Tiffin River river
Total streamflow across the Tiffin River was last observed at 190 cfs, and is expected to yield approximately 377 acre-ft of water today; about 22% of normal. River levels are low and may signify a drought. Average streamflow for this time of year is 847 cfs, with recent peaks last observed on 2020-05-20 when daily discharge volume was observed at 11,280 cfs.
Maximum discharge along the river is currently at the Tiffin River Near Evansport Oh reporting a streamflow rate of 119 cfs. This is also the highest stage along the Tiffin River, with a gauge stage of 10.17 ft at this location. This river is monitored from 2 different streamgauging stations along the Tiffin River, the highest being situated at an altitude of 692 ft, the Tiffin River At Stryker Oh.

Maximum streamflow discharge by year
The single highest aggregate discharge recorded each year. Spotting the multi-year trend reveals droughts vs. wet cycles long before the headline daily flow does.

Streamflow elevation profile
Each bubble is one gauge along the river, plotted by current streamflow (x-axis) vs elevation (y-axis), sized by gauge stage. Reading top-to-bottom traces the river from headwaters down to its mouth -- you can see flow accumulate as elevation drops.

Tiffin River
The Tiffin River is a tributary of the Maumee River that runs through northwestern Ohio and northeastern Indiana. The river is approximately 84 miles long and has a watershed of 1,140 square miles. The Tiffin River originates in Williams County, Ohio and flows through several small towns before joining the Maumee River. The river has been used for agricultural irrigation and recreation, including fishing and canoeing. The Tiffin River is also home to several reservoirs and dams, including the Independence Dam and Reservoir, which was built in the 1930s to provide flood control and hydroelectric power. The reservoir is a popular spot for fishing and boating. The river has a long history, dating back to Native American settlements and European colonization in the 18th century.

Set per-gauge push alerts (e.g. "alert me when flow at the Russian R Nr Healdsburg crosses 5,000 cfs"), and Snoflo's iOS app pushes the moment USGS reports the crossing.
About the Tiffin River
Where does the data for the Tiffin River come from?
Streamflow and gauge stage data are sourced from the U.S. Geological Survey (USGS) National Water Information System. The aggregate flow shown at the top of the page is computed by Snoflo as the sum of all monitored gauges along the river.
How is "percent of normal" calculated?
Today's aggregate streamflow is compared to the historical average aggregate streamflow on this calendar day across the river's full record. 100% means right on average; values above 100% indicate above-normal flow (wet year); values below indicate below-normal (dry year or drought).
Why are some gauges showing very different flows?
Gauges along a river measure flow at different points: headwater gauges read what's coming off the snowpack or mountain runoff; downstream gauges integrate everything upstream, including tributary inputs. Wide spreads usually mean a tributary is contributing significantly between gauges.
What's the elevation profile chart showing?
Each bubble is one gauge along the river, plotted by streamflow (x-axis) and elevation (y-axis), sized by gauge stage. Reading top-down traces the river from headwaters to mouth -- you can see flow build as elevation drops.
Can I get alerts when a specific gauge crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app on a per-gauge basis. Open any individual streamgauge from the table above and favorite it to set a discharge threshold.
