Summary
This earth dam stands at 29 feet high and spans 568 feet in length, serving as a flood risk reduction structure along the West Fork Big Creek. With a storage capacity of 75.6 acre-feet and a normal storage level of 18.4 acre-feet, the dam helps manage water flow and reduce the risk of flooding in the area.
Despite being classified as low hazard potential, the dam is considered to have a very high risk due to its critical role in flood risk reduction. Additionally, the dam has not been rated for its condition assessment, highlighting the importance of regular inspections and maintenance to ensure its continued functionality. With a controlled spillway and no outlet gates, the dam relies on its structure to manage water levels and protect the surrounding community in Brooklyn.
Managed by the local government, West Fork Big Creek Dam B- 87 is a vital infrastructure for water resource management in the area. Its design by USDA NRCS and purpose for flood risk reduction demonstrate the importance of sustainable water management practices in mitigating the impacts of climate change on water resources. As climate enthusiasts, understanding and supporting the maintenance and operation of such dams is crucial in ensuring the resilience of water infrastructure in the face of changing climate patterns.

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.
