Tillis #1 is a private earth dam located in Cheatham, Tennessee, with a primary purpose of providing fire protection, stock, or a small fish pond. Built in 1981, this dam stands at a hydraulic height of 25 feet and a structural height of 31 feet, allowing for a maximum storage capacity of 129 acre-feet. Despite its relatively low hazard potential and moderate risk assessment, Tillis #1 has not been rated for its condition.

Situated along Tributary Sycamore Creek in the Nashville District, Tillis #1 serves as a vital resource for the local area, covering a surface area of 9.1 acres. While the dam is designated as uncontrolled spillway type, it remains subject to periodic inspections every five years, with the last assessment conducted in May 2016. The condition of the dam is not currently rated, and there are no emergency action plans in place, indicating a need for further evaluation and risk management measures to ensure the safety and reliability of this critical water resource infrastructure.

With its strategic location and essential functions for fire protection and water storage, Tillis #1 underscores the importance of proactive monitoring and maintenance of dams in the region. As climate change continues to pose challenges to water resource management, it becomes increasingly crucial to prioritize the safety and resilience of infrastructure like Tillis #1 to mitigate potential risks and safeguard the surrounding communities and ecosystems from the impacts of extreme weather events and changing hydrological conditions.
