Summary
Completed in 1990, this Earth-type dam stands at a height of 15 feet and spans 796 feet in length, with a primary purpose of serving as a Fish and Wildlife Pond. With a normal storage capacity of 89 acre-feet and a maximum storage of 332 acre-feet, this dam plays a crucial role in water resource management in the region.
The dam's low hazard potential and fair condition assessment make it a reliable infrastructure for flood control and water storage, contributing to the conservation efforts of the Fish and Wildlife Service. It is regulated by the state agency NDSWC and undergoes regular inspections to ensure its structural integrity and operational efficiency. The dam's location in a drainage area of 14.8 square miles and its close proximity to the TR river underscores its significance in protecting the surrounding ecosystem and supporting wildlife habitat.
Despite its modest size, G19a Dam plays a vital role in maintaining water quality and biodiversity in the area. With controlled outlet gates and a spillway width of 147 feet, this dam is equipped to handle a maximum discharge of 1777 cubic feet per second. Its strategic design and management by the Fish and Wildlife Service highlight the importance of sustainable water resource management practices in the context of climate change and increasing water scarcity.

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.
