Zelina is a privately owned dam located in Elk Creek Township, Erie, Pennsylvania, along the TR CUSSEWAGO CREEK. Built in 1974 with a primary purpose of recreation, this Earth-type dam stands at a height of 15 feet and has a length of 1100 feet, providing a storage capacity of 154 acre-feet. The dam is regulated by the Pennsylvania Department of Environmental Protection and undergoes regular inspections, with the last one conducted in March 2021.

With a significant hazard potential, Zelina is an important structure for water resource and climate enthusiasts to monitor. The dam's condition assessment is currently not rated, highlighting the need for continued attention to its maintenance and safety. The dam was modified in 2007 for hydraulic improvements, and its emergency action plan status is yet to be determined, making it crucial to ensure preparedness in case of any unforeseen events. As a key recreational feature in the area, Zelina serves both practical and leisure purposes, offering opportunities for outdoor activities while also playing a vital role in water management.

As part of the Buffalo District in Pennsylvania, Zelina contributes to the local landscape and water infrastructure, with a storage capacity of 95 acre-feet for normal operations. Its location in a picturesque setting makes it a popular spot for visitors, but the dam's hazard potential underscores the importance of ongoing monitoring and maintenance. With its Earth-type construction and buttress core, Zelina stands as a testament to engineering expertise and the intersection of human activity with natural resources, making it a fascinating site for water resource and climate enthusiasts to explore and study.
