Summary
This earth dam stands at a height of 23 feet and serves the primary purpose of flood risk reduction along the TR-ELK CREEK. With a maximum storage capacity of 59 acre-feet and a normal storage of 28 acre-feet, this dam plays a crucial role in managing water resources in the region.
The dam features a controlled spillway with a width of 1 foot and an outlet gate consisting of a single valve. Despite being rated as having a low hazard potential, the risk assessment categorizes SCS-Upper Elk Creek Site-33 as having a very high risk level (1). Despite not being assessed for its condition, this dam is subject to regular inspections every 5 years to ensure its structural integrity and functionality in mitigating flood risks.
As water resource and climate enthusiasts, understanding the design and functionality of dams like SCS-Upper Elk Creek Site-33 is crucial for managing water resources and addressing the impacts of climate change. By highlighting the key features and purpose of this dam, we can better appreciate the importance of effective infrastructure in protecting communities from the devastating effects of flooding and ensuring sustainable water management practices in the region.

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.
