English Coulee Dam, located in Grand Forks, North Dakota, was completed in 1990 by the USDA NRCS with a primary purpose of flood risk reduction along the English Coulee river. This earth dam stands at a height of 27 feet and spans 36,960 feet in length, providing a storage capacity of 29,200 acre-feet to mitigate potential flooding in the area. With a spillway width of 200 feet and a high hazard potential, the dam is regulated by the NDSWC and undergoes regular state inspections to ensure its structural integrity.
Despite its satisfactory condition assessment, English Coulee Dam presents a moderate risk level of 3, according to the data. The dam features a stone core and soil foundation, with one slide (sluice gate) outlet gate for water management. The dam is state-regulated for permitting, inspection, and enforcement, underlining the importance of its role in managing floodwaters and protecting the surrounding communities. In case of emergencies, the dam is equipped with an emergency action plan, although details on its preparedness and adherence to guidelines are not specified in the available information.
Overall, English Coulee Dam serves as a crucial infrastructure for flood risk reduction in the region, supported by the local government and designed by the USDA NRCS. With a focus on public safety and water resource management, the dam plays a vital role in safeguarding against potential inundation and ensuring the resilience of the surrounding areas in facing climate-related challenges. As a significant structure in the Omaha District, English Coulee Dam exemplifies the intersection of engineering, environmental conservation, and climate resilience for water resource enthusiasts to appreciate and study.
