Summary
20, located in Humboldt, Nevada, is a Federal-owned structure regulated by the Nevada Department of Water Resources. Situated on Thousand Creek, this Earth-type dam serves as a Fish and Wildlife Pond managed by the Fish and Wildlife Service. With a height of 7 feet and a length of 1120 feet, the dam provides storage capacity of 185 acre-feet, with a normal storage level of 26 acre-feet and a surface area of 23.1 acres.
Despite its low hazard potential, the dam is in poor condition and last inspected in July 2015. With a moderate risk assessment rating of 3 out of 5, there are no Emergency Action Plans in place, raising concerns about potential impacts in the event of a failure. The dam's primary purpose of supporting fish and wildlife habitats underscores the importance of addressing its structural deficiencies to ensure the safety of the surrounding ecosystem and communities.
As a vital component of the local water resource infrastructure, Dufurrena Pond Dam No. 20 requires urgent attention to improve its condition and reduce the risk of failure. With the potential for increased discharge and spillway challenges, ongoing inspection and maintenance efforts are essential to safeguard the surrounding area from potential hazards. Climate and water resource enthusiasts will need to monitor developments related to this dam to ensure its long-term sustainability and effectiveness in supporting fish and wildlife conservation efforts in the region.

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.
