Dugway Brook Watershed
The Dugway Brook Watershed is a nine-square mile basin in Cleveland, Ohio and its east side suburbs, which drains storm runoff into Dugway Brook and feeds into Lake Erie. Dugway Brook is one of the five "bluestone brooks" of Cuyahoga County, also including Dean Brook, Euclid Creek, Nine-Mile Creek, and Doan Brook,〔Larick, Dr. Roy, "The Bluestone Brooks: Heart of the Eastern Inner Ring Landscape - A Natural and Historical Exploration," (), retrieved on August 16, 2008.〕 and their watersheds which feed Lake Erie.
==History==
Along with the other bluestone brooks, the east and west branches of Dugway Brook were formed about 14,000 years ago〔Larick, Dr. Roy, "The Bluestone Brooks: Heart of the Eastern Inner Ring Landscape - A Natural and Historical Exploration," (), retrieved on August 16, 2008.〕 during the last glacial period, near the end of the Wisconsin glaciation. Both branches rose on or near the campus of John Carroll University in southeastern University Heights, descending and meandering roughly parallel in a northwesterly direction, then passing through Cleveland Heights, East Cleveland, and the City of Cleveland, where the two branches merge at a point just south of what is now Interstate 90. Dugway Brook then cuts northerly through the shoreline suburb of Bratenahl as a single watercourse, and finally discharges into Lake Erie.〔Beach, David, "Dugway Brook," () (June 13, 2007), retrieved on August 16, 2008.〕
Dugway Brook is now an almost entirely enclosed culverted watercourse,〔Beach, David, "Dugway Brook," () (June 13, 2007), retrieved on August 16, 2008.〕 running in its natural channel under and alongside streets and city parks built around it. The brook appears to have been culverted early in the 20th century, partly because of the nuisance of septic contamination to nearby residents. This contamination became a concern of the Ohio State Board of Health, which in 1914 ordered the City of Cleveland to improve the sewer system involved by 1916, before the upstream suburbs experienced dense development.〔State of Ohio, "Executive Documents: Annual Reports for 1914 Made to the Eighty-First General Assembly, Regular Session of the State of Ohio, Part III," (), retrieved on August 16, 2008.〕
Culverting also maximized the development potential of surrounding land. About 94% of the watershed is now developed, with mostly mid-density housing. Approximately 45% of the watershed is in Cleveland Heights with 13% in University Heights, while less than 5% involves Bratenahl, Shaker Heights and South Euclid combined. A portion of Dugway Brook's content is overflow from sanitary sewer lines and illicit discharge. The City of Cleveland Heights has taken steps to keep the watershed's infrastructure clean and to reduce illicit discharge.
