Sweet Pond Dam

Guilford, Vermont | Vermont Dept. of Forests, Parks and Recreation

Sweet Pond Dam is a 20-ft-high by 77-ft-long circa-1928 dam that impounds an 18-acre pond with a contributing drainage area of approximately 1 square mile. The dam sustained uncontrolled and excessive seepage through highly fractured and weathered bedrock and posed a barrier to AOP. D&K provided planning, evaluation, alternatives analysis, preliminary and final design, permitting assistance, and construction administration and observation services. The design included a structurally independent concrete cutoff wall with post-tensioned bedrock anchors, a new concrete cap along the principal spillway, scour protection downstream of the dam, recreational improvements, and AOP design for American Eel passage.
