Summary
2 is a privately owned irrigation dam located in Arvada, Wyoming, along Clear Creek. Completed in 1972, this earth dam stands at a height of 55 feet and has a hydraulic height of 49 feet, providing vital irrigation water storage for the surrounding area. With a maximum storage capacity of 594 acre-feet and a normal storage level of 415 acre-feet, the dam plays a crucial role in supporting agricultural activities in the region.
Despite its importance, the condition assessment of Stevens No. 2 reveals a poor state, with a hazard potential rated as low. The last inspection in 2017 highlighted the need for maintenance and improvements to ensure the dam's structural integrity and overall safety. With an outdated emergency action plan and a moderate risk level assigned, there is a pressing need for updated risk assessment, management measures, and emergency preparedness to mitigate potential hazards and safeguard the dam's functionality in the face of changing climate conditions.
As water resource and climate enthusiasts, it is essential to monitor and support initiatives aimed at enhancing the resilience and sustainability of infrastructure like Stevens No. 2. By advocating for regular inspections, maintenance, and emergency preparedness measures, stakeholders can contribute to the preservation of this critical water resource and ensure its continued benefit to the local community and environment.

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.
