About Maumee River at Waterville
This gauge measures Maumee River at Waterville, Ohio — the reading paddlers, anglers and outfitters on this stretch check before committing to a shuttle.
Spring walleye run; wadeability is purely flow-dependent.
Raw CFS means little on its own, so every reading on this page is shown against the USGS median for the same calendar day — 800 CFS for late July, from 93 years of record.
Because the National Weather Service also operates a forecast point here, the page carries the official flood-category ladder and the NWS's own stage-by-stage impact statements.
Maumee River at Waterville — common questions
What is the current flow on Maumee River at Waterville?
As of the last reading on this page, Maumee River at Waterville was running 342 CFS at a gage height of 1.80 ft, or 43% of the USGS median for this date. The number updates automatically from USGS gauge 04193500, which reports every 15 to 60 minutes.
Is that high or low for this time of year?
The USGS median flow for late July at this gauge is 800 CFS, calculated from 93 years of record (1930–2026). Comparing today's reading against that median is the only way a raw CFS number tells you anything — 200 CFS is a drought on one river and a flood on another.
How often does this reading update?
USGS transmits from this gauge every 15 to 60 minutes. This page bakes in the most recent reading when it is rebuilt, then refreshes live from USGS when you open it. Readings are provisional and subject to revision by USGS.
Is Maumee River at Waterville wadeable right now?
That depends on the reach and on your own judgement — riverlvl will not tell you the water is safe to stand in. What it will tell you is whether today's flow is unusually high or low for the date, against a seasonal median of 800 CFS, which is the single most useful input to that decision.
What makes the flow change on this stretch?
Rain in the basin upstream, plus seasonal baseflow. The 12-month chart shows the past year of daily values, which is the clearest picture of how this gauge behaves through the seasons.
Where does this data come from?
Flow and gage height are public-domain USGS data from gauge 04193500. Flood categories, impact statements and the forecast come from the NOAA / National Weather Service National Water Prediction Service, gauge WTVO1. riverlvl adds the seasonal comparison and plain-English summary; it is not an official source and does not issue warnings.
