Summary
With a height of 15 feet and a storage capacity of 56 acre-feet, the dam serves as an important water resource for the surrounding area. Situated on Lost Creek offstream, the dam covers a surface area of 7 acres and has a drainage area of 162 square miles.
Managed by the Rock Island District of the US Army Corps of Engineers, Dolan Dam has a low hazard potential and is currently rated as "Not Rated" in terms of condition assessment. While the dam does not have a spillway or outlet gates, it provides valuable water storage for fire protection and recreational purposes. Despite not being regulated by the state or having a regular inspection schedule, Dolan Dam continues to play a crucial role in water management for the community of Spickardsville.
For water resource and climate enthusiasts, Dolan Dam represents a unique example of a privately owned structure that contributes to local water supply and ecosystem health. With its earth construction and buttress core type, the dam showcases engineering ingenuity in balancing water storage needs with environmental considerations. As climate change impacts water availability, Dolan Dam serves as a reminder of the importance of sustainable water management practices to ensure resilience in the face of changing conditions.

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.
