Daily Streamflow Conditions

Click map to view current
streamflow conditions.

Real-time streamflow data for Ohio

Explanation
[color code for] High
[color code for] > 90th percentile
[color code for] 75th - 89th percentile
[color code for] 25th - 74th percentile
[color code for] 10th - 24th percentile
[color code for] < 10th percentile
[color code for] Low
[color code for] Not ranked

The colored dots on this map depict streamflow conditions as a percentile, which is computed from the period of record for the current day of the year. Only stations with at least 30 years of record are used.  The gray circles indicate other stations that were not ranked in percentiles either because they have fewer than 30 years of record or because they report parameters other than streamflow. Some stations, for example, measure stage only.

National Water-Quality Assessment Program: Lake Erie-Lake St. Clair Basins
The Lake Erie-Lake St. Clair Basins in Indiana, Michigan, New York, Ohio and Pennsylvania is one of more than 50 study units that are part of the U.S. Geological Survey's National Water-Quality Assessment (NAWQA) Program. The long-term goals of this program are to describe the status and trends in the quality of a large, representative part of the Nation's surface- and ground-water resources, and to provide a sound, scientific understanding of the primary factors affecting the quality of these resources.
