Summary
Built in 1956, this earth dam is 24 feet high and stretches 856 feet in length, with a storage capacity of 96 acre-feet. The pond serves as a tributary of the Cheyenne River and is overseen by the Natural Resources Conservation Service for design and construction.
Despite its low hazard potential, Simons Pond plays a crucial role in water management and conservation efforts in the region. With a normal storage capacity of 72 acre-feet and a maximum discharge of 3410 cubic feet per second, the dam helps regulate water flow and protect against potential flooding events. Although the condition assessment is currently listed as "Not Rated," the pond's strategic location and design make it a valuable asset for maintaining water quality and ensuring sustainable resource management for the surrounding community.
As a key infrastructure for water supply and management, Simons Pond underscores the importance of responsible stewardship in the face of climate change and increasing water scarcity. With its state-regulated status and critical role in the local ecosystem, the pond represents a blend of human ingenuity and environmental resilience, serving as a model for sustainable water resource management in the region.

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.
