Summary
Standing at a height of 32 feet and with a length of 355 feet, the dam has a storage capacity of 25 acre-feet and serves multiple functions including recreation and water supply. Despite its low hazard potential and moderate risk assessment rating, the dam has not been officially rated for its condition and lacks a formal emergency action plan.
The dam's uncontrolled spillway, with a width of 10 feet, is designed to handle a maximum discharge of 66.35 cubic feet per second. The surrounding area covers 13 acres with a drainage area of 450 acres, making it an important water resource infrastructure in the region. Although the dam has not undergone recent inspections, it remains a crucial component of the local water management system, contributing to flood control and water conservation efforts in the area. Enthusiasts of water resources and climate management will find William Spooner Dam to be an intriguing example of how infrastructure can serve multiple purposes while also posing potential risks that need to be carefully monitored and managed.

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.
