Volunteers are encouraged to participate in this annual litter cleanup on Saturday, September 14, 2013 from 9 a.m. - 12 p.m. at Hoover Reservoir.

New signage installed this year at Griggs, O'Shaughnessy & Hoover Reservoirs invites park visitors to learn about the green infrastructure installed there. Columbus is using green infrastructure to improve the quality of storm water entering the reservoirs that supply our drinking water.

Columbus provides a variety of services to protect both surface & drinking water quality. We work with communities upstream to help reduce the impact of agricultural activities. In our own community, we partner with landowners adjacent to our reservoirs and monitor construction sites to limit sedimentation that can impact local waterways. We also protect the quality of life downstream by discharging clean water from our wastewater treatment plants.
