Streamflow Situation from USGS Waterwatch based on real-time flow monitors across Ohio
Much below normal flows persisting in the Lake Erie west basin with an extreme low flow in Sandusky River watershed Monday. now apply twice on the Auglaize River, the watershed area also rated severe drought. Blanchard River lit Thursday much below normal and as of Friday morning, we have a tributary of the Sandusky River reporting much below normal. On the east side of the Lake Erie basin, Cuyahoga River is still much below normal at the last monitoring station before the outlet, and Conneaut Creek is much below normal as we saw yesterday.
Drought situation from USGS Waterwatch 7-day average streamflow compared with historic flow for today's date
As expected, the drought map has taken on more real estate over the weekend. Auglaize River watershed continues in severe hydrologic drought mode with all adjacent watersheds rated below normal. Tiffin River watershed and Upper Maumee River watershed are back on the drought map joining Blanchard, Lower Maumee, St Marys, St Josephs watersheds all rated below normal. Mahoning River watershed remains below normal, joined by Little Beaver Creek watershed rated below normal over the weekend. Wheeling Creek watershed remains below normal, Shade River remains on the board, Monday joined once again by Raccoon-Symmes watershed all below normal.
Upper and Lower Great Miami River watersheds hang on to below normal rating. Scioto basin's Tygarts watershed is still on the drought map rated below normal as last week.
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 the drought conditions shift and change in the Ohio River basin, track the effects south down the Mississippi River into to Louisiana, rated "Exceptional Drought", the highest category on the National Drought map. Visit WTLA.us for more information on downstream effects.

Drinking Water matters
Triad Middle School in North Lewisburg was cited by OEPA November 20 with a public drinking water "Sensitive Persons Advisory" for arsenic above the maximum contaminant level (MCL). According to the OEPA records, Triad Middle School runs a non-transient, non-community water system serving 251 to 1000 persons from a groundwater source. The running average test result for 3rd quarter 2023 was 11 micrograms per liter arsenic where the MCL is 10 micrograms per liter.
Triad Middle School responded promptly to our inquiry, forwarding the notice letter sent to parents November 28. From that notice, "As soon as we were informed about the MCL violation, Triad worked with the Ohio EPA to look for options to address the issue. We will first replace the resin in our water system. This should help to filter the water and reduce the “naturally occurring element” from our systems. The second recommendation is to add additional summer procedures to regularly flush the MS/ES water system out to ensure water does not sit for long periods of time and cause the 3rd quarter reading to be
elevated."
Arsenic is a naturally occuring inorganic chemical that can cause health issues for sensitive persons if consumed in excess. The sensitive persons advisory does not indicate a need for an alternate water source, such as bottled water.

NWS Outlook
Rain in the forecast for Cleveland and Toledo, 70% chance of rain may bring some relief to the very dry conditions in the northwest.
Harmful Algal Bloom update based on the National Centers for Coastal Ocean Science (NCCOS) satellite monitoring program
A new satellite image has been released by NCCOS, taken December 14 at undetermined surface wind speed. This image shows the Ohio shore of Lake Erie clearly for the third day in a row. Small localized HABs along the Ohio shore of Lake Erie are observed filling in from Dec 12 to 13, now appear to be thinning out again. The HABs are clearly visible along the Lake Erie shore and in open water from Sandusky Bay outlet to Vermilion-on-the-Lake in this latest image. The concentration of all HABs appears consistent at 100 thousand cells per 100 ml or less. Wind speed is undetermined, and a high wind warning from NWS for Monday may continue to cause an underestimate of the HAB area in Lake Erie.
