Summary
Completed in 1993 by the USDA NRCS, this earth dam stands at a height of 33.3 feet and has a hydraulic height of 31 feet, with a structural height of 36 feet. The dam spans a length of 490 feet and has a storage capacity of 128 acre-feet, with a normal storage level of 43 acre-feet.
Situated on TR-Tanyard Creek, the dam serves the primary purpose of flood risk reduction and is classified as having a low hazard potential. Although not currently regulated by the state, Upper Locust Creek L-109 plays a crucial role in protecting the surrounding area from potential flooding events. With a drainage area of 32 square miles and a maximum discharge of 212 cubic feet per second, the dam remains a critical infrastructure for water resource management in the region.
Despite being last inspected in 1998 and not currently rated for its condition, Upper Locust Creek L-109 continues to be monitored for any potential risks. With emergency action plans yet to be prepared and a moderate risk assessment rating of 3, there is a need for ongoing evaluation and management of this essential structure to ensure the safety and resilience of the community it serves.

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.
