SECURING OUR WATER FUTURE

A Generational Investment in
Douglas County

A MESSAGE FROM THE EXECUTIVE DIRECTOR

The Dog River Reservoir represents years of planning and investment to ensure Douglas County is prepared for the future. As our community continues to grow, having a reliable water supply is essential for both our residents and the businesses that choose to plant their lives here.

This project has been decades in the making and reflects the long-term vision to ensure Douglas County has a safe and dependable water supply long into the future, especially during times of increasingly worse droughts in our area.

While we have to endure some growing pains as we build this project, we are excited about having it completed in 2029 and once again opening our refreshed and modernized Recreation Area to our residents and businesses to enjoy the beautiful reservoir.

Investments like this position our community for the next 50 years and beyond, allowing us to meet future demand while maintaining reliable service.

“The Dog River Reservoir is more than a water source—it’s an investment in the future of Douglas County and the quality of life for generations to come.” – Gilbert Shearouse
