Summer Clean-ups Planned for Several Areas in Dubuque, Iowa Everyone says they are for a cleaner Dubuque. But if you've looked around our city lately, apparently not everyone got the memo. If you have a little extra time and would like to do your part to keep our All America City clean, here's your chance. The City of Dubuque, Dubuque Metropolitan Area Solid Waste Agency, Green Iowa AmeriCorps, and the National Mississippi River Museum & Aquarium have partnered to host the 2021 Tri-Basin Summer Clean-Up Series. The series is part of an ongoing effort to create healthier and safer watersheds, preserve our natural resources, and promote watershed stewardship.
