Summary
Built in 1956, this earth dam stands at 32 feet high and serves multiple purposes, including fire protection, stock watering, and small fish pond management. With a storage capacity of 68 acre-feet and a surface area of 5 acres, Applegate primarily caters to the needs of the local community while also contributing to the ecological balance of the area.
Despite its low hazard potential and fair condition assessment, Applegate is subject to state regulation and inspection, ensuring its safety and compliance with relevant standards. The dam's uncontrolled spillway, measuring 40 feet in width, allows for the controlled release of excess water during periods of heavy rainfall or flooding. As part of its risk management measures, Applegate undergoes regular inspections every five years to assess its structural integrity and potential hazards, with the last inspection conducted in April 2018.
Situated in the Congressional District 00 of Wyoming and overseen by the SEO regulatory agency, Applegate stands as a vital water resource for the region, providing essential services for both humans and wildlife. With its strategic location and multi-purpose functionality, Applegate serves as a key component in the local water infrastructure, highlighting the intersection of water resource management and climate resilience in the area.

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.
