Summary
This private-owned dam, standing at a height of 36 feet and stretching 610 feet in length, holds a maximum storage capacity of 290 acre-feet with a normal storage of 180 acre-feet. Situated on the TR-DRY CREEK, this earth dam with a buttress core type plays a vital role in water management and conservation efforts in the area.
Despite its significant role in water supply, Stillwagon Lake Dam has not been rated for its condition assessment, and its hazard potential is currently labeled as "Not Available." The dam lacks a spillway and is not regulated by the state, posing a high risk level of 2. With no recent inspection data available, there is limited information on emergency preparedness measures and risk management strategies in place for the dam. As a crucial infrastructure for water resource management, further assessment and monitoring of the dam's condition and safety protocols are essential to ensure its long-term functionality and to mitigate potential risks.
In the absence of state regulation and inspection data, the condition of Stillwagon Lake Dam remains uncertain, raising concerns for its structural integrity and emergency preparedness. As water resource and climate enthusiasts, it is imperative to advocate for comprehensive risk assessments, regular inspections, and the implementation of effective emergency action plans to safeguard the dam and the surrounding area from potential hazards. Collaboration between private owners, state agencies, and local stakeholders is crucial to ensure the sustainable management of this vital water supply infrastructure in the face of changing climatic conditions and increasing water demands.

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.
