Summary
Built in 1959 by the Bureau of Land Management, this gravity dam stands at a structural height of 25 feet with a hydraulic height of 21 feet. It has a storage capacity of 2400.9 acre-feet and covers a surface area of 257.7 acres, providing essential protection against flooding and sediment buildup in the region.
Despite its low hazard potential, Iverson Detention Dam has been rated as having poor condition assessment, highlighting the need for maintenance and potential upgrades. The dam's uncontrolled spillway and moderate risk assessment require regular inspections every 5 years to ensure its structural integrity. With a historical maximum discharge of 2850 cubic feet per second, the dam plays a crucial role in managing water flow and safeguarding the surrounding area from potential risks associated with extreme weather events.
As a federally owned and operated structure, Iverson Detention Dam is a key component of the Bureau of Land Management's efforts to regulate and maintain water resources in the region. With its strategic location and vital role in flood control, this gravity dam stands as a testament to the importance of sustainable water management practices in mitigating the impact of climate change on vulnerable communities.

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.
