Summary
With a height of 31 feet and a length of 178 feet, the dam has a storage capacity of 71 acre-feet and serves a drainage area of 0.55 square miles. Situated on TR- Whiskey Run along the Mississippi River, Terrill Dam is regulated by the Iowa DNR and undergoes regular inspections, with a low hazard potential and a moderate risk assessment.
Despite its modest size, Terrill Dam plays a crucial role in water resource management in the region, providing storage for firefighting efforts and supporting local wildlife. The dam's location in a rural area highlights its importance for maintaining water quality and supporting ecological diversity. While not currently rated for its condition, Terrill Dam's construction and management reflect a commitment to sustainability and responsible water use, showcasing the essential role of private infrastructure in climate resilience and natural resource protection.
As climate change continues to impact water resources and ecosystems, Terrill Dam stands as a testament to the importance of small-scale infrastructure in mitigating risks and adapting to changing conditions. With its earth construction and soil foundation, the dam exemplifies a practical solution for local water management needs. By adhering to regulatory standards, undergoing regular inspections, and maintaining a low hazard potential, Terrill Dam sets a positive example for private dam owners in safeguarding water resources and enhancing climate resilience in the face of environmental challenges.

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.
