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.


2020 Events

7th Annual NOW Festival
The NOW Festival for June 20th was canceled. 2021’s tentative date is June 26th. I am working on potentially organizing a virtual watershed program where the public can view various demonstrations (on rain barrels, river samplings, fish identification, stormwater pollution etc.) and may try to get something posted to the page about it later.

Event Schedule
For more information email Caroline Cicerchi.

Rain Barrels

  • The City of Delaware Public Utilities offers discounted rain barrels year-round to residents, in coordination with its Small Municipal Storm Sewer System (MS4) Permit with the Ohio EPA. The barrels vary in color and size based on what is in stock. To purchase a barrel, please contact the Watershed Coordinator.
  • Rain barrels connect to downspouts and store rainwater for reuse. There are many benefits to them including reducing stormwater runoff, watering gardens, and lowering water bills.
  • Rain barrels can also be the perfect canvas for works of art. Every June, a rain barrel raffle takes place during the NOW Festival, with over a dozen locally painted barrels raffled off. Are you interested in showing off your art skills or have an interest in sponsoring a barrel on behalf of a local painter? Reach out to the Watershed Coordinator.
  • Each summer, rain barrel installation demonstrations are offered during First Fridays, typically in May and June. Watch for more information on these on this page, or on the Public Utilities Facebook Page.
  • More information on rain barrels can be found here

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.


The Delaware, Knox, Marion, Morrow Joint Solid Waste District
The City of Delaware is part of the DKMM district, a political subdivision funded by a fee on solid waste generated within the district. DKMM funds programs that provide education about and alternatives to disposal of generated wastes.  These programs include: recycling, composting, education and awareness, solid waste environmental and monitoring and household hazardous waste, electronics and tire collections.  DKMM Special Collection Events
