Summary
2 is a private earth dam located in Campbell, Wyoming, specifically in the city of Arvada along the Upper Draw river. Completed in 1966, this dam serves multiple purposes including fire protection, stock maintenance, and small fish pond support. With a structural height of 33 feet and a hydraulic height of 22 feet, Boyken No. 2 has a storage capacity of 57 acre-feet and a surface area of 4 acres.
Despite its age, Boyken No. 2 is considered to have a low hazard potential and is in fair condition as of the last assessment in 2017. The dam features an uncontrolled spillway with a width of 100 feet, ensuring proper water flow management in case of excess storage. The dam is regularly inspected every 5 years to maintain its structural integrity and ensure safety for the surrounding area.
Overall, Boyken No. 2 provides vital water resource management functions in the region, demonstrating the importance of proper dam maintenance and inspection protocols to mitigate potential risks and ensure continued operational efficiency for fire protection, stock maintenance, and small fish pond support.

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.
