Summary
With a height of 34 feet and a length of 410 feet, this dam has a storage capacity of 22 acre-feet and serves as a vital resource for the local community. Despite its critical role in water management, Hopper Gss lacks a spillway and has a high hazard potential, indicating the need for continued monitoring and maintenance.
This dam, situated along the TR-Cottonwood Creek, is under state permitting and inspection, but not subject to state regulation or enforcement. Although it is not rated for its current condition, the risk assessment for Hopper Gss is classified as high, emphasizing the importance of implementing risk management measures to ensure its structural integrity and safety. With its primary purpose being fire protection and stock maintenance, Hopper Gss also offers recreational opportunities for the community to enjoy.
In the event of an emergency, the lack of an Emergency Action Plan (EAP) and updated contact information raises concerns about the dam's preparedness for unforeseen events. As water resource and climate enthusiasts, it is essential to advocate for the development of a comprehensive EAP, regular inspections, and maintenance to safeguard Hopper Gss and other critical infrastructure in the region. By raising awareness about the importance of proactive risk management, we can contribute to the long-term sustainability of water resources and resilience to climate impacts in the area.

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.
