The Cuyahoga Valley National Recreation Area encompasses about 24 miles of the middle reach of the Cuyahoga River and parts of four major tributaries -- Furnace Run, Brandywine Creek, Chippewa Creek, and TInkers Creek. Water quality in this reach does not meet Ohio water-quality standards for dissolved oxygen, fecal bacteria, ammonia, and lead. Point sources of effluent contribute contaminants.
On the basis of a review of scientific and technical literature, National Park Service management goals, and water-quality data collected by the U.S. Geological Survey, three subject areas for future study are suggested: (1) The dissolved oxygen regime, (2) chemical quality of base flow, and (3) quality of storm-water runoff.
