Curtis is a privately owned dam located in Lackawanna, Pennsylvania, along the White Oak Run river. Built in 1887, this Earth type dam stands at a height of 45 feet and has a length of 203 feet. Its primary purpose is to supply water, with a storage capacity of 1632 acre-feet and a drainage area of 2.4 square miles. However, despite its historical significance, Curtis is currently deemed to have a high hazard potential and poor condition assessment.

Managed by the Pennsylvania Department of Environmental Protection, Curtis has undergone modifications in 2006. With a poor condition assessment and high hazard potential, this dam requires regular inspections to ensure its structural integrity and the safety of surrounding communities. Although its emergency action plan status and risk management measures are not specified, the dam's operational and regulatory status remains under state jurisdiction with enforcement and permitting responsibilities resting with the Pennsylvania authorities. For water resource and climate enthusiasts, Curtis presents an intriguing case study in the management and maintenance of aging infrastructure in the face of evolving environmental challenges.
