Summary
Completed in 1997, this Earth-type dam stands at a height of 27 feet and spans 301 feet in length. Its primary purpose is debris control, with additional functions including serving as a fish and wildlife pond and a recreation area. The dam is situated on Hewett Run and has a normal storage capacity of 61 acre-feet, covering a surface area of 4 acres and draining a 2-acre watershed.
Managed by the Forest Service, Avis Dam is classified as having low hazard potential and moderate risk, with a designated inspection frequency of 10 years. The uncontrolled spillway of the dam has a width of 16 feet. While the condition assessment is currently not rated, the risk assessment indicates a moderate level of risk. The dam does not have an Emergency Action Plan (EAP) prepared at this time, and no inundation maps have been created for the area. Despite these factors, Avis Dam remains a key structure for debris control and wildlife habitat in the region, attracting water resource and climate enthusiasts alike.

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.
