Summary
Built in 1993 by the USFWS, this dam serves as a Fish and Wildlife Pond with a storage capacity of 91.7 acre-feet. The dam stands at 10.8 feet in height and has a spillway width of 100 feet, operating with an uncontrolled spillway type. The primary purpose of Jorda Dam is to support fish and wildlife conservation efforts in the area.
Managed by the North Dakota State Water Commission, Jorda Dam is considered to have a low hazard potential and a moderate risk assessment rating. While its condition assessment has not been rated, the dam is regularly inspected, permitted, and enforced by state regulatory agencies. With a drainage area of 5.4 square miles and a surface area of 9.4 acres, Jorda Dam plays a crucial role in managing water resources and supporting the local ecosystem.
Despite being a smaller dam, Jorda Dam's contribution to fish and wildlife conservation in the region is significant. As a vital part of the Cedar Creek-TR watershed, this dam not only provides essential water storage but also helps in maintaining the ecological balance of the area. With its strategic location and purpose, Jorda Dam stands as a testament to the importance of sustainable water resource management in mitigating the impacts of climate change on wildlife habitats.

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.
