Summary
Built in 1909, this earth dam has a height of 19 feet and a length of 480 feet, providing a storage capacity of 120 acre-feet. Situated on the S. Santa Clara Creek-Tr river, this dam has a low hazard potential and has not been rated for its condition assessment.
Despite its age, Arnold Flood Water remains a crucial asset for water management in the region, with a normal storage capacity of 96 acre-feet and a maximum discharge of 130 cubic feet per second. This privately owned structure is regulated by the Colorado Division of Water Resources, ensuring its compliance with state permitting, inspection, and enforcement protocols. While the dam has not been modified in recent years, it continues to play a significant role in safeguarding the surrounding area from potential flooding events.
With a risk assessment rating of 'High (2)', the Arnold Flood Water structure underscores the importance of ongoing risk management measures to mitigate any potential hazards. Although its last inspection dates back to 1992, the dam's emergency action plan status, inundation maps, and risk management strategies remain unspecified. As climate change impacts water resources, the maintenance and monitoring of structures like Arnold Flood Water become increasingly crucial to ensure the safety and sustainability of local communities and ecosystems.

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.
