Summary
Built in 1995 by the Bureau of Land Management, this dam stands at a height of 46 feet and has a hydraulic height of 35 feet. With a storage capacity of 1209.9 acre-feet and a normal storage of 553.16 acre-feet, Anita Dam plays a crucial role in water resource management in the area.
Despite being structurally modified in 2005, Anita Dam is classified as having a high hazard potential with a fair condition assessment. The dam spans 1200 feet in length and has a surface area of 66.7 acres, serving as a vital infrastructure for water storage and management. The dam is under the jurisdiction of the Bureau of Land Management and is not regulated by the state, showcasing the federal agency's involvement and responsibility in its operations and maintenance.
With a maximum discharge capacity of 23,245 cubic feet per second and an uncontrolled spillway type, Anita Dam presents both opportunities and challenges for water resource and climate enthusiasts. As a significant part of the local water infrastructure, the dam's management, maintenance, and risk assessment remain crucial for ensuring the safety and sustainability of water resources in the region.

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.
