Summary
With a structural height of 26 feet and a length of 715 feet, this dam holds a maximum storage capacity of 110 acre-feet and a normal storage of 55.43 acre-feet. Situated on Twin Spring Creek, the dam serves as a crucial water resource in the region, covering a surface area of 8 acres and draining an area of 1.68 square miles.
Despite its fair condition assessment and low hazard potential, the Twin Springs Dam poses a high risk, as indicated by a risk assessment rating of 2. While it lacks a spillway, outlet gates, and locks, the dam has a maximum discharge capacity of 598 cubic feet per second. The dam is owned, funded, designed, constructed, regulated, inspected, and operated by the Bureau of Land Management, showcasing the federal agency's comprehensive involvement in its management and maintenance. Twin Springs Dam stands as a testament to sustainable water management practices in the face of climate change challenges.
Enthusiasts of water resources and climate sustainability can appreciate the Twin Springs Dam for its vital role in providing water supply to the region while highlighting the importance of responsible dam construction and maintenance. With its strategic location and significant storage capacity, the dam serves as a critical infrastructure asset in managing water resources and mitigating potential risks associated with high-hazard events. As climate change impacts become more pronounced, the Twin Springs Dam exemplifies the need for resilient infrastructure to ensure water security for communities and ecosystems in Oregon.

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.
