Linworth Run (Carhart Run?)
Articles in Ravinia, Fall 2010/Winter 2011 describe Linworth Run as the stream shown just north of Plesenton Dr. (which circles around Jeffers Mound, not shown on the map). The stream south of Plesenton Dr. currently carries the name of Linworth Run.
Linworth Run enters the Olentangy River at RM 9.90 in Franklin County. The Ohio EPA monitored this tributary in 1999 at RM 0.90 (Linworth Rd.) Water quality in Linworth Run appears threatened (Ohio EPA 1999). As classified by the Palmer Drought Severity Index, severe to extreme drought conditions were indicated for the period between July and October 1999 (Ohio DNR 1999).
NOTE: After this was written, some further research uncovered an article written for Ravinia (Friends of the Ravines' newsletter) in 2010 . It seems that the historical Linworth Run is actually bit north of this stream, and it was perhaps an EPA error that attached the Linworth name to the stream. FLOW is attempting to find the actual name of this stream. Older maps designate the manmade, ditched portion of the stream as Carhart Ditch or Run, but evidence hasn't been found that would prove that the stream itself is named Carhart Run. Stay tuned!
