Summary
Built in 2003 by USFWS, this earth dam serves multiple purposes including fire protection, stock, and small fish pond. With a height of 21 feet and a storage capacity of 140.65 acre-feet, the dam plays a crucial role in managing water resources in the area.
Situated on Timber Creek, Gall Dam covers a surface area of 11.5 acres and has a drainage area of 0.67 square miles. The spillway type is uncontrolled with a width of 50 feet, ensuring proper water flow during high rainfall events. Despite its low hazard potential, the dam is regulated and inspected by the North Dakota State Water Commission to ensure its safety and functionality.
With a risk assessment rating of moderate, Gall Dam is equipped with appropriate risk management measures to mitigate any potential issues. While its condition is currently not rated, the dam serves as a valuable asset for fire protection and water storage in the region. As a significant feature in the St. Paul District of the USACE, Gall Dam stands as a testament to effective water resource management and climate resilience efforts in North Dakota.

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.
