Summary
Built in 1997 by the USDA NRCS, this dam stands at a height of 31 feet and has a length of 481 feet. It serves multiple purposes, with a primary purpose classified as 'Other', and has a storage capacity of 215 acre-feet. The dam is regulated and inspected by the OWRB, ensuring its safety and compliance with state standards.
With a drainage area of 1780 acres and a maximum discharge of 1739 cubic feet per second, SCS-Schaefer 1 plays a crucial role in managing water resources in the region. Its controlled spillway and low hazard potential make it a reliable structure for flood control and water storage. Despite being rated as 'Not Rated' in terms of condition assessment, the dam's risk assessment indicates a very high risk level, emphasizing the importance of continued monitoring and maintenance to ensure its long-term functionality.
Even though the last inspection dates back to 2011, with an inspection frequency of 5 years, the dam remains a key feature in the local water infrastructure. As climate change intensifies, structures like SCS-Schaefer 1 become even more essential for mitigating the impacts of extreme weather events and ensuring water security for the community. With its strategic location and design, this dam stands as a testament to the importance of sustainable water management in the face of a changing climate.

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.
