Summary
Completed in 1969, this earth dam stands at a height of 18 feet and boasts a storage capacity of 259 acre-feet. Its primary purpose is water supply, with a normal storage capacity of 150 acre-feet, making it a vital resource for the local community.
Despite not having a spillway, the dam has been deemed to have a high risk potential, indicating the importance of regular inspections and maintenance to ensure its structural integrity. With a lack of regulatory oversight from state agencies and a hazard potential that is not available, there is a need for increased attention to be paid to the risk management measures in place for this dam. The presence of one outlet gate suggests a degree of control over water release, but further details on emergency preparedness and response protocols are not readily available.
Situated on TR-El Jaral Creek and managed by a private entity, L E Bruni Lake No 1 Dam stands as a critical infrastructure for water resource management in the area. Its age and risk potential warrant continued monitoring and assessment to mitigate any potential hazards and ensure the safety and reliability of this essential water supply source.

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.
