Summary
Built in 1956, this earth dam stands at 21 feet high and has a storage capacity of 145 acre-feet, primarily used for fire protection, stock, and small fish pond purposes. Despite its low hazard potential, the dam is in poor condition as of its last inspection in June 2017, with a moderate risk assessment rating of 3.
The dam's structural components consist of stone core types and soil foundations, with an uncontrolled spillway width of 60 feet. Its emergency action plan status, risk management measures, and inundation maps prepared are currently unknown. While Fowler has not undergone any modifications in recent years, it is subject to state regulation, permitting, inspection, and enforcement, indicating a level of oversight and maintenance to ensure public safety and water resource sustainability in the region.
For water resource and climate enthusiasts, Fowler serves as a notable feature within the water infrastructure of Johnson County, Wyoming. With its historical significance dating back to the mid-20th century and its utilization for multiple purposes, including fire protection and livestock management, Fowler's condition assessment and risk potential highlight the importance of ongoing monitoring and maintenance efforts to safeguard its functionality and mitigate potential hazards in the future.

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.
