Summary
This earth dam, designed by the USDA NRCS, stands at a height of 23 feet and has a hydraulic height of 22 feet. With a storage capacity of 115 acre-feet and a drainage area of 145 square miles, this dam plays a crucial role in managing water flow and minimizing flood risks in the area.
Despite being classified as having a low hazard potential and a moderate risk assessment, Troublesome Creek Watershed Dam T-87 has not been rated for its condition assessment. The dam, with a spillway width of 30 feet and uncontrolled spillway type, poses a moderate risk but has not been inspected since 1998. The dam's location on Troublesome Creek, its stone core type, and soil foundation make it an essential structure for flood risk reduction in the region, highlighting the importance of regular inspections and maintenance to ensure its continued effectiveness in managing water resources and climate challenges.
As a critical infrastructure owned by the local government, Troublesome Creek Watershed Dam T-87 serves multiple purposes, including fish and wildlife pond management in addition to flood risk reduction. With no state jurisdiction or permitting requirements, this dam relies on the USDA NRCS for design and operation, emphasizing the collaborative effort needed to safeguard water resources and mitigate the impacts of climate change in the region.

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.
