Summary
The dam, primarily made of masonry, stands at a height of 28 feet and has a length of 100 feet. It has a storage capacity of 3860 acre-feet, with a normal storage level of 2000 acre-feet.
The dam's spillway type is uncontrolled, with a width of 30 feet, and it features two slide (sluice gate) outlet gates. The dam has undergone modifications in 1979 for both hydraulic and structural improvements. Despite being assessed as in fair condition as of June 2019, it has been designated as having a significant hazard potential and a moderate risk level. The dam is regulated and inspected by the Nevada Department of Water Resources, ensuring its safety and compliance with state regulations.
Water resource and climate enthusiasts will find Knott Creek Reservoir Dam a fascinating structure due to its multi-purpose usage, historical modifications, and the ongoing efforts to manage its risk potential. Its strategic location in Humboldt, Nevada, adds to its significance as a vital infrastructure supporting irrigation, fire protection, and recreational activities in the region. With its intricate design and state-regulated status, the dam serves as a critical component of water resource management in the area, highlighting the intersection of human engineering and environmental sustainability.

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.
