WATER-QUALITY RECORDS
The data described in the following table were collected and analyzed as part of the NAWQA (National Water-
Quality Assessment Program) project in the Lake Erie-Lake St. Clair Basin. The objectives of the NAWQA program are
to broadly characterize the water quality of the Nation's streams and aquifers in relation to human and natural
factors. This project is one of 60 river basin and aquifer assessment projects being implemented across the nation.
At any one time, 15 to 20 of these projects are actively collecting data. The period of high-intensity data
collection for the Lake Erie-Lake St. Clair Basin project is in water years 1996-98.
There are four stream sites in Ohio for which data are being reported in this publication as part of the NAWQA
study: Auglaize River near Ft. Jennings (04186500), Maumee River at Waterville (04193500), Cuyahoga River at LTV
Steel at Cleveland (04208504), and Grand River at Harpersfield (04211820). Three sites are reported in the 1997
Michigan annual data report: Black River near Jeddo, MI (04159492), Clinton River at Sterling Heights, MI (04161820)
and River Raisin near Manchester, MI (04175600). Two Sites are reported in the 1997 Indiana annual data report:
St. Joseph River near Newville, IN (04178000), and Maumee River at New Haven, IN (04183000). One site is reported in
the 1997 New York annual data report: Cattaraugus Creek at Gowanda, NY (04213500).
These data also can be obtained electronically at http//oh.water.usgs.gov/nawqa.index.html.
---, no data; <, concentration or value reported is less than that indicated; E, estimated value; K, value is
