Summary

Completed in 1977, this dam serves a primary purpose that is classified as "Other," with a normal storage capacity of 480 acre-feet and a maximum storage of 720 acre-feet. The dam has a hydraulic height of 13 feet and a length of 335 feet, providing vital water resource management for a drainage area of 1.4 square miles.

Despite being rated as having low hazard potential, Round Corral Dam (Blm) has not been recently assessed for its condition, with the last inspection conducted in September 2015. The dam is not regulated by the state and does not have an Emergency Action Plan (EAP) in place. With no designated risk management measures identified, there is a need for increased oversight and preparedness to ensure the safety and functionality of this important water infrastructure in the event of an emergency.

As an enthusiast of water resources and climate, the data on Round Corral Dam (Blm) presents an opportunity for further investigation into the dam's structural integrity, emergency preparedness, and overall impact on the surrounding environment. By examining the dam's history, purpose, and current condition assessment, stakeholders can work towards implementing necessary risk management measures and ensuring the long-term sustainability of this critical water resource infrastructure.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
