Summary
14 is a federal-owned earth dam located in Thief River Falls, Minnesota. Built in 1960, this dam stands at a height of 9 feet and spans a length of 4000 feet, providing a storage capacity of 4525 acre-feet. The primary purpose of Pool No. 14 is listed as "Other," with low hazard potential and a condition assessment of "Not Rated."
Situated on the Thief River, Pool No. 14 serves as an essential water resource structure in Marshall County, Minnesota. With a maximum discharge capacity of 70 cubic feet per second, this dam plays a crucial role in managing the water levels and ensuring the safety of the surrounding area. Although not state-regulated, Pool No. 14 remains an important part of the local water infrastructure.
Managed by the Omaha District of the US Army Corps of Engineers, Pool No. 14 is a key component of the region's flood control and water management system. Despite its low hazard potential, regular inspections are conducted every 8 years to assess its condition and ensure its continued functionality. This dam serves as a testament to the importance of water resource management in the face of changing climate conditions.

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.
