Summary
Built in 1964 by the Natural Resources Conservation Service, this dam stands at 19 feet in height and has a storage capacity of 84 acre-feet. It is situated on the Tr-West Plum Creek, with a drainage area of 1.61 square miles and a maximum discharge rate of 2770 cubic feet per second. Despite its low hazard potential, the dam has a moderate risk assessment rating.
This dam plays a crucial role in water resource management in the region, serving multiple purposes such as fire protection and stock watering. With a spillway width of 132 feet and uncontrolled spillway type, it is designed to release excess water and prevent flooding downstream. Although its condition assessment is currently not available, ongoing inspections and risk management measures are likely in place to ensure the safety and integrity of the structure. As climate change continues to impact water resources, the maintenance and monitoring of dams like Sd No Name 263 are essential for adapting to evolving conditions and mitigating risks.
In the event of an emergency, the dam's emergency action plan (EAP) status is not available, highlighting the need for preparedness and communication protocols. With its location in a rural area and moderate risk level, it is important for relevant agencies and stakeholders to stay engaged in monitoring and maintaining Sd No Name 263. By prioritizing water resource management and climate resilience, this dam can continue to play a vital role in supporting the surrounding community and ecosystems.

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.
