Summary
Built in 1977, this earth dam stands at a height of 31 feet and has a maximum storage capacity of 53 acre-feet. Its primary purpose is to prevent erosion and stabilize the surrounding area, with a spillway width of 40 feet to control water discharge during heavy rainfall events.
Situated on the Thompson River, this dam plays a crucial role in managing the water resources of the region, with a drainage area of 288 acres and a surface area of 1 acre. Despite its low hazard potential, the dam is deemed to have a moderate risk level, with no specific risk management measures outlined. The site's condition assessment is currently not rated, suggesting the need for further evaluation to ensure its continued safety and effectiveness in the face of climate change and evolving water resource management practices.
Overall, the Springer-Sharon Site Ca-33-H-55-4 is a key infrastructure component in the local water management system, providing important grade stabilization benefits and contributing to the overall resilience of the region. With its strategic location and design features, this dam serves as a critical asset in safeguarding the surrounding environment and communities against potential flood risks and water resource challenges.

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.
