Crowley, a privately owned hydroelectric dam located in Ladysmith, Wisconsin, has been a key player in harnessing the power of the North Fork Flambeau river since its completion in 1930. Standing at a height of 23 feet and with a maximum storage capacity of 3540 acre-feet, this gravity-type dam plays a crucial role in generating clean energy for the region. With a drainage area of 820 square miles and a maximum discharge capacity of 16,250 cubic feet per second, Crowley has proven to be a reliable source of renewable energy for decades.

Despite its age, Crowley remains a high-hazard structure with a very high risk assessment rating, highlighting the importance of regular inspections and maintenance. Managed by the Federal Energy Regulatory Commission, the dam features a controlled spillway with a width of 71 feet and two Tainter radial gates for water release. The surrounding area, with a surface area of 422 acres, is at risk of inundation in case of an emergency, emphasizing the need for a robust emergency action plan to mitigate potential risks.

Crowley continues to be a vital component of the local water resource infrastructure, serving as a prime example of sustainable energy generation through hydropower. With its historical significance and environmental impact, the dam stands as a testament to the intersection of water resource management, climate resilience, and renewable energy production in the modern era.
