The Olentangy River Watershed
The Olentangy River flows 88.5 miles from its headwaters in Crawford and Richland County through Marion and Morrow County into the City of Delaware and ending in Franklin County at its confluence with the Scioto River. The Olentangy River has a drainage area of 536 square miles. Twenty-two miles of the Olentangy were designated a state Scenic River by the Ohio Department of Natural Resources in 1973. The designation runs from the Delaware Dam, north of the City, to the old Wilson Bridge Road in Worthington.

Olentangy River Watershed Success Stories

Olentangy River Clean-up: August 24, 2019

The City of Delaware Public Utilities Department, Keep Delaware County Beautiful, and the Ohio EPA partnered for the annual river clean-up. T-shirts were provided to participants from the EPA grant that was awarded. TranSystems donated snacks and refreshments to the program.

  • A total of 74 volunteers attended
  • 2,200 pounds of trash collected
  • 12 tires (including some shredded pieces) total
  • Roughly 65 bags of trash collected
  • 860 lbs of scrap metal recycled to Sims Brothers, which generated $42.47 that was donated to the Olentangy Watershed Alliance.

Bio-Retention Cells on OWU Campus
Two bio-retention cells were installed in Spring 2018 on the campus of Ohio Wesleyan University, near Branch Rickey Arena. Bio-retention cells are stormwater utilize soil, mulch and vegetation to treat runoff from impervious surfaces such as rooftops, sidewalks and roadways. All species in the gardens are native to Ohio, which minimizes the need for maintenance, watering and pesticides. The plants have a high moisture and pollutant tolerance that will allow for the uptake of nutrients. The flowers were carefully selected by city staff to attract a diversity of wildlife including Monarch butterflies, bees, hummingbirds and other pollinator species. The project was funded through the City’s storm water fund in compliance with with Ohio EPA.
