Summary
The dam stands at a height of 11 feet and has a hydraulic height of 8 feet, with a length of 3040 feet and a storage capacity of 327 acre-feet. Despite its low hazard potential, the dam is currently assessed as being in poor condition, with the last inspection conducted in July 2019.
Managed by the Nevada Division of Water Resources, Dewey Parker Dam No 2 regulates the Buffalo Slough-OS stream and serves multiple purposes including fire protection, stock watering, and maintaining small fish ponds. The dam's spillway type is uncontrolled, with a width of 10 feet, and features a slide gate outlet. While the dam has not undergone any significant modifications in recent years, it is subject to regular state inspections, enforcement, and permitting to ensure its safety and compliance with regulatory standards.
For water resource and climate enthusiasts, Dewey Parker Dam No 2 offers a fascinating glimpse into the infrastructure supporting agricultural activities in the region. Despite its age and condition assessment, the dam continues to play a crucial role in sustaining water resources for irrigation and other purposes in Washoe County. With its historical significance and ongoing regulatory oversight, the dam represents a valuable asset in the management of water resources and the preservation of the surrounding ecosystem.

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.
