Tie Hack is a concrete dam located in Johnson County, Wyoming, along the South Fork Clear Creek. Built in 1997 by designer Victor E. Anderson, the dam stands at a height of 110 feet and has a length of 500 feet, providing a storage capacity of 2,435 acre-feet for water supply purposes. The dam's primary purpose is water supply, with additional functions including hydroelectric power generation.

With a high hazard potential and fair condition assessment as of August 2018, Tie Hack is regulated by the Wyoming State Engineer's Office and undergoes regular inspections every five years. The dam is equipped with an uncontrolled spillway and four slide (sluice gate) outlet gates. Despite its moderate risk assessment, the dam serves as a critical infrastructure for managing water resources in the region and plays a key role in ensuring water availability for the surrounding communities.

Located in a picturesque setting near Buffalo, Wyoming, Tie Hack stands as a testament to engineering excellence and the importance of sustainable water resource management. As climate change continues to impact water availability and quality, Tie Hack serves as a vital piece of infrastructure in the region's efforts to adapt and mitigate the effects of a changing climate on water resources.
