Take a Tour

Watershed Signage

Signage installed at Griggs, O'Shaughnessy & Hoover Reservoirs invites park visitors to  take a self-guided tour along the shoreline & learn about the green infrastructure installed there.

Rain gardens, porous pavement & more can improve the quality of storm water entering the reservoirs that supply our drinking water.

HooverWe provide a variety of services to protect surface water quality. Those services include a comprehensive approach to stormwater management, best management practices and a sediment and erosion control program for managing the impact of construction sites on local waterways. 

A proactive and comprehensive Watershed Management program also protects drinking water source quality. The department participates in the Conservation Reserve Enhancement Program (CREP), which is designed to help minimize the impact from agricultural activities occurring upstream. For property owners adjacent to our reservoirs, a Land Stewardship Program is in place to instill practices which have a positive impact on water quality while providing a nearly maintenance-free landscape.

Such cooperative efforts benefit the entire community, including future generations, wildlife and aquatic species.

We also protect the quality of life downstream of Columbus by discharging clean water from our wastewater treatment plants. Regulated by the Ohio EPA, we must meet the requirements of various permits including the National Pollutant Discharge Elimination System stormwater permit and the Safe Drinking Water Act.
