Summary
15, located in Thief River Falls, Minnesota, is a federal-owned earth dam with a primary purpose classified as 'Other'. Completed in 1960, this dam measures 8 feet in height and spans a length of 6000 feet, with a maximum storage capacity of 5597 acre-feet. With a low hazard potential and a condition assessment of 'Not Rated', Pool No. 15 serves the Thief River-TR area and plays a crucial role in water resource management within the region.
Despite not being state-regulated or having state jurisdiction, Pool No. 15 is closely monitored by the Omaha District of the US Army Corps of Engineers. With a maximum discharge capacity of 100 cubic feet per second and an inspection frequency of 8 years, this dam maintains a safe operational status. Although its emergency action plan and risk assessment details are not readily available, the dam's low hazard potential indicates a lower likelihood of significant safety concerns.
In summary, Pool No. 15 in Marshall County, Minnesota, is a vital earth dam structure that provides crucial water resource management for the surrounding area. With its solid construction, ample storage capacity, and low hazard potential, this dam contributes to the overall environmental sustainability and climate resilience of the region.

Condition Assessment
SatisfactoryNo 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. Note: Rare or extreme event is defined by the regulatory agency based on their minimum
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. Investigations and studies are necessary.
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.
Not Available
Dams for which the condition assessment is restricted to approved government users.
Hazard Potential Classification
HighDams 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, environment 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.
Not Available
Dams for which the downstream hazard potential is restricted to approved government users.
