Summary

Completed in 1976, this earth dam stands at a height of 27 feet and has a length of 450 feet, with a storage capacity of 51 acre-feet. Situated on TR-Pony Creek, this dam plays a crucial role in providing water for irrigation and other purposes in the area.

Despite being privately owned, the dam is subject to state permitting, inspection, and enforcement. The absence of a spillway and emergency action plan raises concerns about its hazard potential, with a risk assessment rating it as high. The condition of the dam is not currently rated, highlighting the importance of continued monitoring and maintenance to ensure its safety and reliability in the face of potential climate challenges.

Water resource and climate enthusiasts can appreciate the significance of Brock Lake No 2 Dam in managing water resources for irrigation in the region. Its location, design, and capacity all contribute to its importance in sustaining agricultural activities and water supply. However, the dam's risk assessment underscores the need for proactive measures to address potential hazards and ensure its long-term functionality amid changing climatic conditions.

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.
