Shogren is a Federal-owned dam located in Itasca, Minnesota, along the TR-BOWSTRING RIVER. Completed in 1986 by the USDA Forest Service, this Earth-type dam serves the primary purpose of creating a Fish and Wildlife Pond. With a dam height of 8 feet and a length of 600 feet, Shogren has a storage capacity of 1594 acre-feet and a drainage area of 5 square miles. Despite its low hazard potential, the dam has a moderate risk assessment rating, indicating the need for ongoing monitoring and management measures.

Although Shogren has not been rated for its condition, it underwent structural modifications in 1986. The dam has an uncontrolled spillway type and a maximum discharge capacity of 7000 cubic feet per second. The last inspection was conducted in June 2017, with a scheduled inspection frequency of every 10 years. While an Emergency Action Plan (EAP) has not been prepared, the dam is equipped with emergency contacts, and its risk assessment suggests a moderate level of risk that should be addressed through appropriate risk management measures. Overall, Shogren is an important water resource infrastructure supporting fish and wildlife conservation efforts in the area.

Given its location and purpose, Shogren represents a vital component of the local ecosystem and water management infrastructure in Minnesota. As climate change continues to impact water resources and ecosystems, maintaining the safety and functionality of dams like Shogren becomes increasingly important. Continued monitoring, inspection, and risk management efforts will be crucial to ensure the long-term sustainability and effectiveness of this Federal-owned structure for the benefit of both wildlife and the surrounding community.
