BACKGROUND: The focus of this General Investigations feasibility study will be to reassess feasible structural and nonstructural measures to reduce flood risk for the city of Watertown. A planning charrette was held between USACE and the city of Watertown on Oct. 18-19, 2022, to discuss flooding history, problems and opportunities, and formulate potential measures to be combined into alternatives. Structural measures formulated during this charrette preliminarily included a traditional dam and reservoir, dry dam, underground diversion, channel widening, floodproofing and nonstructural measures, and wetland-riparian habitat complexes. These measures were evaluated against screening criteria that included public acceptability, environmental impacts, operation and maintenance, constructability, and how each measure would benefit properties in Watertown, Lake Kampeska, Pelican Lake, and the climate resiliency of each measure. These measures will be further analyzed by the team and combined into alternative plans or screened from analysis. As part of this GI, the USACE will conduct an Environmental Assessment in accordance with the National Environmental Policy Act to analyze potential environmental and social effects any proposed actions would have.
