Thriving communities, a healthy watershed, and a higher quality of life, sustained by well-managed water resources throughout the watershed.
Protecting lives, property and economic vitality within the Great Miami River Watershed through an integrated and balanced system that provides unfailing flood protection, preserves water resources, and promotes enjoyment of our waterways.
People and businesses along the Great Miami River in southwest Ohio enjoy life without flooding concerns. MCD’s system of five dry dams, basins, 55 miles of levees, and preserved floodplain provide a nearly unparalleled level of protection.
Our Main District is responsible for an integrated flood protection system that significantly reduces flood risk from the Great Miami River in cities from Piqua to Hamilton. MCD has developed and built five dry dams and 55 miles of levee and has preserved thousands of acres of floodplain. Together, the dams have stored floodwaters more than 1,900 times since construction was completed in 1922. MCD has reinvested in the dams and levees over the years to ensure the system’s integrity for future generations. MCD’s flood protection is known around the U.S. and the world. Officials from other states and countries have visited to learn more about it. Today, MCD has more than 20 people dedicated to the daily operations, maintenance, and inspection of the system.
Water is the key to healthy people and healthy communities. We monitor and protect our region’s water.
Our Aquifer Preservation Subdistrict supports stewardship of the region’s water resources. MCD’s water stewardship efforts work to protect and improve the quantity and quality of water for people living and working within the Great Miami River Watershed.
MCD’s non-regulatory role focuses on technical data, analysis, and expertise. Staff collects data along area rivers and aquifers, hosts events and educational programs, and builds awareness of water and water-related causes. MCD collaborates with elected officials and community leaders, providing them with valued insight to support the region’s overall health, vitality, and growth.
And water isn’t just for drinking. Rivers are outdoor playgrounds. MCD is working to bring more and more people to the river.
Our River Corridor Improvement Subdistrict enhances public use and enjoyment of river corridors by utilizing improvements, amenities, and activities within and along the river corridors. Whether you like to fish, paddle or cycle, you’ll find plenty of opportunity in the Dayton region. More than 40 years ago, MCD built the first 8-mile bike trail loop in downtown Dayton – a trail segment that has become the backbone of the largest paved trail network in the country, with 340 miles. And the region boasts more than 290 miles of rivers and streams to fish and paddle. These waterways are so awesome, they’ve been designated by the state of Ohio as well as nationally by the U. S. Department of the Interior for their excellence. Download a copy of one of our river recreation maps to show you the best places to get onto the river. Or request a bike map.
