The Little Conowingo Creek stream restoration project for the Donegal Chapter of Trout Unlimited addressed severe erosion and habitat deficiencies along a stream in Fulton Township. RETTEW prepared a comprehensive natural stream design solution involving channel realignment and the strategic installation of various structures, including rock cross vanes, rock weirs, boulder walls, rock deflectors, and floodplain benches to restore sediment transport and natural flow patterns. Our approach prioritized the environmental preservation of large trees, wetlands, and riparian forested buffers.

RETTEW also secured all necessary permitting and easements and provided construction oversight. This holistic approach, covering approximately 3,372 feet of stream restoration and forest buffer installation, is projected to yield significant pollutant load reductions annually, including 252.9 pounds of nitrogen, 229.3 pounds of phosphorus, and a remarkable 151,335.36 pounds of sediment reduction, based on MS4 default rates. Through meticulous planning and execution, our efforts provided a sustainable solution, safeguarding this reach of Little Conowingo Creek. This project was funded by a federal Section 319 Grant from the U.S. Environmental Protection Agency and the Pennsylvania Department of Environmental Protection and is part of an ongoing effort to restore the Conowingo Creek Watershed.
