Summary
2, also known as Hoe Ranch Road, is a privately owned dam located in Arvada, Wyoming, along Goble Draw. Completed in 1972, this earth dam stands at a height of 25 feet and serves multiple purposes including fire protection, stock watering, and small fish pond creation. With a storage capacity of 64 acre-feet, the dam covers a surface area of 6 acres and has a drainage area of 6.3 square miles.
Despite its low hazard potential, Goble No. 2 is currently assessed as being in poor condition, with its last inspection in July 2021 revealing the need for maintenance and repairs. The dam's spillway, which is uncontrolled, has a width of 8 feet, and the outlet gates are also uncontrolled. The risk assessment for this dam is moderate, indicating the need for ongoing monitoring and potential risk management measures to ensure its safety and integrity for the surrounding community and ecosystem.
Located in Congressional District 00, Wyoming, Goble No. 2 is overseen by the Wyoming State Engineer's Office and is subject to state regulation, permitting, inspection, and enforcement. With its strategic location and vital role in providing water resources for various purposes, this dam serves as a crucial infrastructure element in the region's water management system, highlighting the importance of proactive maintenance and risk management practices to ensure its continued functionality and safety in the face of changing climate conditions.

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.
