Welcome to your Ottawa River.

The Ottawa River flows through Allen and Hardin Counties, past farms, neighborhoods and city streets. It is a living, vital river that shapes our landscape and our lives. The Ottawa River Coalition was formed to preserve and protect the river; and dozens of businesses, industries, governments, organizations and individuals work together toward that common goal. The Ottawa River is healthier now than it has been in decades because people are making positive impacts. A healthy river supports a healthy community. This is your river. What are you doing to protect it?

Join hundreds of your friends and neighbors on September 7 for the annual Ottawa River Cleanup. It’s a fun day and great way to truly make a positive impact on the Ottawa River.
