Summary
Completed in 1990, this Earth-type dam stands at a height of 21 feet and has a storage capacity of 160 acre-feet. Situated on the Humboldt River-OS, the dam serves multiple purposes, including flood control and water storage for the surrounding community.
With a low hazard potential and a moderate risk assessment rating, Carlin Ww East Rib Dam is regulated by the Nevada Department of Water Resources and undergoes regular inspections to ensure its structural integrity. The dam features an uncontrolled spillway and is equipped with a slide gate for outlet control. While its condition assessment is currently not rated, the dam is deemed to meet safety guidelines and is equipped to handle potential emergencies.
Managed by the local government and overseen by the Nevada DWR, Carlin Ww East Rib Dam stands as a vital infrastructure for water management in Elko County. With its strategic location and design, this dam continues to play a critical role in maintaining water supply, mitigating flood risks, and supporting agricultural activities in the region. Climate and water resource enthusiasts will find this dam a fascinating example of infrastructure designed to meet the challenges of water management in a changing climate.

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.
