Summary
Built in 1999 by USFWS, this earth dam stands at a height of 14.8 feet and has a length of 505 feet. With a storage capacity of 127.2 acre-feet and a surface area of 15.2 acres, Bland Dam serves multiple purposes including fire protection, stock watering, and as a small fish pond.
Managed by the North Dakota State Water Commission, Bland Dam is regulated, permitted, inspected, and enforced by the state agency. The dam has an uncontrolled spillway with a width of 80 feet and uses vertical lift outlet gates. Despite being rated as low hazard potential, the dam's condition is currently not assessed. The risk assessment for Bland Dam indicates a moderate risk level (3), highlighting the importance of ongoing monitoring and management measures to ensure its safety and functionality for the surrounding area.
In the picturesque setting along Cedar Creek-TR, Bland Dam plays a vital role in water resource management and climate resilience in the region. With its strategic location and diverse uses, this dam serves as a valuable asset for fire protection, irrigation, and wildlife habitat enhancement. As enthusiasts of water resources and climate sustainability, Bland Dam stands as a symbol of responsible stewardship and the importance of safeguarding our natural resources for future generations.

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.
