Summary
Owned by the Federal government and managed by the USDA Forest Service, this reservoir was completed in 1940 for recreational purposes. With a dam height of 55 feet and a storage capacity of 1372 acre-feet, Big Cedar Creek offers a serene escape for outdoor enthusiasts seeking to enjoy fishing, wildlife viewing, and other recreational activities in a picturesque setting.
Despite its beauty and recreational appeal, Big Cedar Creek poses a high hazard potential due to its uncontrolled spillway type and moderate risk assessment rating. The dam underwent structural modifications in 2020 to enhance its safety and reliability. While its condition assessment is currently not rated, regular inspections are conducted to ensure the dam's integrity and compliance with safety standards. Additionally, emergency action plans are crucial for mitigating potential risks and ensuring the safety of surrounding communities in case of unforeseen events.
For water resource and climate enthusiasts, Big Cedar Creek serves as a valuable location for observing the intersection of nature, infrastructure, and human recreational activities. Its conservation and management by the Forest Service highlight the importance of sustainable water resource utilization and safety measures in maintaining the ecological balance of this scenic reservoir. As a popular destination for outdoor recreation, Big Cedar Creek offers a unique opportunity to appreciate the beauty of nature while raising awareness of the importance of responsible water resource management in the face of changing climate conditions.

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.
