Summary

Built in 1955 by the USDA NRCS, this dam stands at a height of 40 feet and has a hydraulic height of 35 feet. With a normal storage capacity of 117 acre-feet and a maximum storage of 167 acre-feet, this dam serves as a crucial structure in managing water flow in the area.

The dam's spillway type is controlled, with a spillway width of 1 foot, and it is equipped with a valve for water release. Despite its age, this dam has a hazard potential rated as low, with a condition assessment that is currently not rated. While the last inspection was conducted in 1980 with a frequency of every 5 years, the risk assessment for this dam is categorized as very high (1), highlighting the importance of continued monitoring and maintenance to ensure its safety and effectiveness in flood control. Water resource and climate enthusiasts will find SCS-Barnitz Creek Site-036 to be a fascinating example of infrastructure designed to mitigate flood risks in a state-regulated environment.

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.
