Harwood Lake Dam, located in Mount Holly, North Carolina, was completed in 1961 for the primary purpose of recreation. This private dam on Catawba River-Os stands at a structural height of 25 feet with a hydraulic height of 22 feet. It has a storage capacity of 58 acre-feet and a drainage area of 77 square miles, making it a significant feature in the region's water resource management.

Despite its age, Harwood Lake Dam has a low hazard potential and has not been rated for its current condition. The dam is state-regulated by the North Carolina Department of Environmental Quality's Dam Safety Program, ensuring that it undergoes regular inspections and enforcement measures to maintain its integrity. The last inspection was conducted in January 2019, with a frequency of every five years to assess any potential risks or hazards associated with the structure.

With its picturesque location and contribution to the local water system, Harwood Lake Dam serves as both a recreational hotspot and a vital component of water resource management in Mecklenburg County. As climate change continues to impact water availability and quality, the importance of maintaining and regulating dams like Harwood Lake becomes increasingly crucial in ensuring the sustainability and resilience of our water resources for future generations.
