Summary
Completed in 2002, this earth dam stands at a height of 33 feet with a structural height of 27 feet and a length of 630 feet. It has a maximum storage capacity of 43 acre-feet and a drainage area of 52 square miles, serving as a vital infrastructure for water resource management in the region.
With a low hazard potential and a moderate risk assessment rating, Kirby Rosier Dam plays a crucial role in mitigating flood risks and maintaining the stability of the surrounding area. The dam features an uncontrolled spillway with a width of 39 feet and has not been rated for its current condition. While it does not have outlet gates, the dam has no state-regulated permitting, inspection, or enforcement requirements, reflecting its private ownership status and operational independence.
For water resource and climate enthusiasts, Kirby Rosier Dam presents an intriguing case study in private dam ownership and management. Its construction by the Natural Resources Conservation Service showcases innovative approaches to grade stabilization, while its low hazard potential and moderate risk assessment highlight the importance of ongoing monitoring and maintenance. As a key component of the local water infrastructure, this earth dam contributes to the overall resilience and sustainability of the region's water resources in the face of changing climatic conditions.

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.
