Morgana Run drains the central portion of the city of Cleveland east of the Cuyahoga River. It has a total drainage area of 2,280 acres and a total length of 4.8 miles. Morgana Run’s culvert originates at E. 97th between Sandusky Ave. and Way Ave.

It runs predominantly east-to-west to E. 49th, where, in dry weather, its entire flow drops into the Southerly Interceptor and is tributary to the Northeast Ohio Regional Sewer District’s Southerly waste-water treatment center.

The remaining section of Morgana Run enters the Cuyahoga River on the Mittal Steel property south of the former location of the Clark Ave. bridge at River Mile 4.9.

Around 1910, Morgana Run was culverted and in some places relocated to follow Morgana Ave. In 1960 and 1961, the Morgana Run culvert from I-77 to Independence road was reinforced allowing the Republic Steel Corporation to use the land above Morgana Run as a bulk storage facility for coal, coke, and ore.

In 1969, all of the dry weather flow in Morgana Run upstream of E. 49th was diverted by a weir through a 42-inch pipe into the Southerly Interceptor. The weir is overflowed only in wet weather, when many combined sewer overflows are tributary to Morgana Run upstream.

Until December 1991, when the LTV Steel Company’s coke plant was removed from service, its treated effluent and cooling waters were discharged at Morgana Run between the river and Independence road at a rate of approximately 10,000 gallons per minute.
