwest LA with some below normal area hanging on through the west part of the state. East Louisiana is completely clear of the drought map today. To see how surface water streamflows in the Mississippi River basin impact downstream water levels, visit WTLA.us.
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.
