Summary
Constructed in 2004, this dam stands at a height of 24 feet and has a storage capacity of 130 acre-feet. With a surface area of 6.5 acres and a drainage area of 0.02 square miles, Sg Palo plays a crucial role in water resource management in the region.
Despite its low hazard potential and fair condition assessment, Sg Palo is considered to have a high risk level, indicating the importance of regular inspections and maintenance. The dam does not have a spillway and is not associated with any locks, emphasizing the need for careful monitoring of water levels and discharge. With the last inspection conducted in April 2019, it is essential for stakeholders to stay vigilant in ensuring the safety and functionality of this vital water infrastructure.
As climate change continues to impact water resources, Sg Palo serves as a key piece of infrastructure supporting agricultural activities in the area. With its strategic location and design, this dam plays a crucial role in ensuring a reliable water supply for irrigation, highlighting the importance of sustainable water management practices in the face of evolving climate patterns.

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.
