Summary
With a height of 19 feet and a hydraulic height of 14 feet, this dam on Nine Mile Creek has a normal storage capacity of 91 acre-feet and a maximum storage of 194 acre-feet. The dam stretches 335 feet in length and covers a surface area of 17 acres.
Despite its low hazard potential and fair condition assessment, Hague Paxton is subject to state regulation and inspection, with the Wyoming State Engineer's Office overseeing its permitting, enforcement, and regulatory requirements. The dam's uncontrolled spillway, measuring 130 feet in width, serves as a safety feature for potential overflow events. The last inspection in April 2017 deemed the dam to be in satisfactory condition, highlighting its moderate risk level and the need for ongoing risk management measures.
Located in a remote area 64 miles from Arvada, Hague Paxton serves as a critical infrastructure for local fire protection and agricultural activities. With its earth dam structure and stone core, the dam plays a vital role in water resource management and climate resilience in the region. As water resource and climate enthusiasts, it is important to monitor and support the maintenance of dams like Hague Paxton to ensure their continued safety and functionality for the community.

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.
