Summary
This earth dam, situated on Deans Branch, serves the primary purpose of recreation and offers a storage capacity of 80 acre-feet. While it is privately owned and not regulated by the state, the dam is considered to have a significant hazard potential.
Despite being constructed over seven decades ago, Arnoname 4 Dougherty's Dam continues to provide recreational opportunities for locals and visitors alike in the city of Ward. Its serene location and picturesque surroundings make it a popular spot for fishing, boating, and other leisure activities. With a focus on maintaining safety and ensuring proper risk management measures, the dam remains an important part of the community's water resource infrastructure.
While the dam's condition assessment is currently listed as "Not Rated," efforts are being made to update emergency action plans and ensure that the structure meets safety guidelines. As climate change continues to impact water resources and infrastructure, the importance of maintaining and monitoring dams like Arnoname 4 Dougherty's Dam becomes increasingly crucial. By staying proactive and prepared, this dam can continue to provide both recreational enjoyment and essential water storage for years to come.

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.
