Summary

The dam, completed in 1963, stands at 29 feet high and serves primarily for flood risk reduction. With a storage capacity of 233 acre-feet and a drainage area of 4.86 square miles, Deer Creek plays a crucial role in managing water flow and preventing potential flooding in the region.

The dam has a high hazard potential but is currently deemed to be in satisfactory condition as of the last assessment in September 2017. Regular inspections ensure the structure's safety and integrity, with the last inspection conducted in October 2020. Despite its age, Deer Creek continues to effectively mitigate flood risks and safeguard the surrounding community. The dam's emergency action plan is periodically reviewed and updated to meet guidelines, underscoring the commitment to maintaining its functionality in the face of potential emergencies.

Managed by the Natural Resources Conservation Service, Deer Creek exemplifies the importance of proactive water resource management in the face of climate variability. As a key structure in the region's flood risk reduction efforts, the dam stands as a testament to the ongoing commitment to safeguarding communities and ecosystems in the face of evolving environmental challenges.

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.
