Summary
Constructed in 1966 by the USDA NRCS, this dam serves multiple purposes including fire protection, stock watering, and small fish pond management. With a height of 23 feet and a length of 350 feet, the dam has a storage capacity of 50 acre-feet and covers a surface area of 4 acres.
Situated on the Sheyenne River, Howey Dam plays a crucial role in regulating water flow and providing essential resources to the surrounding area. Despite being classified as a low hazard potential structure, the dam is regularly inspected and maintained to ensure its structural integrity and safety. The spillway, with a width of 55 feet, is designed to handle uncontrolled releases during periods of high water flow.
Water resource and climate enthusiasts will appreciate the strategic location and design of Howey Dam, which contributes to the overall water management system in the region. With a moderate risk assessment rating and a focus on risk management measures, this dam exemplifies the importance of sustainable infrastructure development for both human and environmental well-being. As a key component of the local water infrastructure, Howey Dam continues to play a vital role in water resource management and ecosystem preservation.

Dam Data Reference
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.
