Summary
Constructed in 2007, this Earth-type dam stands at a height of 38 feet with a hydraulic height of 33 feet and a length of 445 feet. With a maximum storage capacity of 36 acre-feet and a normal storage of 28 acre-feet, Fiik covers a surface area of 2.1 acres and has a drainage area of 0.01 square miles.
The dam on Fiik Draw features a valve outlet gate and an uncontrolled spillway with a width of 30 feet, designed to handle a maximum discharge of 555 cubic feet per second. Despite its low hazard potential, Fiik is assessed to be in fair condition as of the last inspection in April 2018. With a moderate risk level, the structure is subject to periodic inspections every five years to ensure its continued safety and functionality. For enthusiasts interested in water resource management and climate impact, Fiik presents an intriguing case study of a multi-purpose dam designed to serve both human and ecological needs in a sensitive ecosystem.
Managed by the federal government and regulated by the State of Wyoming, Fiik exemplifies the collaborative effort required to balance water resource utilization with environmental conservation. With its strategic location along a local road in Congressional District 00, Wyoming, Fiik contributes to the region's water supply, fire protection, and wildlife habitat. As climate change continues to impact water availability and quality, structures like Fiik play a crucial role in sustainable water management practices, highlighting the importance of proper maintenance, risk assessment, and emergency preparedness for resilient water infrastructure in the face of evolving climate challenges.

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.
