Summary
This earth dam stands at a height of 16.5 feet and has a storage capacity of 126 acre-feet, with a surface area of 19 acres and a drainage area of 10 acres. The dam regulates Sand Creek-TR and is operated and regulated by the North Dakota State Water Commission (NDSWC).
Despite being classified as having a low hazard potential, Temvik Dam is subject to state regulation, inspection, and enforcement, with the last inspection conducted in May 2018. The dam has an uncontrolled spillway with a width of 60 feet, and no outlet gates or locks. The risk assessment for the dam is rated as moderate, with a DSAC assigned date of none. While the condition assessment is not rated and the Emergency Action Plan (EAP) status is unclear, the dam continues to serve its purpose effectively for the local community.
Temvik Dam, situated in a picturesque location in North Dakota, stands as a testament to the CCC's craftsmanship and dedication to water resource management. With its historic significance and ongoing functionality for fire protection and irrigation purposes, the dam remains a valuable asset for the region. Climate and water resource enthusiasts can appreciate the engineering marvel of Temvik Dam and its contribution to the local ecosystem while also recognizing the importance of ongoing maintenance and regulation to ensure its continued safety and effectiveness.

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.
