Summary
This impressive dam stands at a height of 118 feet and has a hydraulic height of 109 feet, serving primarily for recreational purposes. With a storage capacity of 14,260 acre-feet and a surface area of 325 acres, Alpine Lake Dam provides a picturesque setting for outdoor activities such as fishing, boating, and swimming.
The dam spans a length of 1,279 feet and is situated on Cave Creek, within the St. Louis District. Its high hazard potential is mitigated by regular inspections, with the last assessment reported as satisfactory in March 2012. The surrounding area of Warren County boasts a drainage area of 2,553 acres, ensuring a sufficient water supply for the reservoir. Despite its remote location, Alpine Lake Dam is subject to state regulations and inspections, demonstrating a commitment to safety and environmental stewardship.
Alpine Lake Dam is not only a recreational haven but also a vital component of the local ecosystem, providing habitat for aquatic species and enhancing the natural landscape. Climate and water resource enthusiasts will appreciate the engineering feat of this earth dam, as well as the careful management and monitoring processes in place to ensure its continued safety and functionality. With its tranquil waters and scenic surroundings, Alpine Lake Dam is a testament to the harmonious coexistence of human infrastructure and natural beauty in the heart of Missouri's wilderness.

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.
