Volunteers are needed for the 44thAnnual Operation Clean Stream event on Saturday, August 27. Operation Clean Stream is one of the country’s largest and longest running river restoration projects. Volunteers clean the Meramec River and its tributaries, removing trash and debris from littering and dumping. Volunteers should arrive at Greentree Park in Kirkwood at 9 a.m. on August 27. They will be assigned to a section of the Meramec River at that time. There is no minimum age requirement as long as children are under adult supervision. All participants will be provided with gloves, trash bags, and a free t-shirt. Free lunch will also be available at the park. Volunteers can expect to finish up by 4 p.m. Volunteering is also a great opportunity for scouts to earn badges and students to earn community service hours. MSD is a sponsor of the 44th Annual Operation Clean Stream.
