Summary
Built in 2016 for grade stabilization purposes, this earth dam reaches a height of 24.9 feet and boasts a storage capacity of 58.9 acre-feet. With a controlled spillway and a low hazard potential, this structure plays a crucial role in managing water flow and mitigating flood risks in the TR-PUNCH river system.
Designed by Megan Baker and owned privately, Brian Collier dam is a key feature in the landscape of Bollinger County. Managed by the Natural Resources Conservation Service, this dam represents a collaboration between local stakeholders and federal agencies to ensure sustainable water management practices. Despite not being state-regulated, the dam's risk assessment classifies it as very high, emphasizing the need for ongoing monitoring and maintenance to uphold its structural integrity and functionality.
As climate change continues to impact water resources, the Brian Collier dam serves as a vital infrastructure for the community. With its stone core, soil foundation, and a surface area of 4.5 acres, this dam not only provides grade stabilization but also supports ecological diversity and water quality. As enthusiasts in water resource and climate adaptation, the Brian Collier dam stands as a symbol of resilience and collaboration in the face of environmental challenges.

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.
