Summary
Built in 1976, this earth dam stands at a hydraulic height of 20.9 feet and a structural height of 26.9 feet, with a total length of 410 feet. With a normal storage capacity of 63 acre-feet and a maximum storage of 99 acre-feet, Crystal serves as a critical component in managing water resources in the area, particularly for the Spring Creek watershed.
Despite its satisfactory condition assessment, Crystal poses a high hazard potential due to its location and design. The dam's spillway is uncontrolled, adding to the risk of potential flooding and necessitating regular inspections by the state regulatory agency. While the dam's emergency action plan status and risk assessment level are not currently specified, its role in water resource management underscores the importance of maintaining its structural integrity and readiness for any potential emergencies. Enthusiasts of water resources and climate will find the details of Crystal's design, operation, and regulatory oversight intriguing as they highlight the intersection of human infrastructure with natural ecosystems.

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.
