Summary
Built in 1992 by the USDA NRCS, this earth-type dam stands at a height of 24.8 feet and has a storage capacity of 195 acre-feet. With a primary purpose of flood risk reduction, it also serves as a habitat for fish and wildlife.
The dam, with a low hazard potential and a moderate risk assessment, has not been inspected since September 1999. Despite being unregulated by the state, it plays a crucial role in ensuring the safety and protection of the surrounding area in times of heavy rainfall and potential flooding. With an uncontrolled spillway and no outlet gates, the dam's condition assessment remains unrated, highlighting the need for regular maintenance and inspection to uphold its functionality.
While Troublesome Creek Watershed Dam T-66 may not pose an immediate threat, it is essential to prioritize its upkeep and monitoring to prevent any potential risks in the future. As a key structure in the region's flood risk reduction efforts, the dam's significance cannot be understated for both the community and the environment it serves.

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.
