Summary
This earth dam stands at a height of 16 feet and has a hydraulic height of 9 feet, providing critical flood risk reduction for the area. With a storage capacity of 114 acre-feet and a drainage area of 15.4 square miles, the dam plays a crucial role in managing water flow and sediment during heavy rain events.
The dam features an uncontrolled spillway and two uncontrolled outlet gates, allowing for the safe release of excess water when needed. Despite being classified as having a high hazard potential, the dam's condition assessment in 2021 rated it as fair. Regular inspections and maintenance efforts help ensure the structure's integrity and effectiveness in protecting the surrounding communities from flooding risks. Climate and water resource enthusiasts will appreciate the strategic design and functionality of the North Spanish Springs Flood Sediment Basin Dam as a key component of the local flood control infrastructure.
Managed by local government authorities and regulated by the Nevada Department of Water Resources, this dam serves as a vital piece of infrastructure in the region's water management system. With a moderate risk assessment and a history of meeting regulatory guidelines, the North Spanish Springs Flood Sediment Basin Dam stands as a testament to effective flood control and debris management practices in the area. Its strategic location along the North Truckee Drain-TR stream ensures that it plays a crucial role in safeguarding the community against potential flooding events.

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.
