Spirit is a historic hydroelectric dam located in Lincoln, Wisconsin, along the Spirit River. Built in 1922, this gravity dam stands at a height of 26 feet and has a length of 2530 feet. With a storage capacity of 15,427 acre-feet and a maximum discharge of 16,700 cubic feet per second, Spirit serves multiple purposes including flood risk reduction and hydroelectric power generation.

Managed by the Federal Energy Regulatory Commission, Spirit has a controlled spillway and two Tainter radial gates for outlet control. Despite its age, the dam is categorized as having a high hazard potential and a very high risk assessment. While regular inspections are conducted, the condition assessment is currently not available, highlighting the need for ongoing monitoring and maintenance to ensure the safety and functionality of this critical water resource infrastructure.

For water resource and climate enthusiasts, Spirit represents a fascinating blend of history, engineering, and environmental management. As a key player in the region's water management system, Spirit serves as a reminder of the intricate balance between harnessing water for energy production and mitigating the risks associated with dam infrastructure. With its high hazard potential and risk assessment, Spirit underscores the importance of proactive risk management strategies to safeguard both the environment and surrounding communities in the face of changing climate conditions.
