Summary
Completed in 1992, this Earth-type dam stands at a height of 17 feet and has a normal storage capacity of 57 acre-feet. Situated on the Spring Grouse Creek, this dam plays a crucial role in managing water resources in the region.
With a low hazard potential and fair condition assessment, Grouse Creek Main Dam has been inspected regularly, with the last assessment conducted in October 2017. The dam features an uncontrolled spillway with a width of 5 feet, ensuring the safe release of excess water during periods of high flow. While the risk assessment indicates a moderate level of risk, measures are in place to manage any potential issues that may arise.
Overall, Grouse Creek Main Dam is a key infrastructure component in the water resource management system of the area, providing essential irrigation water for agricultural activities. Its strategic location and design ensure the efficient utilization of water from Spring Grouse Creek, contributing to the sustainable development of the region while maintaining a focus on safety and risk management.

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.
