Summary
Completed in 1960, this dam stands at 46 feet high with a hydraulic height of 42 feet and a length of 1020 feet, providing a maximum storage capacity of 563 acre-feet and a normal storage of 200 acre-feet. The dam's spillway type is controlled, with a spillway width of 1 foot, and it features a valve outlet gate for water release.
Despite being categorized as having a low hazard potential, the risk assessment for SCS-Rush Creek Site-006 indicates a very high risk level (1), suggesting potential vulnerabilities that may require attention. The dam's condition assessment is currently not rated, with the last inspection being conducted in 1980. With the dam falling under state jurisdiction and permitting, inspection, and enforcement processes, it is essential to prioritize regular evaluations and maintenance to ensure its structural integrity and effectiveness in flood risk management. Water resource and climate enthusiasts interested in the intersection of infrastructure, environmental management, and risk mitigation will find SCS-Rush Creek Site-006 a compelling case study for understanding the complexities of dam regulation and maintenance in safeguarding communities from flooding events.

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.
