Summary
Built in 1880, this earth dam stands at 17 feet high and has a storage capacity of 5 acre-feet. With a surface area of 0.6 acres and a drainage area of 0.28 square miles, this reservoir plays a crucial role in meeting the water needs of the area.
Despite its historical significance and vital function, Lake Casper is currently facing challenges in terms of its condition assessment, rated as poor, and its hazard potential categorized as significant. The last inspection in 2014 revealed these issues, highlighting the importance of ongoing maintenance and upgrades to ensure the safety and efficiency of the dam. For water resource and climate enthusiasts, Lake Casper serves as a valuable case study in the management and preservation of essential water infrastructure in the face of changing environmental conditions and evolving regulatory standards.
With its multi-arch core type design and soil foundation, Lake Casper stands as a testament to the engineering ingenuity of its time. As efforts continue to address its poor condition and significant hazard potential, the future of this water supply reservoir remains a topic of interest for those passionate about sustainable water resource management and climate resilience. As the community works towards enhancing the safety and functionality of Lake Casper, it serves as a reminder of the critical role that water infrastructure plays in supporting our daily lives and the need for proactive measures to ensure its reliability for generations to come.

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.
