Summary
This Earth-type dam stands at a height of 10 feet with a hydraulic height of 7 feet, serving as a vital component in managing the flow of the Carson River-OS. With a storage capacity of 2000 acre-feet and a normal storage level of 900 acre-feet, this dam plays a crucial role in sustaining agricultural activities in the region.
Despite being classified as having a low hazard potential, Ollie's Pond Dam is considered to have a very high risk assessment, signaling the importance of regular inspections and maintenance. The last inspection took place in April 2013, with an inspection frequency of 5 years. The dam features a controlled spillway type with a width of 5 feet, ensuring efficient water flow management during periods of high discharge. Although the condition assessment is currently labeled as "Not Rated," the risk management measures for this dam remain unspecified.
For water resource and climate enthusiasts, Ollie's Pond Dam represents a key infrastructure supporting irrigation and recreation activities in the area. With its strategic location along the Carson River-OS and a storage capacity of 2000 acre-feet, this dam serves as a critical water management system for the region. While categorized with a low hazard potential, the high risk assessment underscores the importance of ongoing monitoring and upkeep to ensure the safety and functionality of this essential water resource structure.

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.
