Summary
The primary purpose of this earth dam is flood risk reduction along the TR-LONG BRANCH river or stream. With a height of 23.4 feet and a hydraulic height of 21 feet, East Yellow Creek L- 25 has a storage capacity of 67.9 acre-feet and a drainage area of 384 square miles.
This dam has a low hazard potential and is currently in a not rated condition assessment. It features an uncontrolled spillway with a width of 20 feet and outlet gates that are uncontrolled as well. Despite being unregulated by the state, East Yellow Creek L- 25 serves as a crucial infrastructure for managing flood risks in the area. With a moderate risk assessment rating of 3, the dam is an essential component in the region's water resource and climate management efforts.
Water resource and climate enthusiasts will appreciate the role of East Yellow Creek L- 25 in mitigating flood risks and protecting the local community from potential hazards. As part of the flood risk reduction strategy, this dam provides valuable storage capacity and drainage support for the surrounding area. Its design by USDA NRCS and construction in 2006 demonstrate a commitment to sustainable water management practices. Despite its low hazard potential, ongoing monitoring and maintenance are essential to ensure the continued effectiveness of East Yellow Creek L- 25 in safeguarding the region from flood events.

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.
