Shogren dam
Shogren
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.

About Shogren
Where does the data for Shogren come from?
Structural and regulatory data come from the U.S. Army Corps of Engineers' National Inventory of Dams (NID). Weather forecast comes from NOAA / yr.no -- the same feed Snoflo's iOS app uses.
How often is the report updated?
NID structural data refreshes annually as the Corps publishes updated assessments. The weather forecast refreshes throughout the day.
What does the Low hazard rating mean?
The Corps of Engineers' hazard potential classification grades probable consequences if the dam fails: High = probable loss of human life; Significant = no probable loss of human life but possible economic loss / environmental damage; Low = no probable loss of human life, only minor economic / environmental losses. See the Dam Data Reference card below for the full definitions.
What's "% of normal"?
The current storage value compared to the historical average storage on this calendar day. 100% = right on average; values above 100% mean above-normal storage (wet year); values below mean below-normal (dry year or drought).
Can I get alerts when storage crosses a threshold?
Yes -- alerts are managed in the Snoflo iOS app. Favorite this dam, set a threshold, and you'll get a push the moment conditions cross.

Condition Assessment
- Satisfactory
- No existing or potential dam safety deficiencies are recognized. Acceptable performance is expected under all loading conditions (static, hydrologic, seismic) in accordance with the minimum applicable state or federal regulatory criteria or tolerable risk guidelines.
- Fair
- No existing dam safety deficiencies are recognized for normal operating conditions. Rare or extreme hydrologic and/or seismic events may result in a dam safety deficiency. Risk may be in the range to take further action.
- Poor
- A dam safety deficiency is recognized for normal operating conditions which may realistically occur. Remedial action is necessary. POOR may also be used when uncertainties exist as to critical analysis parameters which identify a potential dam safety deficiency.
- Unsatisfactory
- A dam safety deficiency is recognized that requires immediate or emergency remedial action for problem resolution.
- Not Rated
- The dam has not been inspected, is not under state or federal jurisdiction, or has been inspected but, for whatever reason, has not been rated.
Hazard Potential Classification
- High
- Dams assigned the high hazard potential classification are those where failure or mis-operation will probably cause loss of human life.
- Significant
- Dams assigned the significant hazard potential classification are those dams where failure or mis-operation results in no probable loss of human life but can cause economic loss, environmental damage, disruption of lifeline facilities, or impact other concerns. Significant hazard potential classification dams are often located in predominantly rural or agricultural areas but could be in areas with population and significant infrastructure.
- Low
- Dams assigned the low hazard potential classification are those where failure or mis-operation results in no probable loss of human life and low economic and/or environmental losses. Losses are principally limited to the owner's property.
- Undetermined
- Dams for which a downstream hazard potential has not been designated or is not provided.
