Summary
Standing at a height of 32 feet with a hydraulic height of 27 feet, this earth dam serves the primary purpose of irrigation, providing a storage capacity of 507 acre-feet. Despite its low hazard potential and fair condition assessment, the dam is regulated by the State Engineer's Office with regular inspections, permitting, and enforcement to ensure safety and compliance.
With a spillway width of 50 feet and a controlled slide gate outlet, Artesian Lower has a surface area of 35 acres and a drainage area of 0. The dam's risk assessment is rated as moderate, indicating a need for ongoing risk management measures. Although the dam has no associated structures and a relatively low-risk profile, its strategic location in the Arvada city area underscores the importance of maintaining its integrity for continued irrigation and water resource management in the region.
In conclusion, Artesian Lower plays a crucial role in supporting agricultural activities in the region, highlighting the intersection of water resource management and climate resilience. With its historical significance and ongoing regulatory oversight, this earth dam serves as a testament to the importance of sustainable water infrastructure for local communities. As water enthusiasts and climate advocates, understanding and supporting the maintenance of structures like Artesian Lower is vital for ensuring a secure and reliable water supply in the face of changing environmental conditions.

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.
