Summary
This privately owned Earth dam stands at a height of 40 feet and has a storage capacity of 130 acre-feet. Despite its relatively small size, the dam plays a vital role in regulating the flow of an unnamed tributary of Grassy Fork, providing essential water supply and flood control benefits to the region.
With a low hazard potential but poor condition assessment, Tackett Lake Dam faces challenges in maintaining its structural integrity and safety. The dam lacks a spillway and outlet gates, raising concerns about its ability to handle maximum discharge events. Additionally, the last inspection conducted in 2012 revealed the dam's poor condition, highlighting the need for regular maintenance and potential upgrades to ensure its continued functionality and safety for surrounding communities.
As climate change impacts water resources and infrastructure, the risk assessment for Tackett Lake Dam indicates a high level of vulnerability. With no Emergency Action Plan (EAP) in place and outdated inspection data, there is a pressing need for improved risk management measures and emergency preparedness to mitigate potential hazards and protect downstream areas from the consequences of dam failure. Climate enthusiasts and water resource advocates alike should monitor the situation closely and advocate for proactive measures to safeguard Tackett Lake Dam and the surrounding ecosystem.

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.
