Parts the the Olentangy flow were moved simply south the Antrim Park throughout the construction of path 315.

You are watching: How deep is the olentangy river

Traffic thunders follow me State route 315 in between downtown Columbus and also I-270 North. Running alongside is a well-known bike trail and beside it, theOlentangyRiver.

Listener Valerie Mattingley rides the bike trail often.

"I am a volunteer v the MetroParks," Mattingley says. "I heard from somebody at the MetroParks that portions of the Olentangy river were moved when path 315 to be being built. And I’ve constantly been curious what sections to be moved and why."

The brief answer is “Yes.” That’s words from Breanna Badanes in ~ the Ohio department of Transportation.

The Olentangy, she says, was rerouted at the I-270 Interchange and just southern of Antrim Park. But, Badanes says, there’s no one left at ODOT who can speak more specifically around the project, which dates ago to the 1960s.

So ns paid a visit come the offices of FLOW, girlfriend of the reduced Olentangy Watershed. That’s whereby I met Laura Fay, who pulled something the end of a library of historic maps indigenous 1902.

She found a map that reflects that, in ~ a allude just listed below present-day Antrim Park, the Olentangy transforms west, then south, then transforms east before resuming its southerly course. Fay compared the 1902 map v one from the 1960s.

"Honestly, that does look choose there have actually been transforms from 1902 come 1968," Fay says.


A map of course 315, out of a publication titled “State course 315: Ackerman roadway to interstate 270," shows the location where the Olentangy river was moved.
I want to watch first-hand if there was still a bend near Antrim, yet recent rains made canoeing the swollen river impossible. Laura Fay had actually a suggestion.

"George Anderson concerns mind," Fay said. "He’s a experienced photographer but fell in love through the river and also goes out canoeing rather a bit. He might be acquainted with this stretch."

He was an ext than familiar. Anderson has actually been canoeing the Olentangy because that over 30 years.

"Right there wherein 315 come in, just south that Antrim Park, that part of the river, I would certainly strongly suspect, to be either straightened the end or moved over to put in 315," Anderson says. "My knowledge is that once 315 was put in, numerous acres the wetlands to be filled in for 315 come be placed there."

That provides sense, because 315 is in ~ ground level near Antrim, quite than elevated, together it is in the college area. Anderson claims the bend in the river is gone; so is one more farther north.

Just listed below Antrim Park, the Olentangy flow was relocated at the expense of several acres of wetlands.
"The interchange at 270 and 315 took out, there to be a horseshoe or at the very least a bend that you may discover in old maps and so it was straightened out appropriate through there," Anderson says.

I discovered final check in one obscure volume housed in The Ohio State University’s style library, a publication titled “State course 315: Ackerman roadway to interstate 270.”

It consists of ODOT’s plan for creating Route 315, and also includes a ar titled “Probable Adverse ecological Effects the Cannot it is in Avoided.”

That report says virtually 22 acre of wetlands will certainly be lost, and also it shows that the river would certainly be shortened, native 2,300 feet of organic channel to 1,600 feet of synthetic channel.

Route 315 go indeed change the OlentangyRiver forever. But George Anderson claims you have the right to still find some solitude there.

"I can’t say that quiet," Anderson says. "I need to plug mine ears and not hear six lanes of highway. Yet actually come tell you the truth around Antrim Park, the amazingly quiet and also amazingly sylvan, would be the word I would use."
