Summary
Built in 1940 for irrigation purposes, this Earth-type dam stands at 16 feet tall and spans 420 feet in length. With a maximum storage capacity of 101 acre-feet and a normal storage capacity of 43 acre-feet, Crystal Beach serves as a vital water resource for the surrounding area.
Despite being classified as having a low hazard potential, Crystal Beach is considered to have a very high risk due to its location and structural characteristics. The dam features a controlled spillway and a single valve outlet gate. While it has not been rated for its condition, the dam undergoes inspections every 5 years to ensure its safety and functionality. Although it has not been modified in recent years, ongoing risk management measures are crucial for maintaining the integrity of this essential water infrastructure.
Owned by the local government and regulated by the Oklahoma Water Resources Board, Crystal Beach is a key component of the water management system in Woodward County. With its strategic location and historical significance, this dam plays a critical role in supporting agriculture and ensuring water availability for the community. As climate change continues to impact water resources, the maintenance and monitoring of structures like Crystal Beach are essential for sustainable water management 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.
