Summary
This local government-owned dam serves multiple purposes, including flood risk reduction, with a primary dam type of Earth and a height of 18 feet. Completed in 1968, it has a storage capacity of 74 acre-feet and covers a surface area of 6 acres, draining an area of 0.4 square miles.
With a low hazard potential and a satisfactory condition assessment as of June 2016, Spring Creek 4-3 plays a crucial role in managing water resources in the region. The dam has a maximum discharge of 291 cubic feet per second and is equipped with inspection and enforcement measures to ensure its structural integrity and safety. While the dam does not fall under the jurisdiction of the US Army Corps of Engineers, its operation and maintenance are overseen by the Natural Resources Conservation Service.
As a key component in the management of the TR-SPRING CREEK watershed, Spring Creek 4-3 provides essential flood protection and water storage capabilities for the local community. Its strategic location and design by USDA NRCS reflect a commitment to sustainable water resource management and climate resilience in the face of changing environmental conditions. With ongoing inspection and regulatory oversight, this dam continues to contribute to the overall water security and safety of the region.

Dam Data Reference
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.
