Summary
This earth dam stands at 24 feet high with a hydraulic height matching at 24 feet, and a structural height of 25 feet. With a maximum storage capacity of 106 acre-feet, this dam serves the dual purposes of providing a habitat for fish and wildlife while also reducing flood risks in the area.
The dam spans a length of 574 feet and covers a surface area of 3 acres, serving a drainage area of 150 acres. With a low hazard potential and a moderate risk assessment rating, Troublesome Creek Watershed Dam T- 85 is equipped with an uncontrolled spillway that is 24 feet wide. Although last inspected in 1999, this dam has not been rated for its current condition, but it remains operational with no reported issues. Despite not being state regulated, this dam plays a crucial role in managing water resources and mitigating flood risks in the region.
Owned by the local government, Troublesome Creek Watershed Dam T- 85 is a vital infrastructure designed by the Natural Resources Conservation Service to protect the surrounding area from potential flooding events. With its modest size and storage capacity, this dam is an essential component of the flood risk reduction strategy in the region. While it may not be regularly inspected or regulated by the state, its presence and functionality contribute significantly to the water resource management efforts in the Troublesome Creek watershed.

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.
