Summary

With a height of 41 feet and a length of 530 feet, this dam boasts a storage capacity of 520 acre-feet and a surface area of 31 acres. Situated on the TR-Stouts Creek, the dam is regulated by the DAM AND RESERVOIR SAFETY PROG and undergoes regular inspections to ensure its safety and structural integrity.

Despite its satisfactory condition assessment, Snow Hollow Lake Dam has a high hazard potential, highlighting the importance of effective risk management measures. The dam features an uncontrolled spillway with a width of 30 feet and a maximum discharge capacity of 1034 cubic feet per second. The surrounding area is at moderate risk (3) in terms of inundation, underscoring the need for emergency preparedness and communication plans to mitigate potential hazards.

Owned and regulated by a private entity, Snow Hollow Lake Dam serves as a recreational haven for water resource and climate enthusiasts. With its scenic location and ample storage capacity, this dam stands as a testament to the balance between human enjoyment and environmental responsibility in managing water resources.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
