Summary
Constructed in 1969 by the USDA NRCS, this earth dam has a height of 41 feet and a length of 600 feet, providing a storage capacity of 660 acre-feet to regulate the flow of the TRIB-PATTEE CREEK. With a drainage area of 5 square miles, the dam plays a vital role in flood control and water supply management in the region.
Although the dam has a low hazard potential, its condition assessment remains ungraded as of now. The last inspection conducted on May 7, 1980, revealed no significant issues, indicating the sound structural integrity of the dam. Despite not being under the jurisdiction of the USACE, the dam is regulated by the state agency DANR, ensuring its compliance with state permitting, inspection, and enforcement protocols. With a primary purpose not specified, the Pattee Creek Watershed P-2 dam continues to serve as a critical infrastructure for water resource management in the area.
In the realm of water resource and climate enthusiasts, the Pattee Creek Watershed P-2 dam presents a fascinating case study in sustainable infrastructure development and management. With its modest storage capacity and low hazard potential, the dam exemplifies the importance of local government initiatives in ensuring water security and flood control. As climate change continues to impact water resources globally, structures like the Pattee Creek Watershed P-2 dam play a crucial role in adapting to and mitigating the effects of changing environmental conditions in the region.

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.
