Summary
Completed in 1982, the dam stands at a height of 30 feet and has a length of 530 feet. Its primary purpose is grade stabilization, although it also serves for fire protection, stock or small fish pond, and recreation. The dam holds a storage capacity of 103 acre-feet, with a normal storage level of 45 acre-feet, covering a surface area of 1 acre.
Situated on TR-SO Farius Creek within the Rock Island District, Leeser Dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. With a moderate risk level of 3, the dam does not have an Emergency Action Plan (EAP) in place or updated emergency contacts. While the dam has not been inspected recently and does not meet inspection guidelines, it presents a manageable risk with no reported incidents.
For water resource and climate enthusiasts, Leeser Dam offers an intriguing case study in private dam ownership and management. With its multiple purposes and modest storage capacity, the dam exemplifies the diverse roles that such structures can play within local communities. While its risk level is moderate, the lack of recent inspections and emergency preparedness highlight areas for improvement to ensure the continued safety and functionality of the dam.

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.
