Summary
The dam stands at a height of 30 feet, with a hydraulic height of 29 feet and a structural height of 31 feet. It spans a length of 210 feet and has a storage capacity of 165 acre-feet, providing essential water resources for the surrounding area.
Situated on TR-DuBois Creek, the dam also serves purposes such as fire protection, stock, or small fish pond, and recreation. With a drainage area of 600 acres, a surface area of 40 acres, and a maximum discharge of 190 cubic feet per second, Sprague Lake Dam plays a crucial role in managing water resources in the region. Despite being rated as having a low hazard potential and being in moderate risk, the dam's condition is currently not rated, highlighting the importance of ongoing monitoring and maintenance to ensure its safety and efficacy for the local community.
Managed by a private owner, Sprague Lake Dam does not fall under state regulation or inspection. However, its vital role in providing water for wildlife and recreational activities underscores the importance of sustainable water resource management in the face of climate change challenges. For water resource and climate enthusiasts, Sprague Lake Dam serves as a fascinating example of how human-made structures can support and enhance natural ecosystems while adapting to changing environmental conditions.

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.
