Summary
Standing at a height of 15 feet and stretching 1200 feet in length, the dam serves a primary purpose of "Other" with a storage capacity of 550 acre-feet. It features an uncontrolled spillway with a width of 143 feet and two uncontrolled outlet gates.
Despite being last inspected in 2013 with a moderate risk assessment rating, the dam's hazard potential and condition assessment are currently marked as "Not Available" and "Not Rated", respectively. While it is state-regulated and undergoes periodic inspections, the enforcement of regulatory measures is not conducted by the state. The dam's emergency action plan was last revised in 2011, with details on emergency contacts and inundation maps pending updates.
Water resource and climate enthusiasts interested in the Lower Lake Avery Dam can explore its historical significance, engineering design, and environmental impact. The dam's location and features along Kickapoo Creek offer a unique insight into water management in the region, highlighting the importance of monitoring and maintaining infrastructure to ensure public safety and ecosystem health. With its rich history dating back over a century, the dam remains a key structure in the local landscape, warranting continued attention and assessment for future sustainability.

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.
