The Northfork Recreational Territories Dam in Allamakee, Iowa, is a privately owned structure designed by NRCS and completed in 1995. This earth dam stands at a height of 12 feet and stretches 1380 feet in length, creating a reservoir with a storage capacity of 73 acre-feet. The dam serves multiple purposes, including recreation, and is regulated by the Iowa Department of Natural Resources with state permitting, inspection, and enforcement in place to ensure its safety and compliance.

Situated on the TR-Teeple Creek, the Northfork Dam offers opportunities for outdoor activities in the scenic MARQUETTE area, with a low hazard potential and a moderate risk assessment rating of 3. Despite not being rated for its condition, the dam has not undergone any major modifications since its construction. The surrounding area boasts a surface area of 9.8 acres and a drainage area of 0.05 square miles, making it a valuable resource for water and climate enthusiasts interested in conservation and recreational opportunities within the St. Paul District.

While the dam does not feature a controlled spillway, its uncontrolled design aligns with its low hazard potential. With its location in a picturesque setting and its importance for both water resource management and recreational activities, the Northfork Recreational Territories Dam stands as a noteworthy example of private ownership contributing to the sustainable use of water resources in Iowa.
