Hatchery, also known as North Pond, is a privately owned dam located in Marinette, Wisconsin. This gravity dam was completed in 1890 and serves primarily for recreational purposes. With a height of 12.3 feet and a hydraulic height of 9 feet, Hatchery has a storage capacity of 600 acre-feet and a surface area of 70 acres.

Despite its low hazard potential and fair condition assessment, Hatchery poses a very high risk due to its age and the lack of recent updates or emergency preparedness measures. The dam has been inspected every 10 years, with the last assessment conducted in June 2020. The risk of inundation and the overall risk management measures for Hatchery remain unclear, highlighting the importance of continued monitoring and maintenance efforts to ensure the safety and integrity of this vital water resource in the North Branch Pike region.
