Summary
This private dam on the TR Rocky Hollow stream has a dam height of 19 feet and a storage capacity of 93 acre-feet. With a surface area of 8 acres and a drainage area of 365 square miles, the dam serves multiple purposes including fire protection, stock, small fish ponds, irrigation, and recreation.
Despite being privately owned and not regulated by the state, D & R Laker Lower Dam is classified as having a high hazard potential. The condition assessment of the dam is currently not rated, and there is no information available on emergency action plans, risk assessments, or risk management measures. While the dam has not been inspected recently, it is important for water resource and climate enthusiasts to monitor the safety and maintenance of such structures to prevent potential hazards and ensure the sustainability of water resources in the area.
This dam serves as a critical infrastructure for agricultural irrigation in the region and plays a significant role in water management. Understanding the importance of maintaining and monitoring dams like D & R Laker Lower Dam is crucial for ensuring the safety of surrounding communities and the sustainable use of water resources. With its high hazard potential, it is essential for stakeholders to prioritize inspections, risk assessments, and emergency preparedness to mitigate any potential risks associated with the dam.

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.
