Summary

Built in 1990 by the USDA NRCS, this dam serves the primary purpose of flood risk reduction along the TR-East Locust Creek. With a height of 28 feet and a length of 420 feet, the dam has a storage capacity of 103 acre-feet and covers a surface area of 6 acres.

Despite being classified as low-hazard potential, the dam is considered to have a moderate risk level (3) due to its location and design. The spillway, with a width of 20 feet, is uncontrolled, allowing for a maximum discharge of 154 cubic feet per second. The dam has not been inspected since 1991, and its condition assessment is marked as "Not Rated," highlighting the need for further evaluation and maintenance.

Water resource and climate enthusiasts will find East Locust Creek Watershed Dam E- 64 an important structure in the region's flood risk management efforts. With its strategic location and significant storage capacity, the dam plays a vital role in protecting the surrounding areas from potential inundation. However, continued monitoring and assessment of the dam's condition are necessary to ensure its long-term effectiveness and safety for the community.

Condition Assessment

Satisfactory
No 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

High
Dams 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.
