The work will involve mixing and pouring concrete into simple fiberglass molds, the “hatching” of the balls after the concrete has cured, and a general cleanup. This is a hands-on event suitable for anyone over the age of 16. Lunch and water will be provided. The Maryland Artificial Reef Initiative, Maryland-National Capital Park and Planning Commission, Wetland Studies and Solutions Inc., Fish America Foundation, Pro-Formance Fishing, and the Maryland Bass Nation are supporting partners in this project."
