Summary
Completed in 1977, this dam serves the primary purpose of grade stabilization and stands at a height of 30 feet with a length of 270 feet. With a storage capacity of 20 acre-feet and a drainage area of 130 acres, this dam plays a crucial role in managing water resources and controlling the flow of the river.
Despite being classified as a low hazard potential structure with a moderate risk assessment, the Springer-Sharon Site Ca-33-H-55-2 has not been rated for its condition assessment. This dam features an uncontrolled spillway type with a width of 10 feet and no outlet gates. While there are no associated locks, the dam serves as a critical infrastructure for the local government of Harrison County, Missouri. Water resource and climate enthusiasts will find the Springer-Sharon Site Ca-33-H-55-2 to be an intriguing example of earth dam engineering and water management in the region.
As part of the Rock Island District and with Congressman Sam Graves representing the area, the Springer-Sharon Site Ca-33-H-55-2 showcases the importance of local government ownership in maintaining and regulating essential water structures. With a surface area of 15 acres and a maximum discharge capacity of 80 cubic feet per second, this dam is a key component in the region's water management system. While it has not been inspected recently, the dam's emergency action plan and risk management measures play a crucial role in ensuring the safety and resilience of the surrounding community in the face of potential hazards.

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.
