Summary
Built in 1920, this structure stands at a height of 14 feet and has a normal storage capacity of 336 acre-feet. Situated on Fillmore Creek, Seaverson serves as a vital resource for the surrounding area, providing water for various uses including recreation.
Despite its low hazard potential, Seaverson is currently in poor condition as of the last inspection in October 2018. The dam's emergency action plan and risk management measures are not fully updated or in place, indicating a need for improvement in safety protocols. With a moderate risk assessment score of 3, there is a call to action for enhancing the dam's structural integrity and preparedness for potential emergencies.
Water resource and climate enthusiasts should keep a close eye on Seaverson's maintenance and risk mitigation efforts to ensure the safety and sustainability of this important water storage facility. As climate change continues to impact water resources, it is crucial to prioritize the upkeep and modernization of dams like Seaverson to adapt to evolving environmental conditions and safeguard local communities.

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.
