Summary
Fork Bridger Creek. Managed by the Bureau of Land Management, this federal-owned structure stands at a height of 46 feet and has a hydraulic height of 35 feet, with a storage capacity of 147.5 acre-feet. Despite its significant hazard potential and poor condition assessment, the dam plays a crucial role in protecting the surrounding area from potential flooding events.
The dam's structural integrity was last modified in 2006, indicating ongoing efforts to ensure its functionality. With a spillway type classified as uncontrolled and a maximum discharge capacity of 8910 cubic feet per second, the Depression Detention Dam is equipped to handle high water levels and mitigate flood risks effectively. Although its condition is assessed as poor, the dam's risk management measures and moderate risk assessment suggest that it continues to serve its primary purpose of flood risk reduction, highlighting the importance of maintaining and monitoring this critical water resource infrastructure for the community's safety and well-being.

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.
